Weekly Top Performances: LCM Power Points Leaderboard (May 7–13) | Edition 02 The second week of May brought another strong slate of long course performances — and a few results worth a closer look. 📸 See this week's Instagram highlights → Each week, Swim Standards ranks the top long course meter performances entered into the system by power points, with one swim per swimmer per age/gender group and a top-three cutoff per division. This week's window covers entries from May 7–13, 2026, drawn from 74,000+ source rows across nearly 15,000 unique swimmer entries. Here's who stood out. 10 & Under Girls Nine-year-olds swept the 10&U girls podium this week. Annie Ma (PAC/IL) leads with a 945-point 50 fly in 34.14 — a quick, powerful swim that earned AAAA. Nya Ferguson (UN/FG) follows at 897 points with a 1:20.64 in the 100 fly, and Olivia Posegay (NTRO/ST) rounds out the trio with an 840-point 50 back in 38.91. Ferguson and Posegay both posted AAA standards. Rank Name Age Team Event Time Points 1 Annie Ma 9 PAC 50 Fly 34.14 945 2 Nya Ferguson 9 UN 100 Fly 1:20.64 897 3 Olivia Posegay 9 NTRO 50 Back 38.91 840 Boys Nine-year-old Luke Gamino (TCA/FL) posted the week's most eye-catching age-group swim, clocking a 32.92 in the 50 fly for 1,020 points — AAAA and well clear of the field. Roman Kuleshov (SAS/FG) earns second with a 938-point 200 IM in 2:50.41, and Leo Madera (GRSC/FG) takes third with a 50 breast in 38.83 for 901 points. All three earned AAAA.

Emma Saragossi (MAC/NC) leads with a 950-point 200 fly in 2:32.43, followed closely by teammate Livie Vaden (MAC/NC) at 910 points with a 2:35.97 in the same event — both earning AAAA. Josie Sun (MTRO/NT) rounds out the group with an impressive 800/1000 free in 9:31.44 for 895 points, also AAAA.

Elite training environments showing up in the data. Boys The 11-12 boys leaderboard was headlined by an extraordinary distance swim. Eleven-year-old Philip Scharper (NBAC/MD) tops the entire weekly board across all age groups with 1,082 points on an 18:22.89 in the 1500/1650 free — a remarkable feat of endurance and composure at that age. Ethan Zhang (SRQ/FL) follows with a 987-point 200 breast in 2:50.33, and Graham Musser (ASA/PV) slots third with a 2:52.83 in the same event for 961 points.

Going 18:22 in the 1500/1650 at age 11 long course is a serious marker for a distance prospect. 13–14 Girls The 200 IM dominated the 13-14 girls podium. Kate Allen (CSC/IN) leads with a 2:19.54 for 952 points, and teammate Grace Gannon (FAST/IN) follows at 932 points with a 2:20.65 — both 13-year-olds, both AAAA. Zaryna Wardlay (MTRO/NT) rounds out the group with a 905-point 50 free in 26.81, also AAAA.

Alex Kirsling (NTRO/ST) follows at 944 points with a 1:02.63 in the 100 back, and Rui Rui An (CSC/IN) takes third with a 938-point 400/500 free in 4:06.15. All three posted AAAA.

Ellie Clarke (CSC/IN) follows at 978 points with a 1:01.39 in the 100 back, and Julie Mishler (UOFL/KY) takes third with a 1:02.25 in the same event for 943 points. All three earned AAAA.

Wilson York (LAK/KY) and Yi Zheng (CSC/IN) are tied at exactly 1,023 points — York on a 2:14.60 in the 200 breast, Zheng on a 4:17.06 in the 400 IM. York earns the top ranking by tiebreaker. Josiah Collins (UN-01/IN) takes third with a 990-point 200 breast in 2:16.80. All three posted AAAA.

Week at a Glance Highest score overall: Philip Scharper (11-12 Boys) — 1,082 pts Top performance of the week: Scharper's 18:22.89 in the 1500/1650 free at age 11 — distance swimming at its most impressive Exact tie: Wilson York and Yi Zheng both scored 1,023 in the 15-18 Boys group — different events, identical points Club watch: CSC/IN placed swimmers in three of the four older age groups; Indiana is having a strong week Event trends: Butterfly, breaststroke, and IM events dominated across the board; backstroke claimed the top two spots in 15-18 girls Standards: 21 of 24 swimmers earned AAAA; Nya Ferguson, Olivia Posegay, and Graham Musser posted AAA Rankings based on power points from performances entered into Swim Standards between May 7–13, 2026.

How the names on your heat sheet compare to the ones topping the SSA charts — and what a 15-year lag looks like in the water. Every May, the Social Security Administration releases its annual baby name rankings — and for swim fans, it's a natural excuse to check the heat sheet. Names cycle through culture, then through age groups, and eventually they land on a touchpad. So how does the pool stack up against the country right now? We pulled swimmer profile data from our database and matched it against the SSA's 2026 national rankings. Here's what we found. In the Pool: Most Popular Names in U.S. Club Swimming Boys Rank Name Registered Swimmers 1 Ethan 3,828 2 William 3,512 3 Jack 3,432 4 Andrew 3,114 5 Ryan 2,914 6 Luke 2,875 7 Matthew 2,793 8 Noah 2,640 9 Jacob 2,633 10 Henry 2,595 Girls Rank Name Registered Swimmers 1 Emma 5,240 2 Olivia 4,850 3 Sophia 3,739 4 Ava 3,482 5 Ella 3,290 6 Emily 3,069 7 Grace 2,985 8 Charlotte 2,910 9 Anna 2,831 10 Elizabeth 2,592 Nationally: SSA Top 10 Baby Names (2026) Released May 8, 2026. Liam and Olivia hold the #1 spots nationally for the seventh consecutive year. Boys: Liam, Noah, Oliver, Theodore, Henry, James, Elijah, Mateo, William, Lucas Girls: Olivia, Charlotte, Emma, Amelia, Sophia, Mia, Isabella, Evelyn, Sofia, Eliana Where the Lists Overlap Six names appear on both the SSA national rankings and our club swimming data: Olivia · Emma · Sophia · Charlotte · Noah · Henry That's a meaningful overlap — but it tells a slightly different story depending on which side of the lane line you're looking at. What's Going On Here The girls' lists are nearly in sync. Emma (#1 nationally, #1 in the pool), Olivia (#1 SSA, #2 in swim data), Sophia (#5 SSA, #3 in swim data), and Charlotte (#2 SSA, #8 in swim data) all rank highly on both lists. If you're coaching a girls' age group practice right now, you're almost certainly calling two or three of those names per lane — and that's not going to change anytime soon. The boys' lists reflect a generational lag. Ethan, Jack, Andrew, and Matthew don't crack the SSA top 10 for 2026 — but they were extremely popular names in the late 2000s to early 2010s, which is exactly when today's competitive-age swimmers were born. The national #1, Liam, doesn't appear in our swim data at all yet. Give it a decade. Noah and Henry are the crossover names on the boys' side. Noah ranks #8 in the pool and #2 nationally; Henry sits at #10 in swim data and #5 on the SSA list. These names bridged the generational gap — popular enough in the early 2010s to fill age group lanes now, and still trending nationally today. And then there's Ethan. The #1 boys' name in our entire database. Not in the SSA top 10. Not close. A quiet, definitive statement about what swim parents were naming their sons around 2008–2012. 😅 A Note for Anyone Searching If you're looking up a swimmer with a common name — and after reading this, you know exactly which names those are — add a team or LSC to narrow your results. It'll save you a lot of scrolling. And if you've spotted duplicate swimmer profiles in our database, feel free to message us. We're happy to merge them. What's the most common name on your team?

Ultimate Muscle Soreness & Tiredness Guide For Swim Meets Don't let "heavy legs" ruin your finals. The race doesn't end at the wall—it ends when your recovery is done. Here is how to stay fresh from the first heat to the last relay. THE PRE-GAME: Get Your Muscles "Awake" Stop static stretching before you race! You want your muscles snappy, not over-relaxed. Dynamic Swings: 15 big arm circles + leg swings to lubricate the joints. Muscle Slapping: Lightly pat your quads and arms to jumpstart blood flow. Band Work: Use a resistance band for 10 "pull-aparts" to activate your back. Box Breathing: 4s inhale, 4s hold, 4s exhale. Calm the nerves, find the focus. THE POST-GAME: Flush the Burn The faster you start recovery, the faster you can go in your next event. The 300 Rule: NEVER skip your 300m easy warm-down. It flushes out the lactic acid. Dry & Wrap: Get out of that wet suit and into a parka ASAP. Warm muscles stay pliable; cold muscles get stiff. Refuel Window: Eat a banana or granola bar within 15 mins to reload your energy tanks. Good luck at the meet! 🏁

Ranked by Time | Data via Swim Standards | Long Course Meters The long course season is officially underway. This is our April month-end snapshot of the top LCM swims logged on Swim Standards — covering meets held throughout April 2026, with no limit per swimmer, event, or meet. Because results from some meets may still be processed, a small number of April swims could appear after this snapshot date. Starting next week, we'll be posting Weekly Top Performances every Wednesday as the long course season builds into the summer. 🏆 Highlights & Standout Swims A few swimmers dominated the April leaderboards, and the 2026 FG Fort Lauderdale Open (April 29) served as the de facto early-season showcase — accounting for the majority of top performances across both the girls' and boys' sides. Girls' Side Rylee Erisman (Windermere Lakers / FL, age 17) was arguably the performance of the month on the girls' side. The 17-year-old swept the 100 free (54.10, 1,002 pts), 200 free (1:57.63, 1,001 pts), and 200 back (2:08.20, 1,025 pts) — each ranking first in their respective 18 & Under events. Her 200 back was the highest power point total posted by any 18-and-under female swimmer in April. Sadie Buckley (NCAP / PV, age 16) was right behind her. Buckley swept the 200 IM (2:12.35, 1,005 pts), 400 IM (4:39.79, 977 pts), 200 back (2:09.95, 994 pts), and 100 back (1:01.16, 987 pts), plus added a 200 fly victory (2:13.46, 919 pts). She was the most versatile multi-event performer of the month. Audrey Derivaux (Jersey Wahoos / MA, age 16) made a strong opening statement in the sprint-to-distance freestyle events, topping the 100 fly (58.68, 981 pts) and ranking among the leaders in the 200 and 400 free. Mikayla Tan (San Ramon Valley Aquatics / PC, age 16) was the standout on the West Coast, posting the top 100 breast (1:08.74, 961 pts) and 200 breast (2:28.11, 970 pts) at the Pacific Swimming LCM Senior Open. She also placed in the 100 fly and 200 IM. Sydney Hardy (Sarasota Sharks / FL, age 15) was the April distance queen, topping the 1500 free (16:42.76, 939 pts) and posting the month's top 15-16 200 IM (2:16.55, 932 pts). She added a 400 free win as well. Boys' Side Jayden Tsai (Windermere Lakers / FL, age 14) put up one of the most eye-catching performances of the month regardless of age group. The 14-year-old swept the 200 IM (2:07.56, 1,015 pts), 400 IM (4:30.97, 1,001 pts), and 200 fly (2:04.39, 999 pts) — elite power point totals at any age. Joey Eaddy (Revolution Aquatic Club / NE, age 15) was impressive across a wide range of events: 200 back (2:03.06, 1,000 pts), 800 free (8:09.55, 982 pts), 400 free (3:58.31, 938 pts), and 1500 free (15:39.04, 945 pts). He was the most productive distance/backstroke swimmer of the month. Liam Carrington (Bolles School Sharks / FL, age 18) led the boys in the 100 back (55.48, 957 pts), 50 back (26.19), and 50 free (22.84 — wait, that's Smelzer) — a classic Bolles sprinter-backstroker profile showing up early in the long course season. Juan Vallmitjana (South Florida Aquatic Club / FG, age 17) swept the distance freestyle events, winning the 800 free (7:57.70, 975 pts), 1500 free (15:22.96, 940 pts), and 400 free (3:53.80, 932 pts) — all at Fort Lauderdale. Charlie Russell (Bolles School Sharks / FL, age 16) was the month's top 15-16 breaststroker, posting the highest power point total in the 100 breast (1:03.68, 970 pts) among 18-and-under swimmers. Bolles School Sharks were the most represented club on the boys' side, placing multiple swimmers at or near the top of back, breast, fly, and free — a reminder that the Jacksonville program remains one of the premier early-season LCM programs in the country. 📊 Girls 18 & Under — Top 6 by Time 50 Freestyle Swimmer Age Club Time Pts Penelope Lopez-Casula 14 Eagle Aquatics 25.83 952 Kennedi

Fort Lauderdale dominated the calendar. The 2026 FG Fort Lauderdale Open (April 29) produced the majority of the top swims for both girls and boys — a clear signal that this meet has become a premier early-season LCM destination. Rylee Erisman and Sadie Buckley were the two most dominant girls of the month, each leading multiple events at high power point levels. Jayden Tsai (age 14) and Joey Eaddy (age 15) were the most impressive boys performers, both posting 1,000+ power point swims across multiple events. Bolles School Sharks were the most represented club on the boys' side, appearing across back, breast, fly, and free at the top of nearly every event leaderboard. Results may still be added. Some April swims could appear in the database after this snapshot. This list reflects data available at time of generation. Data sourced from Swim Standards. Power Points reflect age-group adjusted scoring. Snapshot generated May 5, 2026.

We all know getting a cramp while swimming is awful, but you can usually fix it with some easy access items. A big spoonful of yellow mustard is a classic hack because the vinegar and salt kickstart your nerves to make the muscle relax fast. If you don't have mustard, drinking a splash of pickle juice or eating a banana works wonders too. Just make sure to stretch it out and keep drinking water with a pinch of salt to keep those muscles happy. 💪💪💪 I personally, as a swimmer use Chick-Fil-A mustard packets, and just keep them in my dry bag at a meet or practice to quickly banish cramps. 🏊‍♂️

Revision (May 1, 2026): This post has been updated to correct a filtering issue in the original dataset. The initial version only included swimmers whose best times were recorded in the 17–18 age group. This excluded some age-eligible swimmers whose best times were set at age 16. The analysis below now reflects age eligibility as of August 1, 2026. Data current as of April 23, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 17 or 18 as of 8/1/2026) The Boys 17-18 LCM record book contains some of the most recognizable names in American swimming history. Michael Phelps holds the 200 free, 200 IM, and 400 IM from 2003. Caeleb Dressel's 50 free from 2015. Thomas Heilman's 100 fly, set just last year. Campbell McKean's sprint breaststroke marks from 2025. And Luca Urlando's 200 fly from 2019. The result is a mixed landscape: some records that were set at a generational level and remain comfortably protected, and a few — particularly in the IM, breaststroke, and distance freestyle — where the current field is projecting into genuinely competitive range. Baylor Stanton remains the multi-event story, appearing across backstroke, breaststroke, and IM with projections that clip or approach several marks. Collin Holgerson appears across five events and leads on real performance in several. The revised dataset significantly reshapes the distance events and 400 IM. Luka Mijatovic now emerges as a central name, with real long course performances already at or near record level across multiple freestyle distances and the 400 IM. As with other age groups: classical backstroke conversion can be aggressive. Last-season LCM references are the more reliable measure in those events, and that context is flagged where relevant. Sprint Freestyle 50 Freestyle — NAG: 21.53 | Caeleb Dressel (2015) Dressel's 50 free has been on the books for over a decade. Albert Smelzer (18) leads at 19.26 SCY (22.18 projected, +3.02%), with a last-season LCM reference of 22.68 — 1.15 seconds and 5.34% above the record in actual competition. Mike Rice (18) and Jordan Ragland (18) both project to 22.20, with last-season LCM references of 23.00 and 23.04 — further back in real terms. Smelzer's 22.68 leads the field in real competition — 1.15 seconds above Dressel's record. In the 50 free at this age, that gap is meaningful. The record is protected. 100 Freestyle — NAG: 48.38 | Maximus Williamson (2023) This event has the tightest projections in the sprint picture. Jordan Ragland (18) leads at 42.24 SCY (48.49 projected) — just 0.11 seconds and 0.23% above Williamson's 2023 record on paper. His last-season LCM reference of 51.02, however, puts him 2.64 seconds above the record in actual competition — a substantial gap that reflects the conversion challenge in the sprint 100 free. Liam Carrington (18) follows at 48.58 projected (+0.41%), with a 51.38 last-season LCM reference. Mike Rice (18) rounds out the group at 48.75 projected (+0.76%), with the most advanced real 100 free LCM time at 49.84 — already sub-50 in long course last summer. Rice's 49.84 last-season LCM time is the most developed real baseline in this event — already under 50 seconds in actual competition, and 1.46 seconds above the record. The projections for Ragland and Carrington look tight on paper, but their real references are the honest measure. Rice is the most credible real-world threat. Distance Freestyle 200 Freestyle — NAG: 1:45.99 | Michael Phelps (2003) Phelps's 200 free has stood for 23 years. Luka Mijatovic (17) now leads the field with a last-season LCM best of 1:45.92 — already slightly under the record in real competition. His projection of 1:46.13 (+0.13%) closely aligns with that performance. Liam Carrington projects to 1:46.30, but his last-season LCM reference of 1:55.52 (+8.99%) reveals a large projection-to-performance gap. Hayden Vicknair (17) projects to 1:47.81 (+1.72%), with a 1:54.92 LCM reference. Mijatovic’s 1:45.92 last-season LCM time is the defining data point in this event — already at record level in real competition. This shifts the 200 free from a projection-based discussion to a confirmed high-performance event. 400 Freestyle — NAG: 3:46.01 | Ryan Erisman / Ethan Ekk (2025) A 2025 co-record with maximum recency protection — but one that has already been challenged in real terms. Luka Mijatovic leads with a last-season LCM time of 3:45.71 — slightly under the listed record in actual competition. His projection of 3:39.34 further reinforces that level. Trent Allen (17) follows at 3:49.41 projected, with a last-season LCM reference of 3:52.40 — 6.39 seconds and 2.83% above the record. Maxwell Stanislaus (18) projects to 3:49.28 without a confirmed long course baseline. Mijatovic’s 3:45.71 last-season LCM time effectively resets the context of this event — the record has already been matched or exceeded in recent competition. This becomes one of the clearest real-performance events in the dataset. 800 Freestyle — NAG: 7:45.19 | Luke Whitlock (2024) Luka Mijatovic (17) now leads, projecting to 7:37.70 (-0.97%) with a last-season LCM reference of 7:53.80 — 8.61 seconds and 1.85% above the record in real competition. Colin Jacobs (17) follows at 7:51.44 projected (+1.34%), with a last-season LCM reference of 8:01.99 — still a strong real baseline. Inyoung Kim (18) projects close on paper but remains significantly back in real terms. Mijatovic’s combination of projection and real performance makes him the most credible distance threat in the dataset. His 7:53.80 last-season LCM time places him firmly within striking distance of Whitlock’s record. 1500 Freestyle — NAG: 14:45.29 | Larsen Jensen (2004) A 2004 record that has lasted over two decades. Luka Mijatovic (17) leads at 14:47.41 projected (+0.24%), with a last-season LCM reference of 15:16.31 — the closest real performance among current swimmers. Gabriel Manteufel (18) follows at 14:57.81 projected, with a 15:15.08 LCM reference. Ellis Crisci (17) and Colin Jacobs round out the group. Mijatovic’s projection sits just 0.24% off a 22-year-old record, with the strongest real LCM baseline in the field. This is now a legitimate event to watch. Backstroke Classical backstroke conversion note: projections in the 50, 100, and 200 back clip the records on paper. Last-season LCM references — which are 3–10% above the marks — are the more reliable guide to where this field stands. 50 Backstroke — NAG: 24.63 | Michael Andrew (2017) All three candidates project under the record — Collin Holgerson at 23.75 (-3.57%), Benjamin Jaggers (18) at 24.23 (-1.62%), Erkhes Enkhtur (18) at 24.37 (-1.06%). Last-season LCM references of 25.64, 26.11, and 26.09 put the real picture in focus: all three were 1.01–1.48 seconds above the record in actual competition. Holgerson's 25.64 is the most developed real sprint back reference — about 1 second above the record. The gap is real in a 50 back at this level. Classical conversion significantly flatters the projections here. 100 Backstroke — NAG: 53.27 | Daniel Diehl (2022) Collin Holgerson projects to 51.08 (-4.11%) — well under the record on classical conversion — with a last-season LCM reference of 55.19 (+3.6%). Davis Jackson (17) projects to 52.15 (-2.1%), with a 55.43 last-season LCM reference (+4.05%). Baylor Stanton rounds out the group at 52.39 projected (-1.65%), with a 56.13 last-season LCM reference. All three candidates were 1.92–2.86 seconds above Diehl's record in last-season LCM competition — that's the real picture. Holgerson leads in real terms at 55.19. The backstroke conversion issue is most pronounced in this event. 200 Backstroke — NAG: 1:55.15 | Aaron Peirsol (2002) The 200 back is where backstroke projections and real references are most aligned in this dataset. Davis Jackson (17) projects to 1:52.58 (-2.23%), with a last-season LCM reference of 2:01.22 (+5.27%). Collin Holgerson projects to 1:53.11 (-2.04%), with a last-season LCM reference of 1:59.45 (+3.73%) — the most advanced real 200 back LCM time in the group. Baylor Stanton follows at 1:53.17 projected, with a 1:59.60 last-season LCM reference (+3.86%) — nearly identical to Holgerson's. Holgerson's 1:59.45 and Stanton's 1:59.60 are both within 4% of Peirsol's 2002 record in real competition — the most credible real backstroke references in the boys field. The record still has meaningful protection, but both swimmers are operating at a level that merits attention over the next cycle. Breaststroke 50 Breaststroke — NAG: 26.90 | Campbell McKean (2025) A 2025 record with maximum recency protection. The top three candidates all project in the 27.84–27.88 range — roughly 3.5% above the record. Jake Lloyd (18) is the standout on real performance: his last-season LCM reference of 27.79 (+3.31%) is actually slightly faster than his own projection of 27.88, and it's the closest any candidate gets to the record in real competition. Austin Carpenter (18) and Andrew Eubanks (18) have no last-season LCM references available. Lloyd's 27.79 last-season LCM time is the most relevant real data point — already 0.89 seconds above McKean's very fresh record. The record is protected by its recency, but Lloyd is the most credible real sprint breast reference in this field. 100 Breaststroke — NAG: 58.96 | Campbell McKean (2025) Another 2025 McKean record. Collin Holgerson leads at 51.75 SCY (59.44 projected, +0.81%), with a last-season LCM reference of 1:02.02 — 3.06 seconds and 5.19% above the record in actual competition. Ian Call (17) follows at 52.51 SCY (1:00.29 projected), with a last-season LCM reference of 1:00.49 — the most advanced real 100 breast LCM time in the group, and the tightest projection-to-reference alignment of any candidate in this event. Andrew Eubanks rounds out the group at 52.59 SCY (1:00.37 projected), with a 1:00.79 last-season LCM reference. Call's 1:00.49 last-season LCM time is the most credible real benchmark — 1.53 seconds and 2.59% above McKean's record in actual competition, with near-perfect alignment between his projection and real reference. Despite the record's 2025 recency, Call is the name to track most closely in this event. 200 Breaststroke — NAG: 2:08.91 | Matthew Fallon (2021) This is one of the most compelling events in the boys 17-18 dataset. Andrew Eubanks projects to 2:09.54 (+0.49%), with a last-season LCM reference of 2:12.85 — 3.94 seconds and 3.06% above Fallon's record in actual competition. Baylor Stanton follows at 2:09.83 projected (+0.71%), with a last-season LCM reference of 2:21.53 (+9.79%) — a very large real gap suggesting his long course 200 breast development is still in early stages. Collin Holgerson rounds out the group at 2:10.13 projected (+0.95%), with a last-season LCM reference of 2:21.62 (+9.86%) — essentially identical to Stanton's real baseline. Eubanks's 2:12.85 last-season LCM time is the most credible real reference — he's been within 3.94 seconds and 3.06% of Fallon's record in actual competition. His projection of +0.49% is also the tightest among the three candidates on both measures. If he closes that real gap this summer, Fallon's 2021 record moves into genuine conversation. Butterfly 50 Butterfly — NAG: 23.22 | Michael Andrew (2017) Brady Campbell (17) stands out in this event. His last-season LCM reference of 23.90 (+2.93%) closely matches his projection of 23.81 (+2.54%) — tight alignment that confirms real long course sprint fly efficiency. Mattaus Rammel (18) leads on projection at 23.73 (+2.2%), but his last-season LCM reference of 25.18 (+8.44%) is considerably further back in real terms. Brandon Ha (18) rounds out the group at 24.05 projected, with a 24.37 last-season LCM reference (+4.95%) — more aligned than Rammel. Campbell's projection-to-reference alignment is the most credible sign of genuine long course butterfly form in this event. His 23.90 last-season LCM time leads the field in real performance — 0.68 seconds above Andrew's record. That's a real gap in the 50 fly, but his conversion efficiency makes him the swimmer to watch. 100 Butterfly — NAG: 50.70 | Thomas Heilman (2025) Set just last year at a level the current field hasn't approached. Rowan Cox (18) leads at 45.47 SCY (51.87 projected, +2.31%), with a last-season LCM reference of 52.93 — 2.23 seconds and 4.4% above Heilman's record in actual competition. Mike Rice follows at 52.34 projected, with a last-season LCM reference of 55.03 (+8.54%) — a large real gap suggesting limited long course 100 fly experience. Brandon Ha rounds out the group at 52.60 projected, with a 53.90 last-season LCM reference. Cox's 52.93 leads the field in real competition — 2.23 seconds above a record set last year. Heilman's mark has recency protection on top of a real margin. Ha's last-season LCM reference of 53.90 is the second-most developed real baseline. 200 Butterfly — NAG: 1:53.84 | Luca Urlando (2019) Hayden Vicknair (17) leads at 1:43.06 SCY (1:57.20 projected, +2.95%), with a last-season LCM reference of 1:59.83 — 5.99 seconds and 5.26% above the record in actual competition. Mattaus Rammel follows at 1:57.69 projected, with a last-season LCM reference of 2:06.83 (+11.41%) — a very large real gap. Brandon Ha rounds out the group at 1:57.72 projected, with a 2:01.63 last-season LCM reference (+4.08%) — the most credible real 200 fly baseline, already under 2:02. Ha's 2:01.63 last-season LCM time is the most advanced real reference — 7.79 seconds above Urlando's record in actual competition. Vicknair leads on projection. The record has clear protection, but Ha's real performance level makes him a name to follow as the season develops. Individual Medley 200 IM — NAG: 1:55.94 | Michael Phelps (2003) Phelps's 200 IM is one of two records he holds in this dataset, both from 2003. Baylor Stanton projects to 1:56.00 — just 0.06 seconds and 0.05% above the record on paper. His last-season LCM reference of 2:01.46 (+4.76%) is the real measure: 5.52 seconds above the record in actual competition. The projection-to-reference gap is large — the same pattern seen in several events across this dataset where exceptional SCY form has yet to fully translate to long course. Collin Holgerson follows at 1:57.79 projected (+1.6%), with a 2:04.51 last-season LCM reference. Griffin Oehler (17) rounds out the group at 1:58.11 projected, with a 2:03.83 last-season LCM reference — the most aligned of the three between projection and real performance. Stanton's 0.05% projection gap is the closest any swimmer gets to a standing record in the entire boys dataset. His 2:01.46 last-season LCM reference — 5.52 seconds above the record — is the honest baseline. Phelps's 2003 IM marks are comfortably protected, but Stanton's SCY level is worth watching as a long-term indicator. 400 IM — NAG: 4:09.09 | Michael Phelps (2003) This event shifts meaningfully in the revised dataset. Luka Mijatovic (17) leads at 4:10.76 projected (+0.40%), with a last-season LCM reference of 4:16.18 — the closest real mark in the field. Yi Zheng (17) follows closely, projecting to 4:11.37 (+0.55%) with a 4:18.55 last-season LCM reference. Baylor Stanton remains competitive at 4:11.13 projected, with a 4:19.48 LCM reference. Mijatovic’s 4:16.18 and Zheng’s 4:18.55 establish this as a real-performance event rather than a projection-driven one. While Phelps’s record remains protected, this is now one of the deepest and most credible events in the dataset. Overall Picture Luka Mijatovic (17) emerges as one of the defining names in the dataset, leading across the 200, 400, 800, and 1500 freestyle events as well as the 400 IM. His profile is distinguished by real long course performances already at or near record level. Baylor Stanton (18) remains the central multi-event projection story, while Collin Holgerson continues to provide the most consistent real long course profile across multiple strokes. Yi Zheng strengthens the 400 IM field, adding depth to what is now one of the most competitive events in the dataset. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Backstroke projections in particular can run aggressive with classical conversion — last-season LCM references are the more reliable indicator in those events. Last-season LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff.

Revision (May 1, 2026): This post has been updated to correct a filtering issue in the original dataset. The initial version only included swimmers whose best times were recorded in the 17–18 age group. This excluded some age-eligible swimmers whose best times were set at age 16. The analysis below now reflects age eligibility as of August 1, 2026. Data current as of April 23, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 17 or 18 as of 8/1/2026) The Girls 17-18 LCM record book reads like a who's who of American swimming's recent past. Katie Ledecky holds the entire distance free lineup. Regan Smith owns both the 100 and 200 backstroke. Lilly King's 200 breast from 2015 is on the board. Alex Walsh, Torri Huske, Claire Curzan, Lydia Jacoby — the list of record holders reflects the depth of talent this age group has produced over the last decade. Against those marks, this winter's 17-18 field is led by Charlotte Crush, who appears across eight events and projects near or into several records. The revised dataset also brings Rylee Erisman into sharper focus across sprint and mid-distance freestyle, where her real long course references are among the strongest in the field. Kayla Han remains a key distance and IM name, and Molly Sweeney leads one of the most compelling breaststroke events in the dataset. A standing note on backstroke: classical SCY-to-LCM conversion produces aggressive results in backstroke at this age. Projections that appear to clip records should be read alongside last-season LCM references, which are the more reliable measure of where swimmers actually stand in long course competition. Sprint Freestyle 50 Freestyle — NAG: 24.43 | Claire Curzan (2022) Rylee Erisman (17) now leads the field at 21.67 SCY (24.85 projected, +1.72%), with a last-season LCM reference of 24.74 — just 0.31 seconds and 1.27% above Curzan's record in actual competition. Charlotte Crush (18) follows at 21.98 SCY (25.20 projected, +3.15%), with a last-season LCM reference of 26.08. Riley Anderson (18) rounds out the group at 22.07 SCY (25.30 projected), with a 25.65 last-season LCM reference. Erisman's 24.74 last-season LCM time changes the tone of this event. The record is still protected, but the real gap is only 0.31 seconds — much closer than the rest of the field. She is the clear name to watch in the 50 free. 100 Freestyle — NAG: 53.25 | Simone Manuel (2014) Manuel's 100 free has been on the books since 2014, and Rylee Erisman (17) now makes this event much more interesting. She leads at 46.73 SCY (53.47 projected, +0.41%), with a last-season LCM reference of 53.78 — just 0.53 seconds and 1.0% above the record in actual competition. Charlotte Crush follows at 47.72 SCY (54.57 projected, +2.48%), with a last-season LCM reference of 55.54. Zoe Smith rounds out the group at 47.80 SCY (54.66 projected), with a 56.49 last-season LCM reference. Erisman's 53.78 last-season LCM time is the defining real-world data point in this event — only 0.53 seconds off Manuel's record. This shifts the 100 free from safely protected to genuinely worth watching. Distance Freestyle 200 Freestyle — NAG: 1:54.43 | Katie Ledecky (2016) Ledecky's 200 free has held since 2016. Rylee Erisman (17) now leads the field at 1:40.93 SCY (1:55.23 projected, +0.70%), with a last-season LCM reference of 1:57.29 — 2.86 seconds and 2.50% above the record in actual competition. Charlotte Crush follows at 1:44.67 SCY (1:59.38 projected, +4.33%), with a last-season LCM reference of 2:01.19. Elizabeth Eichbrecht (18) rounds out the group at 1:59.81 projected, with a 2:01.31 last-season LCM reference. Erisman's 1:57.29 last-season LCM time is the strongest real 200 free baseline in this group. Ledecky's record remains protected, but Erisman changes this from an internal sub-2:00 storyline to a much more competitive watch. 400 Freestyle — NAG: 3:58.37 | Katie Ledecky (2014) Rylee Erisman (17) leads on projection at 4:05.08 (+2.81%), though no last-season LCM reference is available. Sydney Schoeck (18) follows at 4:08.01 projected, with a last-season LCM reference of 4:15.99. Kayla Han (18) rounds out the top three projections at 4:08.36, with the most advanced real 400 free LCM time in this group: 4:10.38 — 12.01 seconds above the record in actual competition. Erisman leads the projection list, but Han's 4:10.38 remains the most relevant real long course benchmark. The record has 12+ seconds of real-world protection — Ledecky's distance marks remain well guarded. 800 Freestyle — NAG: 8:06.68 | Katie Ledecky (2016) Kayla Han leads at 8:29.67 projected (+4.72%), with a last-season LCM reference of 8:35.91 — over 29 seconds above the record in real competition. Sydney Schoeck follows at 8:30.77 projected, with a last-season LCM reference of 8:41.91. Elizabeth Eichbrecht rounds out the group at 8:36.78 projected, with an 8:48.54 last-season LCM reference. Han's 8:35.91 last-season LCM time leads the field. Ledecky's 2016 records at distance are among the most protected marks in age group history — the real-world gap confirms that. 1500 Freestyle — NAG: 15:25.48 | Katie Ledecky (2015) All three candidates project and swim well above Ledecky's 1500 record. Sydney Schoeck leads at 16:10.80 projected, with a last-season LCM reference of 16:28.74 — over a minute above the record in real competition. Kayla Han follows at 16:17.09 projected, with a 16:28.92 last-season LCM reference. Paige Downey (18) rounds out the group at 16:23.22 projected, with a 16:22.67 last-season LCM reference — her real performance is actually slightly ahead of her own projection. Ledecky's distance records at 17-18 are in a category of their own. The field is competitive within itself — Schoeck and Han trading mid-16s — but the records are not under realistic pressure. Backstroke Classical backstroke conversion note: all three 50BK and 100BK projections clip the records on paper. Last-season LCM references — which are 3–8% above the records — are the more reliable guide to where this field actually stands. 50 Backstroke — NAG: 27.43 | Leah Shackley (2025) A 2025 record with maximum recency protection. All three candidates project under it on classical conversion — Alyssa Sagle (18) at 26.93 (-1.82%), Charlotte Crush at 27.08 (-1.28%), Brynn Lavigueur (18) at 27.42 (-0.04%). Last-season LCM references of 28.35, 28.47, and 28.37 put the real picture in focus: all three were roughly 0.92–1.04 seconds above the record in actual competition last summer. The projections here reflect SCY speed, not current LCM form. Last-season LCM references in the 28.35–28.47 range are the honest baseline — all within about 1 second of a mark set just last year, which is genuinely close but not a present threat given its recency. 100 Backstroke — NAG: 57.57 | Regan Smith (2019) Charlotte Crush projects to 56.82 (-1.3%) — under the record on paper — with a last-season LCM reference of 59.30 (+3.01%). That 1.73-second gap between her real performance and Smith's record is the honest measure. Alyssa Sagle projects to 57.32 (-0.43%), with a last-season LCM reference of 1:00.64. Rylee Erisman (17) is third at 58.69 projected, with a strong last-season LCM reference of 59.39 — nearly identical to Crush in real competition. Crush's 59.30 and Erisman's 59.39 are the two most developed real backstroke references in this group, both roughly 1.7–1.8 seconds above Smith's record. The record remains protected, but Erisman's inclusion gives this event more real long course depth. 200 Backstroke — NAG: 2:03.35 | Regan Smith (2019) The 200 back is the most compelling backstroke event in the girls dataset — and one where the projection and real reference are closer than the shorter backstroke events. Charlotte Crush projects to 2:03.66 (+0.25%), just 0.31 seconds above Smith's record on paper. Her last-season LCM reference of 2:07.05 (+3.0%) puts her 3.70 seconds above the record in actual competition — a real gap, but meaningfully smaller than in the 50 and 100 back. Alyssa Sagle follows at 2:05.57 projected (+1.8%), with a 2:11.54 last-season LCM reference. Sydney Schoeck rounds out the group at 2:06.15 projected, with a 2:11.81 last-season LCM reference. Crush's 2:07.05 last-season LCM time is the most advanced real reference in the backstroke field — 3.7 seconds and 3.0% above Smith's record. The projection gap is just 0.25%, but the real reference is the starting point. A meaningful drop in her long course 200 back this summer would put this record in genuine conversation. Breaststroke 50 Breaststroke — NAG: 30.20 | Lydia Jacoby (2022) The 50 breast field sits realistically 6–7% above Jacoby's record. Sofia Szymanowski (17) leads at 27.84 SCY (31.90 projected, +5.63%), with a last-season LCM reference of 32.36 (+7.15%). Kate Canales (17) follows at 28.11 SCY (32.20 projected, +6.62%), with a last-season LCM reference of 32.23 — the most advanced real 50 breast LCM time in this group. Molly Workman (18) rounds out the group at 32.44 projected, with a 33.56 last-season LCM reference. The record has solid protection in all three cases. Canales has the best real LCM reference at 32.23, while Szymanowski leads on projection. The 6%+ real gap to Jacoby's mark is meaningful in the 50 breast. 100 Breaststroke — NAG: 1:04.95 | Lydia Jacoby (2021) The 100 breast field projects 4–5% above the record, with last-season LCM references in the 1:08–1:09 range. Molly Sweeney (18) leads at 59.24 SCY (1:07.76 projected, +4.33%), with a last-season LCM reference of 1:08.98 — 4.03 seconds above the record in actual competition. Eliza Wallace (18) follows at 1:07.91 projected, with a 1:09.62 last-season LCM reference. Kayda Geyer (18) rounds out the group at 1:08.17 projected, with a 1:09.28 last-season LCM reference. Jacoby's record has clear protection at this level. Sweeney leads the field — her 1:08.98 last-season LCM time is the best real 100 breast reference in the group, though still 4 seconds back of the mark. 200 Breaststroke — NAG: 2:24.47 | Lilly King (2015) This is one of the most compelling events in the girls 17-18 dataset. Molly Sweeney projects to 2:24.66 — just 0.19 seconds and 0.13% above King's 2015 record on paper. Her last-season LCM reference of 2:28.92 (+3.08%) puts her 4.45 seconds above the record in real competition, which is the honest baseline. Kaidy Stout (17) follows at 2:26.88 projected (+1.67%), with a last-season LCM reference of 2:28.63 — the fastest real 200 breast LCM time in this group. Kayda Geyer (18) rounds out the group at 2:27.09 projected, with a 2:28.79 last-season LCM reference. Sweeney's projection is one of the closest in the dataset to a standing record on paper — 0.13%. Her 2:28.92 last-season LCM time is the real baseline, while Stout and Geyer actually lead narrowly in real long course performance. If Sweeney closes her LCM gap by 4 seconds this summer, King's 2015 record moves into genuine conversation. Butterfly 50 Butterfly — NAG: 25.43 | Claire Curzan (2022) The 50 fly field sits roughly 5–10% above Curzan's record in real terms — meaningful protection in a sprint event. Abby Chan (17) leads on projection at 26.70 (+4.99%), though her last-season LCM reference of 28.08 is significantly further back. Lucy Velte (17) follows at 26.90 projected (+5.78%), with a last-season LCM reference of 26.84 — the best real 50 fly LCM time in this group and closely aligned with her projection. Mia Buff (18) rounds out the group at 27.11 projected, with no last-season LCM reference available. Velte's 26.84 last-season LCM time is the standout real data point — the best actual long course performance in the group and closely aligned with her projection. Chan leads on converted SCY speed, but Velte is the more credible real-performance reference. 100 Butterfly — NAG: 55.66 | Torri Huske (2021) Charlotte Crush projects to 56.90 (+2.23%), with a last-season LCM reference of 58.09 — 2.43 seconds above Huske's record in actual competition. Nikki Nixon (17) follows at 58.61 projected, with a 1:01.25 last-season LCM reference. Clare Watson (18) rounds out the group at 58.84 projected, with a 1:00.14 last-season LCM reference. Crush's 58.09 last-season LCM time leads the field — 2.43 seconds and 4.37% above Huske's record in real competition. Protected for now, but her continued butterfly development is worth noting given her overall profile. 200 Butterfly — NAG: 2:06.10 | Alex Shackell (2024) A 2024 record with recency protection. Alyce Lehman (18) leads at 1:53.84 SCY (2:09.16 projected, +2.43%), with a last-season LCM reference of 2:10.82 — 4.72 seconds above the record in actual competition. Nikki Nixon (17) follows at 2:09.38 projected, with a 2:14.83 last-season LCM reference. Clare Watson rounds out the group at 2:09.66 projected, with a 2:11.83 last-season LCM reference — the second-best real baseline in this group. Shackell's 2024 record has real protection across both projection and reference measures. Lehman leads the field in actual competition at 2:10.82, still 4.72 seconds back. This event is one to track on a longer horizon. Individual Medley 200 IM — NAG: 2:09.01 | Alex Walsh (2019) Sadie Buckley (17) now leads the field at 1:54.84 SCY (2:10.67 projected, +1.29%), with a last-season LCM reference of 2:13.64 — 4.63 seconds and 3.59% above Walsh's record in actual competition. Charlotte Crush follows closely on projection at 2:10.71 (+1.32%), but her last-season LCM reference of 2:17.15 shows a larger real gap. Lucy Velte (17) rounds out the group at 2:11.62 projected, with a 2:18.14 last-season LCM reference. Buckley's 2:13.64 last-season LCM time is the most relevant real reference — 4.63 seconds above Walsh's record and clearly ahead of the rest of this field. Crush remains close on projection, but Buckley leads the event in both converted and real long course terms. 400 IM — NAG: 4:31.41 | Katie Grimes (2023) Sadie Buckley (17) leads on projection at 4:36.21 (+1.77%), with a last-season LCM reference of 4:45.21. Kayla Han follows at 4:36.44 (+1.85%), with the strongest real LCM reference in the field: 4:40.58 — 9.17 seconds and 3.38% above Grimes's 2023 record in actual competition. Sydney Schoeck rounds out the group at 4:37.48 projected, with a 4:43.20 last-season LCM reference. Buckley leads on projection, but Han's 4:40.58 remains the most relevant real benchmark. Not an imminent threat, but Han still provides the most credible real-world pressure on this record in the current field. Overall Picture Charlotte Crush (18) remains one of the defining names of the Girls 17-18 dataset — appearing in eight events, with projections that clip or approach records in the backstroke, butterfly, and IM picture. The consistent theme across her profile, however, is a gap between her exceptional SCY performances and her current long course results. Her real LCM gaps in the 100 back (3.01%), 200 IM (6.31%), and 200 free (5.91%) are all meaningfully larger than her projection gaps suggest. The 200 back (3.0% real gap, 0.25% projection) is the event where the two measures are most aligned — and the one where her long course development matters most to watch. Rylee Erisman (17) is the major addition in the revised dataset. Her real long course references in the 50 free (24.74), 100 free (53.78), 200 free (1:57.29), and 100 back (59.39) immediately change the profile of the girls field. The 100 free is especially notable: 53.78 is only 0.53 seconds off Simone Manuel's 2014 record, making it one of the strongest real-performance watches in the dataset. Kayla Han (18) remains one of the most proven long course performers in the dataset. Her last-season LCM references in the 400 free (4:10.38), 800 free (8:35.91), and 400 IM (4:40.58) are among the strongest real-world baselines across those events. Her continued push toward the sub-4:10 400 free and sub-4:40 400 IM are the more meaningful milestones to track — ahead of any specific record. Molly Sweeney (18) carries the most compelling breaststroke projection story: her 200 breast projection of 2:24.66 is just 0.13% above King's 2015 record. Her last-season LCM reference of 2:28.92 (3.08% above the record) is the realistic baseline, while Kaidy Stout and Kayda Geyer are slightly ahead in real long course performance. Sadie Buckley also becomes an important IM name, leading the 200 IM in both projection and real LCM reference. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Backstroke projections in particular can run aggressive with classical conversion — last-season LCM references are the more reliable indicator in those events. Last-season LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff (swimmer remains 17 or 18 as of 8/1/2026).

Data current as of April 23, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 15 or 16 as of 8/1/2026) The Boys 15-16 LCM record book is a patchwork of eras. Luka Mijatovic rewrote the distance free picture in 2025, setting marks in the 200, 400, and 800 free that carry maximum recency protection. Thomas Heilman holds the butterfly events from 2023. Michael Andrew's sprint marks from 2015 and 2016 have been on the books for a decade. And tucked into the distance free section is Bob Hackett's 1500 free from 1976 — the oldest record in the dataset. Against that backdrop, this winter's 15-16 field is among the more competitive in recent memory. Syunta Lee is the most versatile performer, leading the distance and IM picture. Kai Joyner is the other multi-event anchor. And across sprint, backstroke, and breaststroke, a deeper field of event specialists rounds out the picture. A note on backstroke events: classical SCY-to-LCM conversion can produce aggressive results in backstroke for this age group. Where projections clip records but last-season LCM references show a larger gap, both are noted — and the real references carry more weight. Sprint Freestyle 50 Freestyle — NAG: 22.33 | Michael Andrew (2016) Peter Kovacs (16) leads at 20.03 SCY (23.03 projected, +3.13%), with a last-season LCM reference of 23.28 — 0.95 seconds and 4.25% above the record in actual competition. Aiden Zhou (16) follows at 20.09 SCY (23.10 projected), with a 23.35 last-season LCM reference. Hutchison Paxton (16) rounds out the group at 20.17 SCY (23.19 projected), with a 23.96 last-season LCM reference — further back in real terms. In the 50 free at 15-16, a 1-second gap is meaningful. Kovacs and Zhou both showed ~23.3 last summer — the record has real protection, but both are tracking in the right direction for next cycle. 100 Freestyle — NAG: 48.81 | Kaii Winkler (2023) Peter Kovacs leads at 43.79 SCY (50.21 projected, +2.87%), with a last-season LCM reference of 51.72 — 2.91 seconds above the record in actual competition. Charles Cancelmo (16) follows at 44.08 SCY (50.53 projected), with a more advanced real baseline of 51.06 (+4.61%) — the most developed real 100 free LCM time in this group. Mason Crowley (16) rounds out the group at 44.22 SCY (50.68 projected), though his 53.45 last-season LCM reference (+9.51%) reflects limited long course sprint free experience to date. Cancelmo's 51.06 last-season LCM time leads the field on real performance — he's been within ~2 seconds of Winkler's 2023 mark in actual competition. The record is protected, but the sprint free field has real depth. Distance Freestyle 200 Freestyle — NAG: 1:45.92 | Luka Mijatovic (2025) Set just months ago, Mijatovic's 200 free carries the strongest recency protection in the dataset. Kai Joyner (16) leads at 1:34.91 SCY (1:48.55 projected, +2.48%), with a last-season LCM reference of 1:50.81 — 4.89 seconds and 4.62% above the record in actual competition. Noah Stotler (16) projects to 1:49.13, with a 1:53.96 last-season LCM reference reflecting a larger real gap. Charles Cancelmo rounds out the group at 1:49.36 projected, with a 1:52.45 last-season LCM reference. Joyner's 1:50.81 last-season LCM time leads the field in real terms — within 5 seconds of a mark set just last year. The record is protected by its recency and real margin, but Joyner's development is the storyline to track. 400 Freestyle — NAG: 3:45.30 | Luka Mijatovic (2025) Another 2025 Mijatovic record. Kai Joyner projects to 3:50.04 (+2.1%), with a last-season LCM reference of 3:56.67 — 11.37 seconds and 5.05% above the record in actual competition. Syunta Lee (16) follows at 3:52.06 projected, with a last-season LCM reference of 3:56.83 — nearly identical to Joyner's in real terms. Treyvn Krauss (16) rounds out the group at 3:53.83 projected, with a 4:01.53 last-season LCM reference. Joyner and Lee both showed 3:56 last summer — the most credible real baselines in this event, and roughly 11 seconds above a very fresh record. The 3:50 barrier is within reach on projection; closing that gap in real swims is the summer's challenge. 800 Freestyle — NAG: 7:48.28 | Luka Mijatovic (2025) A third 2025 Mijatovic record, and the projections here are notable. Kai Joyner projects to 7:57.54 (+1.98%), a projection gap of under 2%. His last-season LCM reference of 8:16.38, however, puts him 28 seconds above the record in actual competition — a large real gap that reflects how recently this record was set at an elite level. Owen Miklos (16) follows at 8:00.04 projected, with a last-season LCM reference of 8:22.15. Leopold Nurit (16) rounds out the group at 8:03.24 projected, with an 8:26.97 last-season LCM reference. Mijatovic set this mark in 2025 at a level the current field hasn't reached in real competition. Last-season LCM references in the 8:16–8:27 range confirm the distance. The projection picture is encouraging for Joyner's development, but the record is firmly protected. 1500 Freestyle — NAG: 15:03.91 | Bob Hackett (1976) The oldest record in this dataset by five decades — and this is one of the most intriguing events in the boys picture. Kai Joyner projects to 15:14.55 (+1.18%), a tight gap on paper. His last-season LCM reference of 15:40.92 (+4.09%) is the more honest measure, still 37 seconds above Hackett's mark in actual competition. Syunta Lee follows at 15:24.67 projected, with a 15:52.64 last-season LCM reference. Owen Miklos rounds out the group at 15:28.61 projected, with a 16:02.40 last-season LCM reference. Hackett's 1976 record has survived fifty years for a reason. Joyner's last-season LCM reference of 15:40.92 is the most advanced real baseline in this event — 37 seconds above the mark in actual competition. The projection is encouraging, but the 1500 is an event where real long course performance matters more than any conversion. Backstroke As noted, classical conversion can be aggressive in backstroke. The 50 and 100 back projections below clip or approach records on paper — last-season LCM references are the more reliable indicator of where things actually stand. 50 Backstroke — NAG: 25.13 | Michael Andrew (2015) All three candidates project within 0.84% of the record — with Joey Salvetti (16) projecting to 25.19 (+0.24%) and Graham Henderson (16) to 25.22 (+0.36%). Last-season LCM references tell a different story: Salvetti went 27.70 (+10.23%) and Henderson 26.84 (+6.8%) — both reflecting the typical SCY-to-LCM backstroke conversion gap at this age. Mason Crowley rounds out the group at 25.34 projected, with a 28.40 last-season LCM reference (+13.01%). Henderson's 26.84 last-season LCM time is the most developed real reference in this event — still 1.71 seconds above the record. The projections here are a product of aggressive classical backstroke conversion; the real baselines are the honest measure. 100 Backstroke — NAG: 53.27 | Daniel Diehl (2022) Three candidates project within a tight 54.19–54.25 window — all approximately +1.73–1.84% above the record on paper. Last-season LCM references of 58.07, 56.99, and 58.52 reflect the familiar backstroke conversion gap. Austin Chu (16) has the most developed real reference at 56.99 (+6.98%), while Grant Bellin (16) and Graham Henderson (16) showed 58.07 and 58.52 respectively last summer. Chu's 56.99 last-season LCM time leads the field on real performance — still 3.72 seconds above Diehl's 2022 record. Classical conversion produces projections within 2% of the record, but last-season references in the 57–58 range are the realistic baseline. The record is protected. 200 Backstroke — NAG: 1:57.03 | Aaron Peirsol (2000) The most interesting backstroke event in the boys dataset — and one where the last-season LCM references are more aligned with projections than the shorter backstroke events. Grant Bellin projects to 1:56.42 (-0.52%, fractionally under the record), with a last-season LCM reference of 2:03.55 (+5.57%) — a real gap of 6.5 seconds. Denzo Senekal (16) follows at 1:57.90 projected (+0.74%), with a more developed last-season LCM reference of 2:01.00 (+3.39%) — the most credible real baseline in this event. Derek Hernandez-Ojeda (16) rounds out the group at 1:58.07 projected, with a 2:05.84 last-season LCM reference. Senekal's 2:01.00 last-season LCM reference is the most meaningful real data point — he's been within 3.97 seconds and 3.39% of Peirsol's 2000 record in actual competition. The backstroke conversion note applies to Bellin's projection, but the real picture across all three is encouraging. This event is one to track. Breaststroke 50 Breaststroke — NAG: 27.45 | Ian Call (2025) A 2025 record with strong recency protection. Reef McMeeking (15) leads at 25.17 SCY (28.94 projected, +5.43%), with a last-season LCM reference of 29.01 — essentially matching his projection, a strong sign of consistent long course breaststroke form. Parker Van Olst (16) follows at 29.13 projected, with a 29.62 last-season LCM reference. Kelly Sommer (16) rounds out the group at 29.21 projected with no last-season LCM reference available. Call's 2025 mark has real protection at 5+% above the field. McMeeking's projection-to-reference alignment is the most encouraging sign in this event — but a 1.49-second gap in the 50 breast is not trivial. 100 Breaststroke — NAG: 1:00.17 | Josh Matheny (2019) Wilson York (16) leads clearly at 53.56 SCY (1:01.45 projected, +2.13%), with a last-season LCM reference of 1:01.78 — 1.61 seconds and 2.68% above Matheny's record in actual competition. His projection and last-season reference are tightly aligned, confirming real long course breaststroke form. Adam Barlow (16) follows at 53.93 SCY (1:01.86 projected), with no last-season LCM reference available. Matthew Cuadros (16) rounds out the group at 54.21 SCY (1:02.17 projected), with a 1:04.31 last-season LCM reference. York's 1:01.78 last-season LCM time makes him the most credible real-world candidate in this event — he's been within 1.61 seconds and 2.68% of Matheny's record in actual competition. A focused 100 breast long course campaign this summer is worth watching. 200 Breaststroke — NAG: 2:09.40 | Josh Matheny (2019) Wilson York leads at 1:55.14 SCY (2:11.81 projected, +1.86%), with a last-season LCM reference of 2:13.21 — 3.81 seconds and 2.94% above Matheny's record in actual competition. His projection and reference are again closely aligned, reinforcing the same long course breaststroke efficiency he shows in the 100. Jack Maddan (16) follows at 2:12.17 projected, with a 2:16.99 last-season LCM reference. Matthew Cuadros rounds out the group at 2:14.56 projected, with a 2:19.38 last-season LCM reference. York's 2:13.21 last-season LCM reference is the most advanced real breaststroke time in this dataset — within 3 seconds and under 3% of a 2019 record. Paired with his 100 breast profile, he's the most complete real-performance breaststroke story in the boys field. Butterfly 50 Butterfly — NAG: 23.66 | Michael Andrew (2015) Jackson Shawhan (16) leads at 21.46 SCY (24.52 projected, +3.63%) with no last-season LCM reference available — an unknown baseline in this event. Ian Miller (16) follows at 21.56 SCY (24.63 projected), but his last-season LCM reference of 26.11 (+10.36%) suggests he's still early in his long course 50 fly development. Dryden Finley (16) rounds out the group at 21.64 SCY (24.72 projected), with a more developed last-season LCM reference of 25.43 (+7.48%). The record has meaningful real-world protection — last-season LCM references of 25–26 put the field 1.77–2.45 seconds above the mark in actual competition. Finley's 25.43 is the most advanced real baseline. 100 Butterfly — NAG: 51.19 | Thomas Heilman (2023) Charlie Cancelmo leads at 46.65 SCY (53.18 projected, +3.89%), with a last-season LCM reference of 53.20 — essentially matching his projection, a clear sign he converts well in the 100 fly. Ryker Levi (16) follows at 46.94 SCY (53.50 projected), with a 55.89 last-season LCM reference (+9.18%) that reflects a much larger real gap. Hutch Paxton (16) rounds out the group at 47.21 SCY (53.80 projected), with a 53.84 last-season LCM reference — also closely aligned with his projection. Cancelmo and Paxton both show tight projection-to-reference alignment in the 100 fly — both in the 53.2–53.8 range in last-season LCM competition. Heilman's 2023 record still has a real cushion, but those are genuinely fast real performances for this age group. 200 Butterfly — NAG: 1:53.82 | Thomas Heilman (2023) Charles Cancelmo leads at 1:42.00 SCY (1:56.02 projected, +1.93%), with a last-season LCM reference of 1:58.27 (+3.91%) — about 4.45 seconds above the record in actual competition. Noah Stotler (16) follows at 1:59.24 projected, with a last-season LCM reference of 2:05.27 (+10.06%) — a large real gap suggesting limited long course 200 fly experience. Luke Dunn (16) rounds out the group at 1:59.73 projected, with a 2:04.62 last-season LCM reference. Cancelmo's 1:58.27 last-season LCM time is the most developed real baseline — still 4.45 seconds above Heilman's 2023 record. His projection-to-reference alignment is again solid. The record has protection, but he's the most credible long course butterfly candidate in this field. Individual Medley 200 IM — NAG: 1:58.65 | Maximus Williamson (2023) Syunta Lee projects to 2:00.34 (+1.42%), with a last-season LCM reference of 2:02.94 (+3.62%) — about 4.29 seconds above the record in actual competition. Wilson York (16) follows at 2:01.07 projected, with a 2:03.75 last-season LCM reference (+4.3%). Charles Cancelmo rounds out the group at 2:01.48 projected, with a 2:08.30 last-season LCM reference — notably further back in real terms, suggesting his IM long course development trails his individual stroke form. Lee and York both showed 2:02–2:03 last summer — the most advanced real 200 IM baselines in this group, both within 4–5 seconds of Williamson's 2023 record. Lee leads on projection; their continued development through the summer is the story in this event. 400 IM — NAG: 4:14.73 | Carson Foster (2018) This is the most compelling event in the boys dataset. Syunta Lee projects to 4:15.48 — just 0.75 seconds and 0.29% above Foster's 2018 record on paper. His last-season LCM reference of 4:20.69 (+2.34%) puts him 5.96 seconds above the record in actual competition — a real gap, but one that aligns well with his overall development arc across distance and IM events. Kai Joyner follows at 4:18.86 projected (+1.62%), with a last-season LCM reference of 4:32.26 (+7.24%) — a much larger real gap suggesting limited 400 IM long course experience. Wilson York (16) rounds out the group at 4:19.17 projected, with a last-season LCM reference of 4:24.72 (+3.92%) — the second most developed real 400 IM baseline in the group. Lee's 4:20.69 last-season LCM time and 0.29% projection gap make this the most credible record watch in the entire boys dataset. He's been within 6 seconds of Foster's 2018 record in real competition — and his SCY 400 IM is operating at a level that puts the record in realistic range if he can close the conversion gap. This is the event to watch most closely when the long course season begins. Overall Picture Two swimmers carry the Boys 15-16 narrative this cycle, each from a different angle. Syunta Lee (16) is the most compelling story in the dataset. His 400 IM last-season LCM reference (4:20.69) is the closest any candidate gets to a standing record in real competition — 5.96 seconds and 2.34% above Foster's 2018 mark. His projection of 4:15.48 (+0.29%) is the tightest in the boys dataset. He also leads the 1500 free and 200 free fields in projection, and appeared competitively in the 200 IM and 400 free. His 400 IM is the boys event most worth watching when competition begins. Wilson York (16) is the breaststroke anchor. His last-season LCM references of 1:01.78 in the 100 breast and 2:13.21 in the 200 breast are the most advanced real breaststroke performances in the dataset — within 2–3% of Matheny's 2019 records in both events. He also appeared in the 200 IM with a credible real baseline. His long course breaststroke form is the most consistently developed of any specialist in this field. Kai Joyner leads on projection across the distance free events, with the most advanced last-season LCM reference in the 200 free (1:50.81). Charles Cancelmo leads the fly picture, with tight projection-to-reference alignment in both the 100 fly (53.20 last-season LCM) and 200 fly (1:58.27) — the latter representing the most credible real performance against a fly record in this dataset. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Backstroke projections in particular can run aggressive with classical conversion — last-season LCM references are the more reliable indicator in those events. Last-season LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff (swimmer remains 15 or 16 as of 8/1/2026).

Data current as of April 23, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 15 or 16 as of 8/1/2026) The Girls 15-16 LCM record book is anchored by two names more than any other: Katie Ledecky, who owns the entire distance free lineup from her 2013 season, and Claire Curzan, who set three sprint and stroke marks in 2019 and 2021. Against that backdrop, this winter's 15-16 field produced one of the more compelling SCY performances in recent memory — and a handful of events where the gap between current ability and standing records is genuinely narrow. Audrey Derivaux is the defining name of this dataset, appearing across nine events with projections and last-season LCM references that place her in realistic contention on multiple fronts. Gabi Brito and Reina Liu anchor the sprint picture. And Mikayla Tan owns the breaststroke field outright. A note on backstroke events: the classical SCY-to-LCM conversion used throughout this dataset can produce aggressive projections in backstroke, particularly for this age group. Where projections appear to clip records by more than the last-season LCM references suggest, the real reference times are the more reliable indicator. That context is noted in each relevant section. Sprint Freestyle 50 Freestyle — NAG: 24.17 | Claire Curzan (2021) The 50 free field is fast but the record has clear real-world protection. Reina Liu (16) and Gabi Brito (16) are essentially tied at 21.93 and 21.95 SCY, projecting to 25.14 and 25.16 LCM — both roughly 4% above Curzan's mark. Last-season LCM references of 25.46 and 25.42 confirm that gap is real: both swimmers were over a second above the record in actual competition last summer. Avery Daigle (16) rounds out the group at 22.21 SCY (25.45 projected), with a 26.12 last-season LCM reference. In the 50 free at this level, 1+ seconds is a meaningful gap. Liu and Brito are the class of the field in real terms — their head-to-head development is the internal story this summer. 100 Freestyle — NAG: 52.79 | Rylee Erisman (2025) Set just last year, Erisman's 100 free mark carries strong recency protection. Gabi Brito leads at 47.77 SCY (54.62 projected), with a last-season LCM reference of 55.49 — about 2.7 seconds above the record in actual competition. Reina Liu is right behind at 48.16 SCY (55.06 projected), with a 55.41 last-season LCM reference. Kennedi Southern (16) rounds out the group at 48.52 SCY (55.46 projected), with a 55.91 last-season LCM reference. The record is well protected in real terms — all three candidates were 2.6–3.1 seconds above it last summer. Brito leads the group on real long course performance. Distance Freestyle 200 Freestyle — NAG: 1:55.06 | Missy Franklin (2011) Franklin's 200 free has held since 2011. Reina Liu leads at 1:44.49 SCY (1:59.18 projected), with a last-season LCM reference of 2:01.02 — 5.96 seconds above the record in actual competition, which is a real gap in the 200 free at this level. Audrey Derivaux (16) follows at 1:44.95 SCY (1:59.69 projected), with a 2:01.78 last-season LCM reference. Abi Burke (15) rounds out the group at 1:45.56 SCY (2:00.37 projected), with a 2:02.20 last-season LCM reference. The field projects in the 1:59–2:00 range, still 4–5% above the record. Last-season LCM references in the 2:01–2:02 range confirm the distance. The record is protected, but Liu and Derivaux are both closing in on the sub-2:00 long course barrier, which is the more meaningful milestone this summer. 400 Freestyle — NAG: 3:59.82 | Katie Ledecky (2013) Ledecky's 400 free has stood for 13 years and the current field doesn't threaten it in real terms — last-season LCM references of 4:11.73 and 4:12.14 put the top candidates roughly 12 seconds above the record in actual competition. Audrey Derivaux projects to 4:08.20 (+3.49%), with a last-season LCM reference of 4:12.14. Brinkleigh Hansen (16) follows at 4:08.57 projected, with a 4:11.73 last-season LCM reference — the most advanced real 400 free LCM time in the group. Vivienne Zangaro (16) is third at 4:09.63 projected, with a 4:16.65 last-season LCM reference. Hansen's 4:11.73 last-season LCM time leads the field on real performance. The record has about 12 seconds of real-world protection — no imminent threat, but the 4:10 barrier is within reach for multiple swimmers this summer. 800 Freestyle — NAG: 8:13.86 | Katie Ledecky (2013) Audrey Derivaux leads at 8:30.20 projected (+3.31%), with no last-season LCM 800 reference available — this may be her first serious attempt at the event in a 50-meter pool. Vivienne Zangaro follows at 8:34.67 projected, with a last-season LCM reference of 8:53.72 (+8.07%) — a real baseline that shows 40 seconds of work remaining between her and the record in actual competition. Brinkleigh Hansen is third at 8:36.64 projected, with a last-season LCM reference of 8:46.19 — the most developed real 800 free LCM baseline in this group. Hansen's 8:46 is the most grounded real reference here. Ledecky's record has real protection at every level — but this event will tell us a lot about Derivaux's long course distance ceiling once she actually races it. 1500 Freestyle — NAG: 15:36.53 | Katie Ledecky (2013) Audrey Derivaux leads at 16:04.89 projected (+3.03%), with no last-season LCM 1500 reference — same unknown baseline as the 800. Zayda Miehl (16) and Ellie Clarke (16) follow with nearly identical projections around 16:28, with last-season LCM references of 16:37.99 and 16:38.64 respectively — over a minute above the record in real competition. Ledecky's distance records are among the most protected marks in age group swimming. The projection picture reflects that — Derivaux is the closest on paper, but without a real LCM baseline, that projection remains to be tested. Backstroke A note on backstroke projections: classical SCY-to-LCM conversion tends to produce aggressive results in backstroke for this age group. The 50 and 100 back projections below clip or approach the records on paper, but last-season LCM references tell a more measured story. Both are included — the projections show SCY ceiling, the references show where these swimmers have actually been. 50 Backstroke — NAG: 27.85 | Regan Smith (2018) All three candidates project under the record on paper — a classic case of aggressive backstroke conversion. Gabi Brito (27.08 projected) and Reina Liu (27.23 projected) are the more credible candidates based on last-season LCM references: Brito went 28.78 last summer (+3.34%) and Liu went 28.65 (+2.87%) — both real, competitive times that put them roughly 0.8–0.9 seconds above the record in actual competition. Katrin Otaegi (16) leads on projection at 27.07 but her last-season LCM reference of 29.87 (+7.25%) reflects a much earlier stage of long course backstroke development. Liu's 28.65 and Brito's 28.78 are the relevant real baselines — both within 1 second of Smith's record in actual competition. That's genuinely close in the 50 back. If either swimmer makes a significant LCM improvement this summer, this event is worth watching. 100 Backstroke — NAG: 58.82 | Claire Curzan (2021) The classical conversion again produces projections that clip the record — Liu at 57.81 (-1.72%), Brito at 58.32 (-0.85%), Hutchison at 58.78 (-0.07%). Last-season LCM references provide the real context. Shelby Hutchinson (16) has the most grounded reference at 1:01.49 (+4.54%), while Reina Liu's 1:01.07 (+3.83%) is the most advanced real 100 back LCM time in this group. Both are roughly 2–2.7 seconds above the record in actual competition. The projections here are better understood as a SCY performance ceiling than a reliable LCM forecast. Real last-season references put the field 2.5–4.5 seconds above the record — protected for now, but Liu's development arc in backstroke is one to track. 200 Backstroke — NAG: 2:05.10 | Missy Franklin (2011) This is the most compelling backstroke event in the girls dataset — and one of the most credible record watches overall. Audrey Derivaux projects to 2:06.31 (+0.97%), and her last-season LCM reference of 2:06.68 is just 1.26% above the record — the projection and the real reference are closely aligned, which makes this one credible on both measures. Reina Liu projects to 2:06.91, but her last-season LCM reference of 2:12.41 (+5.84%) reflects a much larger real gap. Ellie Clarke (16) is third at 2:08.02 projected, with a 2:11.68 last-season LCM reference. Derivaux's 2:06.68 last-season LCM time is the headline in this event — she's been within 1.58 seconds and 1.26% of Franklin's record in real competition. That's genuinely close at the 200 back level. This is one of the records most worth watching this summer. Breaststroke 50 Breaststroke — NAG: 30.78 | Emily Willham (2017) Mikayla Tan (16) leads and dominates this event. Her projection of 31.45 (+2.18%) is the tightest in the sprint breaststroke field, and her last-season LCM reference of 31.41 (+2.05%) is essentially the same — meaning the conversion math closely mirrors her actual performance, a strong sign of consistent long course form. Bianca Nwaizu (16) follows at 31.87 projected, with a 31.82 last-season LCM reference — again, projection and real reference nearly identical. Lane Francis (16) rounds out the group at 32.05 projected with no last-season LCM reference available. Tan and Nwaizu both show tight alignment between projection and last-season LCM reference — a sign both swimmers convert well in this event. The record is about 2% above their real performances, which in sprint breaststroke is meaningful but not out of reach on a multi-season horizon. 100 Breaststroke — NAG: 1:07.05 | Megan Jendrick (2000) A 26-year-old record — and this is one of the most compelling event watch lists in the dataset. Mikayla Tan and Bianca Nwaizu are essentially tied at the top — 59.04 and 59.05 SCY respectively, projecting to 1:07.53 and 1:07.55 — both just 0.48–0.50 seconds and under 0.75% above Jendrick's record on paper. Last-season LCM references of 1:09.36 (+3.45%) and 1:09.85 (+4.18%) put the real gap at roughly 2–3 seconds, which is a more honest measure of where things stand in actual competition. Grace Koenig-Song (16) is third at 1:08.91 projected, with a last-season LCM reference of 1:09.14 — the most advanced real 100 breast LCM time in the group. Tan and Nwaizu project within 0.75% of a 26-year-old record — that's a meaningful signal. Their last-season LCM references in the 1:09 range are the honest baseline, and Koenig-Song's 1:09.14 leads the field on real performance. If any of these three makes a 2-second LCM improvement this summer, Jendrick's record is in genuine jeopardy. 200 Breaststroke — NAG: 2:25.35 | Anita Nall (1992) A record from 1992 that may be the most vulnerable in this entire dataset. Mikayla Tan projects to 2:24.68 — fractionally under the record (-0.46%) on paper. More tellingly, her last-season LCM reference of 2:28.13 (+1.91%) puts her within 2.78 seconds of Nall's mark in actual competition. The projection and the reference both point in the same direction. Grace Koenig-Song (16) follows at 2:29.22 projected, with a 2:32.42 last-season LCM reference. Salem Bahr (16) rounds out the group at 2:29.48 projected, with a 2:32.45 last-season LCM reference. This is the record most likely to fall in 2026. Tan's projection clips it and her last-season LCM reference confirms she's been within 2.78 seconds in actual competition — a gap of under 2%. Her trajectory and consistency across all three breaststroke events make this one to watch closely when long course competition begins. Butterfly 50 Butterfly — NAG: 25.70 | Torri Huske (2019) Gabi Brito leads at 23.17 SCY (26.42 projected, +2.8%), with a last-season LCM reference of 26.47 — closely aligned with her projection, a sign she converts well in the 50 fly. Avery Daigle follows at 23.52 SCY (26.81 projected), though her last-season LCM reference of 27.98 (+8.87%) reflects a much larger real gap. Kennedi Southern (16) rounds out the group at 23.82 SCY (27.14 projected), with a 27.50 last-season LCM reference. Brito's 26.47 last-season LCM time leads the field in real performance — 0.77 seconds above the record, or 3.0%. In the 50 fly, that's a real gap. Her projection-to-reference alignment is the most encouraging sign in this event. 100 Butterfly — NAG: 56.20 | Claire Curzan (2021) Gabi Brito leads at 51.20 SCY (58.23 projected, +3.61%), with a last-season LCM reference of 59.49 — 3.29 seconds and 5.85% above the record in actual competition. Audrey Derivaux follows at 51.74 SCY (58.83 projected), with a last-season LCM reference of 58.63 — notably ahead of her own projection, confirming she converts efficiently in the 100 fly. Jianna Amores (15) rounds out the group at 51.78 SCY (58.88 projected), with a 1:00.12 last-season LCM reference. Derivaux's 58.63 last-season LCM time leads the field in real performance — 2.43 seconds above Curzan's record. That's about 4.3% and a real gap for the 100 fly, but her projection-to-reference alignment makes her the most credible long course candidate here. 200 Butterfly — NAG: 2:05.96 | Mary Meagher (1981) A 45-year-old record — and this is arguably the most striking real-performance story in the girls dataset. Audrey Derivaux projects to 2:07.90 (+1.54%), but her last-season LCM reference of 2:06.46 is just 0.50 seconds and 0.4% above Meagher's record. She was essentially at the record in actual long course competition last summer. Ellie Clarke (16) follows at 2:08.92 projected, with a last-season LCM reference of 2:12.43 (+5.14%). Reina Liu rounds out the group at 2:11.36 projected with no last-season LCM reference available. Derivaux's 2:06.46 last-season LCM time is the most important number in this entire girls dataset. She was already 0.5 seconds from Meagher's 45-year-old record in real competition last summer. A focused 200 fly campaign this season makes this record a genuine target. Individual Medley 200 IM — NAG: 2:08.91 | Leah Hayes (2022) Audrey Derivaux projects to 2:09.60 — just 0.69 seconds and 0.54% above Hayes's 2022 record. Her last-season LCM reference of 2:10.91 (+1.55%) puts her within 2 seconds of the record in actual competition. Both measures point in the same direction, and the alignment between projection and real reference is tight — a strong signal that her long course IM form matches her SCY level. Gabi Brito (16) follows at 2:11.69 projected (+2.16%), with a last-season LCM reference of 2:15.61 (+5.2%). Mikayla Tan rounds out the group at 2:12.10 projected, with a 2:15.20 last-season LCM reference. Derivaux's 2:10.91 last-season LCM time puts her within 2 seconds and 1.55% of Hayes's record in actual competition. Combined with a 0.54% projection gap, this is one of the more credible record threats in the dataset — and one that warrants close attention this summer. 400 IM — NAG: 4:32.67 | Katie Grimes (2022) Audrey Derivaux projects to 4:34.83 — just 2.16 seconds and 0.79% above Grimes's record. Her last-season LCM reference of 4:41.39 (+3.2%) is the more measured real baseline, putting her 8.72 seconds above the record in actual competition. Ellie Clarke (16) follows at 4:40.31 projected (+2.8%), with a last-season LCM reference of 4:45.45. Sydney Hardy (15) rounds out the group at 4:43.60 projected, with a 4:47.86 last-season LCM reference. Derivaux's 4:41 last-season LCM time is the most relevant real benchmark — she's been within 8.7 seconds of Grimes's record in actual competition. The projection gap of 0.79% is tight on paper; whether her IM long course form continues to close that gap is the question the season will answer. Overall Picture Audrey Derivaux (16) is the defining story of the Girls 15-16 LCM field this cycle. She appears across nine events, and unlike some multi-event profiles where SCY dominance outpaces real long course results, her last-season LCM references are consistently tight with her projections — a sign of genuine long course efficiency. The events that stand out most on real performance: 200 Butterfly: Her 2:06.46 last-season LCM time is 0.5 seconds and 0.4% from Meagher's 45-year-old record — the closest any swimmer in this dataset gets to a standing record in real competition. 200 IM: Her 2:10.91 last-season LCM reference puts her within 1.55% of Hayes's 2022 record. 200 Backstroke: Her 2:06.68 last-season LCM reference sits 1.26% above Franklin's 2011 record. 400 IM: Her projection (+0.79%) and real reference (+3.2%) both indicate continued pressure on Grimes's 2022 mark. Mikayla Tan (16) is the breaststroke story — her 200 breast last-season LCM reference of 2:28.13 is within 2% of Nall's 1992 record, with a projection that actually clips it. She also shows the tightest projection-to-reference alignment of any swimmer in this dataset across her breaststroke events, confirming she converts consistently in long course. Gabi Brito and Reina Liu (16) lead the sprint free and backstroke fields respectively in real long course performance, with development arcs that make both worth following through the summer. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Backstroke projections in particular can run aggressive with classical conversion — last-season LCM references are the more reliable indicator in those events. Last-season LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff (swimmer remains 15 or 16 as of 8/1/2026).

Data current as of April 23, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 13 or 14 as of 8/1/2026) The Boys 13-14 LCM record book was significantly rewritten between 2021 and 2024. Thomas Heilman set the sprint and butterfly marks in 2021. Luka Mijatovic then rewrote the distance free landscape in 2023 and 2024, taking the 200, 400, 800, and 1500 free as well as the 400 IM. The result is a record list where the most recently set marks carry strong recency protection. Against that backdrop, this winter's SCY field is deep. Elliot Leasure leads the way across backstroke, butterfly, and IM. Ayden Tan — just 13 years old — appears competitively across six events. And a handful of event-specific specialists round out the picture. The recurring theme on the boys side is a field with exceptional SCY speed that is still developing its long course conversion. Last-season LCM references are the honest measure of where things actually stand. Sprint Freestyle 50 Freestyle — NAG: 22.95 | Thomas Heilman (2021) Three sprinters are bunched tightly at the top of this event. Jesse Cyrus (14) leads at 21.16 SCY (24.29 projected), with a last-season LCM reference of 24.85 — about 1.9 seconds above the record on actual swims, which in the 50 free is a solid gap. Abram Webster (14) follows at 21.32 SCY (24.47 projected), with a last-season LCM reference of 25.72. Hank Cheng (14) rounds out the group at 21.34 SCY (24.49 projected), with a last-season LCM reference of 24.87 — the most advanced real sprint LCM time of the three, essentially matching Cyrus's projection. Cyrus and Cheng are the real-performance leaders in this event, both coming off last-season LCM times in the 24.85–24.87 range. The record has about 2 seconds of real-world protection — not insurmountable on a multi-season horizon, but not close in 2026. 100 Freestyle — NAG: 51.12 | Thomas Heilman (2021) Lubo Liu-Tchorbadjiyski (14) leads at 45.66 SCY (52.28 projected), with a last-season LCM reference of 53.30 — 2.18 seconds above the record on actual swims. He's the only candidate in this event with a real LCM time that projects credible development toward Heilman's mark. Ayden Tan (13) is second at 46.23 SCY (52.92 projected), with a last-season LCM reference of 54.91 — the former 11-12 NAG — showing he's been racing LCM competitively. Elliot Leasure (14) rounds out the group at 46.56 SCY (53.28 projected), with a 55.52 last-season LCM reference. Liu-Tchorbadjiyski's 53.30 last-season LCM time gives him the most credible real-world baseline in this event. The record still has over 2 seconds of real protection, but he's tracking in the right direction. Distance Freestyle 200 Freestyle — NAG: 1:49.63 | Luka Mijatovic (2024) A 2024 record with strong recency protection. Elliot Leasure leads at 1:39.24 SCY (1:53.36 projected), 3.73 seconds above the record on paper. His last-season LCM reference of 2:02.56 — from a May meet — shows this event is still early in its long course development for him. Jude Burkhart (14) projects to 1:55.41, with a last-season LCM reference of 1:57.01 — the most grounded real long course 200 free time in this group, and the baseline that best reflects where the field actually sits relative to the record. Miles Ayres (14) is third at 1:55.96 projected, with a 2:06.84 last-season LCM reference. Burkhart's 1:57.01 last-season LCM time leads the field in real performance. The record has roughly 7 seconds of real-world protection. Mijatovic's 2024 mark is well-guarded. 400 Freestyle — NAG: 3:51.18 | Luka Mijatovic (2024) The 400 free field projects tightly — Rui Rui An, Declan McDonald, and Hanz Palattao all convert within a narrow window of 4:04.05–4:04.55 — but the record is over 13 seconds above even the top projection. An's last-season LCM reference of 4:15.40 and Palattao's 4:16.07 are the most developed real baselines; McDonald's 4:26.37 reflects very early-season LCM racing. Mijatovic's 2024 mark is firmly protected. An and Palattao both went 4:15–4:16 last summer, which is where this field genuinely sits — a good 24 seconds from the record in real terms. 800 Freestyle — NAG: 7:59.64 | Luka Mijatovic (2023) Jude Burkhart leads the 800 free field at 8:21.50 projected, with a last-season LCM reference of 8:38.39 — the most developed real long course 800 baseline in this group, and about 38 seconds above the record on actual swims. Damien Orfanoudakis (14) projects to 8:23.10, with a last-season LCM reference of 9:03.84 — a larger gap that suggests his long course distance form is still building. Declan McDonald rounds out the group at 8:24.76 projected with no last-season LCM reference available. Burkhart's 8:38 last-season LCM time is the relevant real benchmark. The record has nearly 40 seconds of real-world protection — firmly safe this cycle. 1500 Freestyle — NAG: 15:26.73 | Luka Mijatovic (2024) Jude Burkhart leads at 15:54.70 projected, with a last-season LCM reference of 16:24.76 — nearly a minute above the record on actual swims. Jax Capen (14) and Damien Orfanoudakis both project around 16:10–16:11, with Capen's 16:42.63 last-season LCM reference more advanced than Orfanoudakis's 17:11.35. Mijatovic's 2024 1500 is the most protected distance record in this dataset — nearly 28 seconds clear of the top projection, and last-season LCM references a minute or more behind. Burkhart leads the field in real terms. Backstroke 50 Backstroke — NAG: 26.70 | Jack Alexy (2017) Elliot Leasure and Lubo Liu-Tchorbadjiyski both project under the record — 25.53 and 25.60 respectively — but their last-season LCM references of 27.72 and 27.30 show they were both above it in real competition last summer. Liu-Tchorbadjiyski's 27.30 is the more advanced real reference of the two. Ayden Tan (13) rounds out the group at 22.94 SCY (26.06 projected), with a 28.86 last-season LCM reference. Liu-Tchorbadjiyski leads on real long course performance in this event. The record has about 0.6 seconds of real-world protection based on last summer — closer than most events in this dataset, and a genuine watch if both swimmers continue to develop. 100 Backstroke — NAG: 56.36 | Thomas McMillan (2024) Elliot Leasure's projection of 54.16 from his 47.71 SCY is the most striking number on the boys side — 2.2 seconds under the record on paper. His last-season LCM reference of 57.78 tells the fuller story: he was 1.42 seconds above the record in actual competition last summer. That gap — from 57.78 to a projection of 54.16 — reflects the same SCY-to-LCM conversion question that runs through his entire profile. Ayden Tan (13) follows at 55.87 projected, with a 1:01.31 last-season LCM reference indicating very limited long course 100 back experience. Lubo Liu-Tchorbadjiyski is third at 55.98 projected, with a 59.88 last-season LCM reference. Leasure's 57.78 last-season LCM time is the real starting point — he was 1.42 seconds above the record last summer. Closing that gap is plausible; his projection suggests the ceiling is much higher. This is the most interesting backstroke watch in the dataset. 200 Backstroke — NAG: 2:00.28 | Keaton Jones (2019) Elliot Leasure projects to 1:57.76 — 2.52 seconds under the record on paper — with a last-season LCM reference of 2:07.32. That's a 7-second gap between his last-season LCM time and the record, which is a large step. Jaxson Daniel (14) follows at 2:03.15 projected, with a 2:13.35 last-season LCM reference. Ayden Tan (13) is third at 2:03.43 projected, with a 2:12.39 last-season LCM reference. Leasure's last-season LCM reference of 2:07.32 is the most developed real baseline in this event — but 7 seconds from the record in actual competition is a meaningful gap. His SCY speed suggests potential well beyond last summer. One to track carefully. Breaststroke 50 Breaststroke — NAG: 28.92 | Wilson York (2024) A 2024 record with recency protection. Hanz Palattao (14) leads at 26.35 SCY (30.25 projected) with no last-season LCM reference available — an unknown long course baseline. Eli Henley (14) follows at 26.51 SCY (30.43 projected), with a last-season LCM reference of 31.03. Landon Williams (14) rounds out the group at 26.59 SCY (30.51 projected), with a last-season LCM reference of 30.20 — actually faster than his own projection, suggesting his real long course form is already ahead of where conversion math places him. Williams's 30.20 last-season LCM time leads the field on real performance — within 1.28 seconds of York's 2024 mark in actual competition. The record is protected, but he's the most credible real threat in this event. 100 Breaststroke — NAG: 1:02.22 | Ian Call (2023) Hanz Palattao leads at 56.51 SCY (1:04.73 projected), with a last-season LCM reference of 1:08.25 — about 6 seconds above the record in real competition. Ryan Yao (14) follows at 56.97 SCY (1:05.24 projected), with a 1:09.88 last-season LCM reference. Landon Williams rounds out the group at 57.24 SCY (1:05.54 projected), with a 1:08.65 last-season LCM reference — the most advanced real 100 breast LCM time in this group. Call's 2023 record has 2.5+ seconds of protection over the top projection. Last-season LCM times in the 1:08–1:09 range confirm the field still has real development ahead before this mark is threatened. 200 Breaststroke — NAG: 2:15.11 | Wilson York (2024) Ryan Yao and Hanz Palattao share identical SCY bests of 2:03.19 and identical projections of 2:20.74 — a genuine statistical tie at the top of this event. Their last-season LCM references distinguish them: Palattao at 2:26.69 and Yao at 2:28.40, with Palattao holding a slight edge in real long course competition. Frederic Burks (14) is third at 2:21.30 projected, with a last-season LCM reference of 2:26.61 — nearly matching Palattao's real baseline. York's 2024 record has 5+ seconds of protection over the top projections. The more interesting story is Palattao and Burks both showing 2:26 last summer — their head-to-head development across the season is the internal competition to follow. Butterfly 50 Butterfly — NAG: 25.26 | Brady Campbell (2023) Lubo Liu-Tchorbadjiyski leads at 22.24 SCY (25.39 projected) — just 0.51% above the record on paper, the tightest projection gap in the boys dataset. His last-season LCM reference of 26.26 puts him 1 second above the record in real competition. Ayden Tan (13) follows at 22.43 SCY (25.60 projected), with a last-season LCM reference of 26.42. Asher Song (14) rounds out the group at 22.50 SCY (25.68 projected) with no last-season LCM reference available. Liu-Tchorbadjiyski's 26.26 last-season LCM time and 25.39 projection put this event on the genuine watch list. A 1-second gap in the 50 fly at 14 is real, but his projection and development arc make this the most plausible record threat on the boys side. 100 Butterfly — NAG: 53.27 | Thomas Heilman (2021) Elliot Leasure leads at 49.42 SCY (56.26 projected), with a last-season LCM reference of 59.40 — 6+ seconds above the record in actual competition. Ayden Tan (13) follows at 49.66 SCY (56.52 projected), with a 59.71 last-season LCM reference nearly identical to Leasure's. Jude Burkhart rounds out the group at 49.92 SCY (56.81 projected), with a last-season LCM reference of 58.48 — the most advanced real 100 fly LCM time in this group. Heilman's record has clear protection — last-season LCM references in the 58–59 range put the field 5–6 seconds back. Burkhart's 58.48 leads on real performance, but the record isn't under pressure this cycle. 200 Butterfly — NAG: 1:59.02 | Michael Phelps (2000) The most historically significant record in this dataset — set in 2000 and untouched for 26 years. Elliot Leasure projects to 2:01.97 — 2.95 seconds and 2.48% above the record. His last-season LCM reference of 2:08.18 shows he was 9+ seconds above the mark in real competition last summer. Steven Zhou-He (14) follows at 2:05.82 projected, with a last-season LCM reference of 2:11.09. Lubo Liu-Tchorbadjiyski rounds out the group at 2:06.91 projected, with a 2:18.84 last-season LCM reference — notably behind the other two in real long course form. Phelps's 2000 record is well protected at every level — projections and last-season LCM references both confirm the distance. Leasure's development in this event is worth tracking on a multi-season horizon, but 2026 is not the year. Individual Medley 200 IM — NAG: 2:03.73 | Shareef Elaydi (2024) A fresh 2024 record. Ayden Tan (13) leads at 1:50.02 SCY (2:05.32 projected) — 1.59 seconds and 1.29% above the record on paper. His last-season LCM reference of 2:12.80 — set as a 12-year-old, when it stood as the 11-12 NAG — provides context: he's been competitive in LCM IM since he was younger, and now enters the 13-14 age group with another full summer ahead. Elliot Leasure follows at 1:51.19 SCY (2:06.62 projected), with a last-season LCM reference of 2:12.73 — almost identical to Tan's real baseline. Hanz Palattao is third at 1:52.35 SCY (2:07.91 projected), with a 2:13.64 last-season LCM reference. Tan at 13 projecting to 2:05.32 is notable, but his last-season LCM reference of 2:12.80 — 9 seconds above the record — is the honest measure of where he currently stands in long course. The record is protected for now; Tan is the name to track as the season develops. 400 IM — NAG: 4:24.20 | Luka Mijatovic (2024) Elliot Leasure leads at 3:55.36 SCY (4:27.65 projected) — 3.45 seconds and 1.31% above the record on paper — with a last-season LCM reference of 4:46.11, over 21 seconds above the mark in actual competition. Jude Burkhart follows at 3:57.09 SCY (4:29.57 projected), with a notably more developed last-season LCM reference of 4:39.15 — 15 seconds above the record in real competition, and the most relevant real benchmark in this event. Declan McDonald rounds out the group at 3:57.54 SCY (4:30.07 projected), with a last-season LCM reference of 4:53.93 from an April time trial. Burkhart's 4:39.15 last-season LCM time is the most credible real data point in this event — he's been the closest to Mijatovic's record in actual competition. The record still has clear protection, but Burkhart is the swimmer applying the most real pressure. The Bigger Picture Two swimmers define the narrative of the Boys 13-14 LCM field this cycle, and both have a consistent theme: exceptional SCY speed paired with a long course conversion gap that the summer will begin to test. Elliot Leasure (14) leads or finishes near the top of every backstroke, butterfly, and IM event in this dataset. His projections in the 100 and 200 back are both mathematically under standing records, but his last-season LCM references in those events tell a more measured story — 1.42 seconds above the 100 back record, and 7+ seconds above the 200 back. The consistent theme is a swimmer with short course performance well ahead of his long course results so far. He has one more summer as a 14-year-old, and the 100 back is the event most worth watching given how close his last-season LCM time already was. Ayden Tan (13) appears in six events as a 13-year-old — 100 free, 50 and 200 back, 50 and 100 fly, and 200 IM — all while projecting competitively within the 13-14 age group. His last-season LCM references were set at 12, meaning every reference in this dataset was from a younger age group. He has two full summers remaining, and the 200 IM is the event where his trajectory is most interesting to follow. Beyond those two: Lubo Liu-Tchorbadjiyski is the 50 fly and sprint story — his 26.26 last-season LCM reference in the 50 fly makes that the most credible near-term record threat on the boys side. Jude Burkhart owns the distance and IM real-performance picture, with last-season LCM times that lead the field in the 200 free, 800 free, 100 fly, and 400 IM. And Landon Williams in the 50 breast, whose last-season LCM time outpaced his own projection, is a small but telling sign of efficient long course breaststroke form. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Last-season LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff (swimmer remains 13 or 14 as of 8/1/2026).

Data current as of April 23, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 13 or 14 as of 8/1/2026) The Girls 13-14 LCM record book spans nearly five decades of American swimming history. Sippy Woodhead's 1978 200 free sits alongside Grace Koenig-Song's 2024 50 breast. Amanda Beard's breaststroke marks from 1996 share the page with records set as recently as last summer. Against that backdrop, this winter's SCY field — led by the exceptional Finola Whelehan and the versatile Lauren Lonsdale — is one of the more compelling 13-14 classes in recent years. What follows is a candidate-by-candidate look at the current field, built from 2025–26 SCY performance and projected forward using classical conversion. Last-season LCM reference times are included throughout as a real-world check on what the projections actually mean in a 50-meter pool. Sprint Freestyle 50 Freestyle — NAG: 24.98 | Rylee Erisman (2024) The sprint free field is genuinely fast, but the gap to Erisman's 2024 record is real. All three candidates project in the 26.17–26.41 range — more than a second above the mark — and in the 50 free at 13-14, that distance matters. Natalia Lesniewska (14) leads at 22.86 SCY (26.17 projected), though her last-season LCM reference of 27.03 puts her over 2 seconds above the record on actual swims. Zaryna Wardlay (14) follows at 23.02 SCY (26.35 projected), with a last-season LCM time of 26.42 — her real performance is slightly ahead of her own projection, reflecting sound long course efficiency. Lauren Lonsdale (14) rounds out the group at 23.07 SCY (26.41 projected), with a 26.62 last-season LCM reference. The record has solid protection — a 1+ second gap in the 50 free at this age is not trivial. This is a developmental watch rather than a near-term threat. 100 Freestyle — NAG: 54.03 | Missy Franklin (2009) Franklin's 100 free has stood for 17 years, and the current field isn't projecting close enough to challenge it this summer. Natalia Lesniewska and Finola Whelehan (14) lead at nearly identical SCY bests — 49.34 and 49.37 — projecting to 56.37 and 56.40 LCM, both roughly 2.3–2.4 seconds above the record. Whelehan's last-season LCM reference of 56.75 is the most advanced real 100 free LCM time in this group, though it still sits 2.72 seconds short of the mark. Lauren Lonsdale rounds out the group at 49.68 SCY (56.74 projected), with a 57.37 last-season LCM reference. The record is comfortably protected. Whelehan leads on real long course performance, but the margin remains clear. Distance Freestyle 200 Freestyle — NAG: 1:58.53 | Sippy Woodhead / Claire Weinstein (1978 / 2022) One of the more unusual records in USA Swimming history — a tie between a 1978 swim and a 2022 performance that matched it exactly. The 200 free is the most interesting event in this dataset. Finola Whelehan projects to 1:59.69 from her 1:44.95 SCY — just 0.98% above the record on paper, which is genuinely notable. Her last-season LCM reference of 2:02.08 is the necessary context: she was still 3.55 seconds above the record in actual competition last summer, meaning how much of her winter improvement she carries into 50-meter pools is the key unknown. Lauren Lonsdale projects to 2:01.40, with a last-season LCM reference of 2:02.73. Kate Allen (14) rounds out the group at 2:02.76 projected, with a 2:06.13 last-season LCM reference. Whelehan's projection is the most compelling number in the girls dataset — breaking 2:00 LCM at 14 would be a significant achievement. Her 2:02.08 last-season LCM reference sets the realistic starting point. This is the event to watch most closely this summer. 400 Freestyle — NAG: 4:07.15 | Sippy Woodhead (1978) Woodhead's 400 free has survived 48 years of challengers. Lauren Lonsdale leads at 4:14.46 projected, with a last-season LCM reference of 4:15.61 at Futures Sacramento — her real performance closely matches her projection, and she's already been the closest any current 13-14 swimmer has come to this record in recent memory. That said, 7+ seconds at the 400 free level is still a substantial gap. Autumn McIntosh (14) projects to 4:17.93, though her last-season LCM reference of 4:32.98 reflects a field that is still developing long course form in this event. Kate Allen is third at 4:18.78 projected, with a 4:26.56 last-season LCM reference. The record is protected by a meaningful margin. Lonsdale's 4:15.61 last-season LCM time leads the field on real performance — her continued development is the storyline, not the record itself. 800 Freestyle — NAG: 8:28.54 | Becca Mann (2012) All three candidates project well above Mann's mark, with last-season LCM references in the 9:14–9:28 range confirming the field is still building toward this event in long course. Autumn McIntosh leads at 8:44.49 projected, with a last-season LCM reference of 9:15.68. Willa Kulp (14) and Madison Suchecki (14) follow at 8:56.87 and 8:57.90 projected, with last-season LCM references of 9:14.71 and 9:28.67 respectively. Mann's record is well protected. The more interesting story is how much of this field's winter improvement carries over to their first long course swims of the summer. 1500 Freestyle — NAG: 16:11.98 | Becca Mann (2012) Autumn McIntosh leads at 16:51.01 projected, with a last-season LCM reference of 17:44.72 — nearly a minute above the record on actual swims. Lauren Lonsdale follows at 17:01.10 projected, with a 17:34.35 last-season LCM reference. Harper Rauch (13) rounds out the group at 17:05.10 projected, with a 17:48.73 last-season LCM reference — the youngest candidate here, with the longest runway ahead. The record is not under pressure this cycle. McIntosh and Lonsdale both project under 17:05 — solid times in their own right, even if Mann's mark remains comfortably distant. Backstroke 50 Backstroke — NAG: 28.57 | Phoebe Bacon (2017) A data note: the top-ranked candidate, Jasmine Phillips (14), shows a SCY time of 17.42 with a projected LCM of 19.94 — consistent with a relay split or non-standard event entry rather than a standalone 50 back. Her last-season LCM reference of 37.60 confirms this. She is excluded from this analysis. Noel Defrancisco (14) leads at 24.88 SCY (28.22 projected), which clips the record on paper. Her last-season LCM reference of 35.52 makes the context clear: her long course backstroke development is still in early stages, and the projection is well ahead of where she's actually been in a 50-meter pool. Samantha Engel (14) follows at 25.41 SCY (28.81 projected), with a 40.54 last-season LCM reference. The last-season LCM references tell the definitive story here. Both candidates are well above the record in real competition — the projections reflect SCY speed, not current long course form. 100 Backstroke — NAG: 1:00.26 | Regan Smith (2016) Finola Whelehan posts the most eye-catching projection in the entire girls dataset: 1:00.09 from her 53.05 SCY — fractionally under Smith's 2016 mark on paper. Her last-season LCM reference of 1:04.47 provides the realistic context — a 4.21-second gap from her last known long course performance to the record. That's a large step in a single season for the 100 back. Lillie Dirito (13) follows at 1:00.77 projected, with a 1:10.13 last-season LCM reference indicating very limited long course backstroke experience. Lauren Lonsdale is third at 1:01.82 projected, with a more grounded 1:06.08 last-season LCM reference. Whelehan's SCY backstroke is exceptional and the projection reflects that honestly. But her 1:04.47 last-season LCM time is where the conversation actually starts — the record is a separate target that will require real improvement in long course form. 200 Backstroke — NAG: 2:09.16 | Missy Franklin (2009) The top three projections — 2:12.92, 2:12.96, 2:13.11 — are tightly bunched, all roughly 3–4 seconds above Franklin's record. Lauren Lonsdale leads on real performance: her last-season LCM reference of 2:15.86 puts her within 6.7 seconds of the record in actual competition, making her the most credible long course 200 back swimmer in this group. Finola Whelehan is essentially tied on projection at 2:12.96, but her last-season LCM reference of 2:25.17 reflects very early-season long course exposure in this event. Lillie Dirito (13) rounds out the group at 2:13.11 projected, with a 2:26.56 last-season LCM reference. Lonsdale's 2:15.86 is the most meaningful real data point in this event. The record still has 6+ seconds of real-world protection, but she's the swimmer with actual form here. Breaststroke 50 Breaststroke — NAG: 31.80 | Grace Koenig-Song (2024) Jordan Xanthos (14) is the clear standout in breaststroke. Her last-season LCM reference of 32.84 — set at Junior Nationals last July — is 3.27% above the record, and her projection of 32.91 is consistent with that baseline. In the 50 breast a 1+ second gap is real, but racing at Junior Nationals level is meaningful context. Anna Heumann (14) follows at 33.20 projected, with a 35.62 last-season LCM reference from a January meet. Emma Fouke (14) is third at 33.21 projected, with a 33.96 last-season LCM reference — the most aligned with her projection of the three. Xanthos leads this event clearly in both projection and real performance. The record has protection at this level, but she's the swimmer most worth tracking in breaststroke across the summer. 100 Breaststroke — NAG: 1:08.09 | Amanda Beard (1996) A 30-year-old record with a clear cushion over the current field. Jordan Xanthos leads at 1:01.54 SCY (1:10.31 projected), with a last-season LCM reference of 1:12.02 — nearly 4 seconds above the record in real competition. Payton Garnsey (14) follows at 1:10.70 projected, with a 1:13.26 last-season LCM reference. Marina Didenko (14) rounds out the group at 1:10.82 projected, with a 1:13.54 last-season LCM reference. Beard's record has lasted three decades with good reason. Last-season LCM times in the 1:12–1:13 range tell the story — the field has genuine ground to cover before this mark is under pressure. 200 Breaststroke — NAG: 2:25.75 | Amanda Beard (1996) Madeleine Szymanowski (14) and Ziva Liu (14) lead at nearly identical projections — 2:31.24 and 2:31.42 — both roughly 5.5 seconds above the record. Last-season LCM references of 2:36.49 and 2:37.56 confirm that gap is real. Marina Didenko rounds out the group at 2:32.71 projected, with a 2:40.68 last-season LCM reference. The record is protected. Szymanowski and Liu are closely matched and both improving — their competition within this group is the more relevant story this summer. Butterfly 50 Butterfly — NAG: 26.18 | Claire Curzan (2019) All three candidates project in the 28.28–28.45 range — roughly 8–9% above Curzan's mark — which is a substantial gap in a sprint event. Helen Manak (14) leads at 24.85 SCY (28.28 projected), with no last-season LCM reference available. Lizzie Anderson (14) follows at 24.98 SCY (28.43 projected), with a last-season LCM reference of 28.69 — her real LCM time is ahead of her own projection, indicating solid long course fly efficiency. Gianna Mattrey (14) rounds out the group at 25.00 SCY (28.45 projected), with a 28.85 last-season LCM reference. The record is not under pressure from this field. Anderson's long course conversion efficiency stands out within the group, but the gap to the record remains wide. 100 Butterfly — NAG: 58.61 | Claire Curzan (2019) Finola Whelehan projects to 59.22 — 0.61 seconds and about 1% above Curzan's record. Her last-season LCM reference of 1:01.16 puts her 2.55 seconds above the mark in real competition. That's a meaningful step in the 100 fly for one summer. Natalia Lesniewska and Helen Manak both project around 1:02, with last-season LCM references of 1:06.42 and 1:05.85 — both clearly off the pace in real terms. Whelehan is the only candidate with a projection in the vicinity of the record. The 2.55-second gap from her last-season LCM time to Curzan's mark is a realistic target to monitor, not a prediction. The record is protected; Whelehan is the name to watch. 200 Butterfly — NAG: 2:07.01 | Mary Meagher (1979) A record that has survived 47 years. Finola Whelehan projects to 2:10.03 — 3 seconds above the mark — but her last-season LCM reference of 2:29.92 from a May meet reflects very early-season long course 200 fly exposure, making this a developmental baseline rather than a competitive reference. Marina Didenko and Grace Gannon (13) project around 2:17, with last-season LCM references of 2:22.87 and 2:22.35 — more representative of real competitive level. Meagher's 1979 record is not under meaningful pressure from this field. A 3-second projected gap is real, and last-season LCM references in the 2:22–2:29 range confirm the distance. Individual Medley 200 IM — NAG: 2:12.53 | Teagan O'Dell (2021) Finola Whelehan projects to 2:12.98 — just 0.45 seconds and 0.34% above O'Dell's record on paper. Her last-season LCM reference of 2:19.61, however, is 7+ seconds above the mark — among the largest projection-to-reference gaps in her entire profile. Lauren Lonsdale is the more grounded candidate here: her last-season LCM time of 2:15.79 sits 3.26 seconds above the record, and her projection of 2:15.17 closely matches that baseline — a sign that her IM long course form is already well developed. Kate Allen rounds out the group at 2:16.01 projected, with a 2:21.01 last-season LCM reference. Lonsdale's 2:15.79 is the most credible real-world indicator in this event — she's been closer to the record than either other candidate in actual competition. Whelehan's SCY 200 IM is exceptional, but the LCM version still has a larger gap to close. 400 IM — NAG: 4:39.76 | Becca Mann (2012) Finola Whelehan projects to 4:42.76 — 3 seconds and 1.07% above the record — but her last-season LCM reference of 5:02.95 reveals just how early in her long course 400 IM development she currently is. Lauren Lonsdale is again the more grounded comparison: her last-season LCM time of 4:46.27 is actually faster than her current projection of 4:46.81, meaning her real long course 400 IM form is ahead of what conversion math would predict. Madison Suchecki rounds out the group at 4:47.67 projected, with a 4:57.74 last-season LCM reference. The record has real protection. Lonsdale's 4:46.27 last-season LCM time is the most credible real performance in this event — she's already been within 6.5 seconds of the record in actual competition. Overall Picture Finola Whelehan (14) is the standout performer in this dataset by SCY metrics, with projections that clip or approach several records. The consistent theme across her profile is a meaningful gap between her SCY form and her current LCM results — most pronounced in the 200 IM, 400 IM, 100 back, and 200 fly. The 2025–26 long course season is a test of how much of her winter improvement she can carry into 50-meter pools. The 200 free (0.98% projected gap, last-season LCM reference 3.55 seconds above the record) and 100 fly (1.04% projected gap, last-season LCM reference 2.55 seconds back) are the events where that test is most worth following. Lauren Lonsdale (14) is the more proven long course performer. Her last-season LCM times in the 400 free (4:15.61), 200 IM (2:15.79), 200 back (2:15.86), and 400 IM (4:46.27 — ahead of her own projection) are the most advanced real-world references in those respective events. Her LCM form and her projected times align closely, which is a sign of efficient long course conversion. Event-specific names: Jordan Xanthos leads the breaststroke field clearly, with a Junior Nationals LCM reference that puts her at the top of the real-performance picture. Zaryna Wardlay is worth noting in the 50 free for her LCM efficiency. And Lillie Dirito (13) in backstroke has two full summers remaining as a 13-14-year-old. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Last-season LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff (swimmer remains 13 or 14 as of 8/1/2026).

Data current as of April 22, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 12 or under as of 8/1/2026) The long course season is now underway, and this winter's short course results have already painted a compelling picture of where the Girls 11-12 LCM NAG records stand heading into the summer. The 11-12 class this cycle is deep and talented, with several swimmers projecting into competitive range of marks held by names like Claire Tuggle, Kayla Han, and Beth Botsford — some of which have stood for decades. Below is a look at each standing record, the current top candidates based on 2025–26 SCY performance, a classical conversion projection of what those times could translate to in long course, and each swimmer's last-season LCM reference time as a real-world baseline. The Record Holders & The Candidates 50 Freestyle — NAG: 26.21 | Missy Franklin (2008) Franklin's 2008 sprint mark has aged remarkably well. The top three candidates convert in the 28.15–28.25 range — roughly 2 seconds above the record — but the field is tight and fast. Adry Francis (12) leads at 24.64 SCY (28.15 projected), with a last-season LCM reference of 29.85 showing real improvement potential. Yara Tsybulina (12) follows at 24.69 SCY (28.21 projected), and already owns a 29.00 last-season LCM time — the closest any candidate in this event gets on actual swims. Morgan Wu (12) rounds out the group at 24.73 SCY (28.25 projected), with a last-season LCM reference of 29.47. Tsybulina's 29.00 last-season LCM time puts her within 2.79 of the record on actual swims. The record is safe, but this is a genuinely fast sprint field. 100 Freestyle — NAG: 56.87 | Lia Neal (2008) Another 2008 record that has proven durable. Amelia Alsina (12) leads at 52.99 SCY (1:00.42 projected), with a last-season LCM reference of 1:05.42 — meaning her projection is nearly 5 seconds ahead of where she's been in long course, leaving real uncertainty about how she translates. Madison Lord (12) follows at 53.43 SCY (1:00.91 projected), with a last-season LCM reference of 1:04.31 that shows better real-world long course speed. Yara Tsybulina is third at 53.49 SCY (1:00.97 projected), and her last-season LCM reference of 1:02.40 is the most advanced real baseline in this event — already sub-1:03. Lord and Tsybulina both have last-season LCM references meaningfully ahead of their projections — a strong sign of long course efficiency. The record still has a comfortable margin, but this event has legitimate depth. 200 Freestyle — NAG: 2:02.21 | Claire Tuggle (2017) Penelope Chao (12) projects to 2:06.78 LCM from her 1:51.33 SCY, with a last-season LCM reference of 2:13.40 — showing meaningful long course experience and a clear development arc. Vanessa Kuo (12) follows at 1:51.77 SCY (2:07.26 projected), though her 2:20.76 last-season LCM reference suggests her conversion may not yet reflect what she's capable of in long course. Amelia Alsina rounds out the group at 1:54.25 SCY (2:10.02 projected), with a last-season LCM reference of 2:20.63 also well behind her projection. Chao's 2:13 last-season LCM reference gives her the most credible long course baseline in this event. The record has nearly 5 seconds of protection, but her trajectory is the clearest. 400 Freestyle — NAG: 4:17.65 | Kayla Han (2021) A 2021 record with a meaningful cushion. Penelope Chao leads at 4:27.40 projected, with a last-season LCM reference of 4:39.98 — showing she's already been competitive at this distance in long course. Vanessa Delev (12) follows at 4:30.08 projected, with a last-season LCM reference of 4:41.94 confirming solid long course 400 free experience. Vanessa Kuo is third at 4:34.62 projected, though her last-season LCM reference of 4:53.48 from a May time trial suggests she's still building her long course distance form. Chao and Delev both have last-season LCM times in the 4:39–4:42 range, comfortably inside the 4:50 threshold. Neither is near Han's record yet, but both are moving in the right direction. 800 Freestyle — NAG: 8:50.58 | Kayla Han (2021) Penelope Chao leads at 9:08.86 projected — about 18 seconds above the record — with no prior LCM 800 reference available, meaning this summer may be among her first serious looks at the event in a 50-meter pool. Vanessa Kuo projects to 9:23.67, also with no prior LCM 800 reference. Emma Lynch (12) rounds out the group at 9:29.68 projected, and is the only candidate with a last-season LCM 800 reference of 10:02.25 — showing she's still early in her long course distance development despite a strong SCY baseline. The 800 free is largely uncharted territory for this field in long course. Chao's projection is the closest, but with no last-season LCM baseline to calibrate against, it's one to simply watch this summer. 1500 Freestyle — NAG: 16:48.12 | Bella Rongione (2012) Vanessa Kuo leads at 18:09.21 projected, with a last-season LCM reference of 18:53.83 — meaning she's already raced this event and is likely to improve significantly. Ziqi Sun (12) follows at 18:28.65 projected, with a last-season LCM time of 19:15.02 as a reference. Yara Tsybulina is third at 18:35.61 projected with no prior LCM 1500 reference available. Rongione's 2012 record is safely protected. Kuo's consistent presence across every distance free event makes her the swimmer to follow in this range heading into summer. 50 Backstroke — NAG: 29.36 | Maggie Wanezek (2018) Morgan Wu leads at 29.94 projected from her 26.43 SCY — within 0.58 of the record on paper. Her last-season LCM reference of 32.60, however, shows that her SCY form and LCM form are still meaningfully different, so the projection may be optimistic at this stage. Kyra Tan (12) follows at 30.83 projected, with a last-season LCM reference of 33.11. Yara Tsybulina is third at 30.88 projected, with a last-season LCM reference of 34.91 — also suggesting significant long course development ahead in backstroke. Wu's projection is the closest of any candidate in the entire dataset to a standing record. Her 32.60 last-season LCM time is the reality check. How much she closes that gap this summer is the key question. 100 Backstroke — NAG: 1:03.08 | Beth Botsford (1994) The oldest record in this dataset by over a decade — set in 1994 — and the most protected mark on the board. Morgan Wu leads at 1:04.58 projected from her 57.10 SCY, but her last-season LCM reference of 1:11.71 shows she's still far from converting that SCY form into long course results. Claire Liu (12) follows at 1:06.11 projected, with a last-season LCM reference of 1:11.07. Penelope Chao rounds out the group at 1:06.28 projected, with the most credible last-season LCM baseline at 1:08.54 — already inside the 1:09 barrier last summer. Botsford's 1994 record has seen 32 years of challengers. Chao's 1:08.54 last-season LCM time is the most meaningful number in this event — she's been the closest to the record of anyone in this field. 200 Backstroke — NAG: 2:15.17 | Elizabeth Beisel (2005) Penelope Chao leads at 2:20.07 projected, with a last-season LCM reference of 2:25.75 — showing consistent long course backstroke form and a credible development path. Vanessa Delev follows at 2:21.23 projected, with a last-season LCM reference of 2:27.53. Claire Liu rounds out the group at 2:22.06 projected, with a last-season LCM reference of 2:32.24 that places her further behind in real terms. Beisel's 2005 record has 5+ seconds of protection over the projected field. Chao's last-season LCM reference is the most advanced real baseline, and she looks like the swimmer most likely to make noise in this event. 50 Breaststroke — NAG: 32.96 | Zoe Skirboll (2017) Yan Zheng (12) leads at 34.60 projected, with a last-season LCM reference of 36.58 — showing she's been swimming this event in long course and improving. Lillian Rowold (12) follows at 35.09 projected, with a last-season LCM reference of 36.99. Reagan Walsh (12) rounds out the group at 35.57 projected, with a last-season LCM reference of 36.63 — the tightest gap between projection and last-season LCM of the three, suggesting solid long course breaststroke efficiency. The record has roughly 1.6–2.6 seconds of protection. All three candidates have last-season LCM times in the 36.5–37.0 range, confirming the conversion gap is real. 100 Breaststroke — NAG: 1:09.87 | Carly Geehr (1997) A 1997 record that has outlasted nearly three decades of challengers. Yan Zheng leads at 1:14.38 projected, with a last-season LCM reference of 1:18.97 — showing her conversion is ahead of her actual long course form at this stage. Lillian Rowold follows at 1:16.51 projected, with a last-season LCM reference of 1:20.64. Shelby Bigby (12) rounds out the group at 1:16.88 projected, with a last-season LCM reference of 1:20.45 nearly identical to Rowold's. The record is well protected at over 4 seconds above the top projection. Geehr's 1997 mark has proved remarkably durable — and this field still has ground to cover in real long course swims before it comes into view. 200 Breaststroke — NAG: 2:34.28 | Annie Zhu (2007) Yan Zheng leads at 2:43.67 projected, with a last-season LCM reference of 2:57.61 — confirming real development ahead in long course. Vanessa Kuo follows at 2:45.48 projected, with a last-season LCM reference of 2:57.17 from an April meet. Claire Liu rounds out the group at 2:45.52 projected with no prior LCM 200 breast reference available. Zhu's 2007 record has nearly 10 seconds of protection. Last-season LCM times in the 2:57 range confirm how much runway remains in this event. 50 Butterfly — NAG: 27.91 | Claire Curzan (2017) Morgan Wu leads at 28.89 projected, with a last-season LCM reference of 30.08 — about 1 second above her projection, suggesting she converts reasonably in fly. Claire Liu follows at 29.92 projected, with a last-season LCM reference of 32.18 — notably behind the projection, indicating real development potential in long course. Mia Douglas (12) rounds out the group at 30.04 projected, with a last-season LCM reference of 31.41. Wu's 28.89 projection is the closest to Curzan's record of any butterfly candidate in the dataset. Her last-season LCM reference of 30.08 suggests she translates reasonably well, and a sub-29 swim this summer is within reach. 100 Butterfly — NAG: 1:01.41 | Audrey Derivaux (2022) A recent record with some recency protection, but this event has genuine depth. Morgan Wu leads at 1:03.86 projected, with a last-season LCM reference of 1:07.46 — a clear sign of development ahead. Evyn Cain (12) follows at 1:05.76 projected, with a last-season LCM reference of 1:08.24 closely aligned with her projection. Vanessa Delev rounds out the group at 1:05.91 projected, with a last-season LCM reference of 1:07.80 — essentially matching her projection, a sign of strong long course butterfly efficiency. The record has about 2.5 seconds of protection over Wu's projection. Delev's last-season LCM time of 1:07.80 is the most credible baseline in this event, already showing she swims fly well in a 50-meter pool. 200 Butterfly — NAG: 2:15.02 | Cassidy Bayer (2012) Vanessa Delev leads at 2:24.72 projected, with a last-season LCM reference of 2:30.89. Morgan Wu follows at 2:25.10 projected, with a last-season LCM reference of 2:32.24. Penelope Chao rounds out the group at 2:25.55 projected, and her last-season LCM reference of 2:28.80 is the most advanced real mark in this event — ahead of both Delev and Wu in actual long course swims. The record has nearly 10 seconds of protection. Chao's 2:28.80 stands out as the most meaningful last-season LCM reference across all three candidates. 200 IM — NAG: 2:18.69 | Teagan O'Dell (2019) Penelope Chao leads at 2:24.29 projected, with a last-season LCM reference of 2:29.06 — a credible long course IM baseline showing she handles the four-stroke format well in a 50-meter pool. Claire Liu follows at 2:25.27 projected, with a last-season LCM reference of 2:30.59. Vanessa Delev rounds out the group at 2:26.72 projected, with a last-season LCM reference of 2:30.53 — nearly identical to Liu's. Three candidates projecting in the 2:24–2:27 range, all with last-season LCM times in the 2:29–2:30 window. The record has about 6 seconds of protection, but this is the deepest and most experienced IM field in the dataset. 400 IM — NAG: 4:50.70 | Kayla Han (2021) Penelope Chao leads at 5:03.21 projected, with a last-season LCM reference of 5:13.73 — showing meaningful 400 IM long course experience. Vanessa Kuo follows at 5:07.20 projected, though her last-season LCM reference of 5:37.31 from an April meet suggests limited 400 IM long course racing history. Vanessa Delev rounds out the group at 5:13.16 projected, with a last-season LCM reference of 5:20.26 — the most closely aligned with her projection, indicating solid conversion in this event. Han's 2021 record has over 12 seconds of cushion. Chao's 5:13 last-season LCM reference is the most relevant real benchmark, and Delev's close alignment between projection and last-season LCM time is an encouraging sign of long course readiness. Recurring Names & Overall Takeaways The Girls 11-12 LCM field this cycle features a compact group of swimmers who show up across a wide range of events: Penelope Chao (12) is the most complete swimmer in the dataset, appearing in the 200–800 free, 100–200 back, 200 fly, 200 IM, and 400 IM. Her last-season LCM references are the most credible real-world baselines across multiple events — particularly the 100 back (1:08.54), 200 back (2:25.75), and 200 IM (2:29.06). Morgan Wu (12) leads the sprint and butterfly picture, with projections in the 50 back, 50 fly, 100 fly, and 200 fly that are among the closest to standing records in the dataset. Her 50 back projection of 29.94 is within 0.58 of Wanezek's NAG on paper — the tightest gap in the entire dataset. Vanessa Delev (12) is a consistent presence across back, fly, and IM, with last-season LCM references that closely match her projections — a sign of efficient long course conversion. Yan Zheng (12) leads all three breaststroke events with strong SCY performances, though her last-season LCM references confirm the conversion gap in breast remains real. Yara Tsybulina (12) is the most credible sprint threat in the dataset, with a last-season LCM time of 1:02.40 in the 100 free already well ahead of her SCY-based projection — the kind of long course efficiency that makes her a name to watch once competition begins. No record appears on the verge of falling this cycle, but the 50 back (Wu), 100 back (Chao), and 50 fly (Wu) are the events where the gap between current ability and the standing mark is narrowest. The long course season will tell which swimmers close the gap between what their short course times suggest and what they can actually do in a 50-meter pool. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Prior LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff. ((swimmer remains 12 or under as of 8/1/2026))

Data current as of April 22, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 12 or under as of 8/1/2026) The long course season is now underway, and this winter's short course results have shaped a clear picture of where the Boys 11-12 LCM NAG records stand heading into the summer. The field this cycle has genuine depth, with several events featuring multiple swimmers projecting within striking range — and one record already sitting within a conversion margin that makes it worth circling on the calendar. A notable context note: several records in this dataset were set in 2025 by Ayden Tan and Sahiel Pai, meaning they carry strong recency protection. Those marks won't fall easily, but they're worth tracking as baselines for what this age group can achieve at its current ceiling. Below is a look at each standing record, the current top candidates based on 2025–26 SCY performance, a classical conversion projection, and each swimmer's last-season LCM reference time as a real-world baseline. The Record Holders & The Candidates 50 Freestyle — NAG: 24.95 | Ayden Tan (2025) Set just last summer, Tan's 50 free mark is fresh and well protected. Hunter Gumbayan (12) leads at 23.01 SCY (26.34 projected), with a last-season LCM reference of 28.41 — showing real development ahead before approaching the record. Maverick McMeeking (12) follows at 23.15 SCY (26.50 projected), with a last-season LCM reference of 27.49 that's the most advanced real sprint baseline in this event. Alexander Kovtounenko (12) rounds out the group at 23.22 SCY (26.57 projected), with a last-season LCM reference of 27.74. McMeeking's 27.49 last-season LCM time is the headline — he's already been within 2.54 of Tan's record on actual swims. The record is protected, but McMeeking is the one to watch once the pools open. 100 Freestyle — NAG: 54.91 | Ayden Tan (2025) Another 2025 Tan mark. Maverick McMeeking leads at 50.80 SCY (57.99 projected), with a last-season LCM reference of 59.52 — already sub-60 in long course, and the only candidate in this event with a last-season LCM time that credibly suggests sub-58 potential is coming. Jayson Clark (12) follows at 51.28 SCY (58.52 projected), with a last-season LCM reference of 1:01.00. Hunter Gumbayan rounds out the group at 51.34 SCY (58.59 projected), with a last-season LCM reference of 1:03.55 — notably behind both his projection and McMeeking's real baseline. McMeeking's 59.52 last-season LCM reference makes him the clearest real-world threat in this event. The record still has over 4 seconds of protection, but his trajectory is steep. 200 Freestyle — NAG: 1:59.72 | Winn Aung (2015) This is one of the most compelling events in the dataset. Hunter Gumbayan projects to 2:06.54 from his 1:51.12 SCY, with a last-season LCM reference of 2:10.60 — a real, credible long course 200 free baseline that puts him within 10.88 seconds of the record on actual swims. Maverick McMeeking follows at 1:51.91 SCY (2:07.42 projected), with a last-season LCM reference of 2:13.91. Jackson Gardner (12) is third at 1:52.44 SCY (2:08.01 projected), but his last-season LCM reference of 2:19.05 suggests he still has meaningful ground to cover in the 50-meter pool. Gumbayan's 2:10 last-season LCM time is the most advanced in this event, and his projection is the closest to the record. This is an event worth monitoring through the summer. 400 Freestyle — NAG: 4:12.52 | Matthew Hirschberger (2011) A 2011 record with a comfortable margin on paper, but Hunter Gumbayan projects to 4:26.62 and already has a last-season LCM time of 4:33.39 from last summer — the most significant last-season LCM baseline of any distance free candidate in the boys dataset. Adrian Adriano (12) follows at 4:32.69 projected, though his last-season LCM reference of 5:07.38 from a May state meet suggests he's still early in long course distance development. Jude Ciesielski (12) rounds out the group at 4:33.12 projected, with a last-season LCM reference of 4:51.15 showing better real-world alignment. Gumbayan's 4:33 last-season LCM reference is a genuine baseline. The record still has over 20 seconds of protection, but he's already in a range that puts the long-term trajectory of this mark in question. 800 Freestyle — NAG: 8:48.44 | Jude Burkhart (2024) Set in 2024, this is one of the more recently established records in the dataset. Hunter Gumbayan leads at 9:14.33 projected, with a last-season LCM reference of 9:39.65 — showing real long course 800 free experience and a meaningful development arc. Jackson Gardner follows at 9:15.51 projected with no prior LCM 800 reference, meaning this may be his first serious attempt at the event in long course. Bronson Jenner (12) rounds out the group at 9:17.51 projected, with a last-season LCM reference of 10:21.20 from last summer — the largest gap between projection and last-season LCM of any candidate in this event. Burkhart's 2024 record has roughly 26 seconds of protection over the top projection. Gumbayan's 9:39 last-season LCM time makes him the only candidate with credible long course 800 experience. 1500 Freestyle — NAG: 16:44.67 | Nicholas Caldwell (2006) A 2006 record with a substantial margin. Bronson Jenner leads at 17:37.88 projected, with a last-season LCM reference of 19:35.06 — a significant gap that indicates this will be his first real competitive attempt at the event in a 50-meter pool. Boardie Fouke (12) follows at 17:52.42 projected, with a last-season LCM reference of 18:40.91 more aligned with a real race performance. Alexey Zaitev (12) rounds out the group at 18:00.98 projected with no prior LCM 1500 reference available. The record is safely protected at nearly a minute above the top projection. Jenner's last-season LCM reference is the only real benchmark in this event, and it suggests the conversion projections may be optimistic for now. 50 Backstroke — NAG: 27.45 | Ronald Dalmacio (2017) Dalmacio holds three backstroke records in this dataset, and the 50 back has the smallest projected gap. Kallen McDowall (12) leads at 26.58 SCY (30.10 projected), with a last-season LCM reference of 35.08 — notably behind his projection, suggesting limited long course backstroke experience so far. Qianpu Ye (12) follows at 26.85 SCY (30.40 projected), with a last-season LCM reference of 34.16. Jayson Clark rounds out the group at 26.88 SCY (30.44 projected), with a last-season LCM reference of 32.61 — the most advanced last-season LCM backstroke baseline of the three. The record has roughly 2.7–3.0 seconds of protection over the field on projections alone. Clark's 32.61 last-season LCM time puts actual performance furthest from the record for now, but his SCY speed is the most aligned. 100 Backstroke — NAG: 59.43 | Ronald Dalmacio (2017) This is the most intriguing backstroke event in the dataset. James Hubbard (12) leads at 55.65 SCY (1:02.97 projected) — just 3.54 seconds above the record on paper. His last-season LCM reference of 1:11.43, however, reveals a substantial gap between his SCY form and his long course results, making the projection a genuine question mark. Alexey Zaitev follows at 57.74 SCY (1:05.29 projected), with a last-season LCM reference of 1:08.62 — a more grounded baseline that aligns better with his SCY-to-LCM conversion. Qianpu Ye rounds out the group at 57.97 SCY (1:05.55 projected), with a last-season LCM reference of 1:10.27. Hubbard's projection is the most eye-catching in the entire backstroke picture, but his last-season LCM time of 1:11 is the reality check. Zaitev's 1:08.62 last-season LCM reference is actually the most credible threat to the record on real swims. 200 Backstroke — NAG: 2:10.01 | Ronald Dalmacio (2017) The third and final Dalmacio backstroke record. James Hubbard leads at 2:02.28 SCY (2:18.13 projected), with a last-season LCM reference of 2:28.66 — a large gap between projection and real performance. Alexey Zaitev follows at 2:02.62 SCY (2:18.51 projected), with a last-season LCM reference of 2:25.72 — much more aligned with his projection and suggesting better long course efficiency. Jackson Gardner is third at 2:05.61 SCY (2:21.83 projected), with a last-season LCM reference of 2:29.62. Zaitev's 2:25.72 last-season LCM time puts him within 15 seconds of Dalmacio's record on actual swims — the most credible real threat across the backstroke trifecta. His prior-to-projection alignment is notably strong. 50 Breaststroke — NAG: 31.36 | Sahiel Pai (2025) Set in 2025 — one of the freshest marks in the dataset. Joe Kennedy (12) leads at 30.13 SCY (34.44 projected), with a last-season LCM reference of 41.65 from a May meet — suggesting very limited long course breaststroke experience to date. Jiaming Liu (12) follows at 30.26 SCY (34.59 projected), with a last-season LCM reference of 35.09 — the most grounded last-season LCM reference in this event, confirming he has actually raced it. August Le (12) rounds out the group at 30.29 SCY (34.62 projected), with a last-season LCM reference of 36.14. Liu's 35.09 last-season LCM time is the only meaningful competitive baseline here, already within 3.73 of Pai's record. The record is protected, but Liu is the swimmer with real long course breaststroke experience in this field. 100 Breaststroke — NAG: 1:07.97 | Sahiel Pai (2025) Another 2025 Pai mark with strong recency protection. Jiaming Liu leads at 1:04.83 SCY (1:13.96 projected), with a last-season LCM reference of 1:18.45 — showing he's raced the event but still has ground to cover. Ethan Zhang (12) follows at 1:05.12 SCY (1:14.28 projected), with a last-season LCM reference of 1:20.86. Qianpu Ye rounds out the group at 1:06.05 SCY (1:15.32 projected), with a last-season LCM reference of 1:18.78 closely aligned to Liu's real baseline. Pai's 2025 record has about 6 seconds of protection over the top projection. Liu and Ye both have last-season LCM times in the 1:18 range, confirming the field still has real development ahead. 200 Breaststroke — NAG: 2:27.88 | Ethan Dang (2014) Ethan Zhang leads at 2:22.22 SCY (2:41.86 projected), with a last-season LCM reference of 2:59.21 — a steep gap between projection and real performance, indicating his long course breaststroke is still developing significantly. Jiaming Liu follows at 2:23.36 SCY (2:43.13 projected), with a last-season LCM reference of 2:55.14. Jude Ciesielski rounds out the group at 2:23.84 SCY (2:43.66 projected), with a last-season LCM reference of 2:54.25 — the most aligned with his projection and the most advanced last-season LCM baseline in this event. The record has roughly 14 seconds of protection over the top projection. Last-season LCM times in the 2:54–2:59 range confirm the field is still well short of threatening Dang's 2014 mark. 50 Butterfly — NAG: 26.22 | Michael Andrew (2012) Archer Hougas (12) leads at 24.62 SCY (28.03 projected), with a last-season LCM reference of 29.41 — showing he's been in long course competition and is improving. Billy McCaslin (12) follows at 24.85 SCY (28.28 projected), with a last-season LCM reference of 30.76. Martin Kovac (12) rounds out the group at 25.00 SCY (28.45 projected), with a last-season LCM reference of 29.18 — the most competitive last-season LCM baseline of the three, already notably ahead of McCaslin's real reference. Andrew's 2012 record still has nearly 2 seconds of protection over the top projection. Kovac's 29.18 last-season LCM reference is the most credible real baseline in this event, ahead of where his projection might suggest. 100 Butterfly — NAG: 58.74 | Chas Morton (1983) The oldest record in the entire dataset — set in 1983 — and it may finally be facing its most serious challenge in years. Alexander Kovtounenko projects to 1:03.05 from his 55.54 SCY, with a last-season LCM reference of 1:05.70 — already within 6.96 of the record on real swims. Archer Hougas follows at 55.63 SCY (1:03.15 projected), with a last-season LCM reference of 1:07.00. Jackson Gardner rounds out the group at 56.76 SCY (1:04.40 projected), with a last-season LCM reference of 1:09.66 — notably further from the record in real swims. Morton's 1983 mark has been on the books for 43 years. Kovtounenko's 1:05.70 last-season LCM reference puts him within 7 seconds on actual competition swims — and his conversion math puts him at 1:03. This is the record to watch most closely this summer. 200 Butterfly — NAG: 2:11.07 | Dean Jones (2018) Jackson Gardner leads at 2:02.75 SCY (2:19.05 projected), with a last-season LCM reference of 2:34.63 — a significant gap suggesting he's still early in his long course 200 fly development. Jude Ciesielski follows at 2:05.19 SCY (2:21.76 projected), with a last-season LCM reference of 2:29.80 — better aligned. Alexander Kovtounenko rounds out the group at 2:05.82 SCY (2:22.46 projected), with a last-season LCM reference of 2:24.38 — the most advanced last-season LCM baseline in this event, already inside 2:25. Kovtounenko's 2:24.38 last-season LCM reference is the standout real number here — well ahead of both Gardner and Ciesielski on actual swims. The record still has 13 seconds of protection, but Kovtounenko's long course form is already noteworthy. 200 IM — NAG: 2:12.80 | Ayden Tan (2025) A 2025 record with strong recency protection. Qianpu Ye leads at 2:03.91 SCY (2:20.74 projected), with a last-season LCM reference of 2:30.58 — showing he's raced the event but still has ground to cover. Olin Woo (12) follows at 2:06.55 SCY (2:23.67 projected), with a last-season LCM reference of 2:40.35 — a large gap that suggests his SCY IM form hasn't yet translated to long course. Hunter Gumbayan rounds out the group at 2:07.31 SCY (2:24.51 projected), with a last-season LCM reference of 2:45.85 from a May meet — also well behind the projection. Tan's 2025 mark has about 8 seconds of protection over the top projection. Ye's 2:30.58 last-season LCM reference is the most relevant real benchmark, and the field still has meaningful long course IM development ahead. 400 IM — NAG: 4:42.54 | Richard Poplawski (2019) Jackson Gardner leads at 4:25.52 SCY (5:01.13 projected), with a last-season LCM reference of 5:26.72 — a large gap that indicates this summer may be his first serious long course 400 IM campaign. Jude Ciesielski follows at 4:27.33 SCY (5:03.14 projected) with no prior LCM 400 IM reference available. Grant Brown (12) rounds out the group at 4:31.46 SCY (5:07.72 projected), with a last-season LCM reference of 5:16.67 — the only last-season LCM 400 IM baseline in this group. Poplawski's 2019 record has over 18 seconds of protection. Brown's 5:16 last-season LCM reference is the only real benchmark, and the field still has significant long course IM development ahead before this record comes into view. Recurring Names & Overall Takeaways The Boys 11-12 LCM field this cycle is defined by several strong multi-event swimmers, with a genuine headline story in the butterfly events: Hunter Gumbayan (12) is the most complete swimmer in the dataset, appearing across all four freestyle events and the 200 IM. His last-season LCM references are the most advanced real baselines in the distance free picture — particularly his 2:10.60 in the 200 free and 4:33.39 in the 400 free. Alexander Kovtounenko (12) is the butterfly standout. His 1:05.70 last-season LCM reference in the 100 fly and 2:24.38 in the 200 fly are the most credible real-world performances of any butterfly candidate — and his SCY times project him squarely at Morton's 1983 100 fly record. Jackson Gardner (12) appears across the 200–800 free, 200 back, 100 fly, 200 fly, and 400 IM — a broad profile, though his last-season LCM references are generally further from his projections than other candidates, suggesting real long course development is still ahead. Maverick McMeeking (12) is the clearest sprint free threat, with a 27.49 last-season LCM time in the 50 free and a sub-60 last-season LCM reference in the 100 free — the most developed sprint long course résumé in the dataset. Alexey Zaitev (12) is the backstroke and distance free name to watch, with last-season LCM references in the 100 back (1:08.62) and 200 back (2:25.72) that are the most credible real threats to Dalmacio's 2017 marks. The event to watch most closely this summer is the 100 butterfly — Morton's 1983 record has been on the books for 43 years, and Kovtounenko's existing long course form suggests the gap between current ability and the record is narrower than the historical age of the mark implies. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Prior LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff. (swimmer remains 12 or under as of 8/1/2026)

Revision (May 2, 2026): This post has been updated to correct a math error in the 50 Freestyle section. Gabriel Brown's gap to the NAG record was misstated as 0.41 seconds; the correct gap is 2.41 seconds. Language in the body text and callout box has been updated accordingly. Data current as of April 20, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 10 or under as of 8/1/2026) The long course season is now underway, and this winter's short course results have already painted a compelling picture of where the Boys 10&Under NAG records stand. Several marks — some reaching back over a decade — are facing meaningful pressure from a strong and geographically diverse field of age-eligible swimmers. Below is a look at each standing record, the current top candidates based on 2025–26 SCY performance, and a classical conversion projection of what those times could translate to in long course. Projections are estimates, not predictions — but they're useful for calibrating just how close (or far) the records really are. The Record Holders & The Candidates 50 Freestyle — NAG: 27.42 | Winn Aung (2013) Aung's 2013 sprint marks have proven durable, but this cycle's field may be the most credible threat in years. Gabriel Brown (10) leads with a 25.76 SCY — projecting to 29.39 LCM — and already owns a real LCM best of 29.83 from last summer, the strongest real long course reference in this group, though still 2.41 seconds off the record. Robert Legg (10) is close behind at 25.99 SCY (29.65 projected), with a last season LCM best of 30.09 that confirms he converts well. Christian Briscoe (10) rounds out the group at 26.39 SCY (30.09 projected), showing solid improvement from his 31.20 LCM reference last spring. Brown's 29.83 real LCM best leads this group, and his 29.39 projection would be a meaningful personal best if he hits it. The record at 27.42 remains well protected, but with three competitive 10-year-olds in the 50 free, this is a group worth tracking as the long course season develops. 100 Freestyle — NAG: 1:00.67 | Winn Aung (2013) The 100 free tells a similar story. Gabriel Brown leads again at 55.01 SCY (1:02.66 projected), with a last season LCM best of 1:04.29 — already competitive at this age. Robert Legg follows at 56.47 SCY, projecting to 1:04.28, and his real LCM best of 1:04.82 is essentially in line with that projection. Isen Wolfe (10) rounds out the group at 56.99 SCY (1:04.86 projected), with a 1:06.14 last season LCM best showing continued progress. The record holds for now, but Brown's trajectory across the sprint and distance free events makes him the most compelling 10-under story on the boys' side this cycle. 200 Freestyle — NAG: 2:11.32 | Winn Aung (2013) This is the most compelling event in the dataset. Gabriel Brown projects to 2:12.83 LCM from his 1:56.78 SCY — just 1.51 seconds above the NAG record. His last season LCM best of 2:16.77 already shows strong long course form, and given the gap between his SCY level and what he's already done in the 50-meter pool, a sub-2:12 swim this summer is a realistic outcome. Robert Legg (2:00.49 SCY, 2:16.94 projected) and Isen Wolfe (2:03.89 SCY, 2:20.72 projected) are further back, though Wolfe's last season LCM best of 2:21.93 closely mirrors his projection. This is the record most likely to fall in 2026. Brown's conversion math puts him right on top of it, and his existing LCM best confirms he can perform in long course. 400 Freestyle — NAG: 4:36.22 | Adam Hinshaw (2004) The oldest record in this dataset by a wide margin — set in 2004 — and it may finally be in genuine jeopardy. Gabriel Brown projects to 4:35.80 LCM from his 5:09.02 SCY, which would be a record by 0.42 seconds. His last season LCM best of 4:54.47 shows there's still meaningful ground to cover in actual long course swimming, but the trajectory is steep. Robert Legg projects to 4:45.17 and Isen Wolfe to 4:48.77 — both well off the record, but showing healthy development with last season LCM bests in the 4:55–5:00 range. The conversion puts Brown just under the record, but his real LCM best of 4:54 suggests the projection may be optimistic. Still, a 22-year-old NAG finally has a legitimate challenger. 50 Backstroke — NAG: 30.82 | Ayden Tan (2023) One of three records Ayden Tan set in 2023, and arguably the most protected of the group given how recently it was established. Gabriel Brown leads at 29.06 SCY (32.86 projected), but his last season LCM best of 34.32 from an April meet last year indicates limited long course backstroke experience so far. Micah Pearson (10) follows at 29.49 SCY (33.33 projected), though his only LCM reference appears to be a 100 back time — suggesting his 50 back LCM history is minimal. Hoshi Aono (10) rounds out the group at 29.76 SCY (33.63 projected), with a 36.07 last season LCM best that leaves room to improve. All three candidates project 2+ seconds above the record. Safe for now — Tan's 2023 marks are proving resilient. 100 Backstroke — NAG: 1:07.40 | Ronald Dalmacio (2015) Gabriel Brown leads the 100 back field with a 1:01.12 SCY (1:09.04 projected) — just 1.64 seconds above the record on paper. His last season LCM best of 1:12.09 suggests the projection is ahead of where he's been in long course, but given his development arc across other events, meaningful improvement is plausible. Hoshi Aono (10) and Isen Wolfe (10) both project to the 1:12.67–1:12.73 range, with last season LCM bests of 1:16.85 and 1:16.14 respectively — a clear signal that both have been improving steadily in long course. Brown's projection is intriguing, but his real LCM baseline puts this record at arm's length for now. One to watch mid-summer. 50 Breaststroke — NAG: 35.65 | Matthew Limbacher (2011) A 2011 record that has held through several strong cycles. The current field converts in the 38.1–39.2 range — a gap that keeps it comfortable. George Xuan (10) leads at 33.45 SCY (38.13 projected), with a last season LCM best of 40.53, while Gabriel Brown is right behind at 33.74 SCY (38.45 projected) with a 40.48 last season LCM best. The two are nearly identical on paper. Zhecheng Zhu (10) rounds out the group at 34.40 SCY (39.18 projected), though his last season LCM best of 47.17 from a June league meet suggests very limited long course breaststroke experience to date. Record is well protected. Xuan and Brown are neck-and-neck and both improving, but a 2.5-second gap is real at this age. 100 Breaststroke — NAG: 1:18.56 | Ayden Tan (2023) Another 2023 Tan record, and like the 50 back, it still has a comfortable cushion. Gabriel Brown leads at 1:12.31 SCY (1:22.26 projected), with a last season LCM best of 1:28.80 — indicating his projection is well ahead of where he's been in long course breast. George Xuan follows at 1:12.86 SCY (1:22.87 projected) and already has a real LCM best of 1:28.76 — nearly identical to Brown's. Isen Wolfe (10) is third at 1:14.41 SCY (1:24.60 projected), with a 1:33.41 LCM reference that suggests he's still early in his long course breaststroke development. Tan's 2023 marks continue to hold. The field is developing but not yet threatening. 50 Butterfly — NAG: 29.91 | Carson Foster (2012) Carson Foster's 2012 mark is still standing, and the current field converts in the 31.5–32.6 range — about 1.6–2.7 seconds off on paper. Robert Legg leads at 27.77 SCY (31.52 projected), with a last season LCM best of 31.77 that is essentially in line with his conversion — a strong sign of LCM efficiency. Gabriel Brown follows at 28.21 SCY (32.01 projected), with a 32.84 last season LCM best showing improvement is coming. Christian Briscoe (10) rounds out the group at 28.77 SCY (32.63 projected), already having gone 32.90 in long course last summer. Legg's 31.77 real LCM best is the most telling number here — he's already been within 1.86 seconds of the record and converts cleanly. 100 Butterfly — NAG: 1:05.98 | Andrew Rogers (2015) A tight three-way race at the top of this event. Gabriel Brown leads at 1:01.91 SCY (1:10.12 projected), with a real LCM best of 1:10.33 — meaning his prior long course performance is already close to his projection, a strong sign. Robert Legg follows at 1:02.14 SCY (1:10.38 projected), and notably already has a 1:10.10 real LCM best — fractionally better than Brown's. Sean Northup (10) rounds out the group at 1:02.96 SCY (1:11.29 projected), with a 1:12.66 last season LCM best showing steady progress. Brown and Legg are essentially tied on projection, and both have real LCM bests right in the 1:10 range. The record has a 4-second cushion, but this event has two swimmers already operating at a high long course level. 200 IM — NAG: 2:27.38 | Ayden Tan (2023) The third and final Tan record in this dataset, and the most recently set. Gabriel Brown projects to 2:29.34 from his 2:11.66 SCY — just 1.96 seconds above the record on paper — making this, alongside the 200 free, one of the two most vulnerable records in the dataset. His last season LCM best of 2:35.03 suggests the projection is ahead of where he's been, but his development curve across all four strokes is steep. Robert Legg (2:17.08 SCY, 2:35.36 projected) and Isen Wolfe (2:19.39 SCY, 2:37.92 projected) are further back, with both showing healthy improvement from their last season LCM bests. Another record where Brown's conversion math puts him right on the doorstep. Whether his long course IM catches up to his SCY form this summer is the central question. Recurring Names & Overall Takeaways The Boys 10&Under field this cycle is defined by one dominant story and a genuinely competitive supporting cast: Gabriel Brown (10) appears in every single event in this dataset — an almost unprecedented level of cross-discipline breadth at this age. His projections in the 200 free, 400 free, and 200 IM all sit within striking distance of standing NAG records. Robert Legg (10) is the strongest challenger to Brown across the sprints and fly events, with a long course track record that closely mirrors his conversion projections — a sign of genuine LCM efficiency. Isen Wolfe (10) is a consistent mid-distance presence across free, back, breast, and IM, with last season LCM bests that largely align with his projections. George Xuan (10) and Christian Briscoe (10) are event-specific threats — Xuan in breaststroke, Briscoe in the sprints — both with developing long course résumés. The 200 free and 200 IM are the records to watch most closely this summer. Both involve Brown projecting within 2 seconds of marks that have stood since 2013 and 2023 respectively. Whether his short course form translates cleanly to long course — and how much he's improved since last summer — will be the defining question of the Boys 10&Under NAG landscape in 2026. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Age eligibility based on August 1, 2026 cutoff (swimmer remains 10 or under as of 8/1/2026).

Data current as of April 17, 2026 | Age eligibility cutoff: August 1, 2026 (swimmer remains 10 or under as of 8/1/2026) The long course season is now underway, and this winter's short course results have already painted a compelling picture of where the Girls 10&Under NAG records stand heading into the summer. Several marks — some dating back a decade — are drawing serious attention from a talented and deep crop of age-eligible swimmers. Below is a look at each standing record, the current top candidates based on 2025–26 SCY performance, and a classical conversion projection of what those times could translate to in long course. Projections are estimates, not predictions — but they're useful for calibrating just how close (or far) the records really are. The Record Holders & The Candidates 50 Freestyle — NAG: 28.15 | Adele Zyniewicz (2016) At over a decade old, this record has outlasted a lot of challengers. The current projection gap is real — the top three candidates convert in the 29.8–30.9 range — but Adeline Farrier (10) is worth watching closely. Her 26.17 SCY this season is genuinely fast for 10-and-under, and her last season LCM best of 32.19 leaves plenty of room to grow once she's swimming in a 50-meter pool. Lola Southard (10) is right behind at 26.43 SCY. Neither is converting near the record on paper, but both swimmers are moving quickly and long course efficiency tends to look different from these projections in practice. Record looks safe for now, but the class of 2026 bears watching if either swimmer takes a big LCM step forward. 100 Freestyle — NAG: 1:01.29 | Leah Hayes (2016) Another 2016 record, this one held by Leah Hayes, who also owns the 200 free NAG. The field here is strong. Adeline Farrier leads with a 57.80 SCY, projecting to 1:05.76 LCM — well off the record but showing genuine distance speed for her age. More interesting is Olivia Covey (10), whose last season real LCM best of 1:07.83 already suggests she translates well to long course. Her 59.10 SCY this season projects to 1:07.20, which aligns closely with what she's already done. Record remains comfortably protected, but Covey's LCM track record makes her one to watch once pools open. 200 Freestyle — NAG: 2:14.39 | Leah Hayes (2016) Hayes holds three records in this dataset, and the 200 free may be her most durable. The converted projections for the top three candidates (2:24–2:27) fall roughly 10–13 seconds short on paper. Addie Farrier leads the field at 2:07.54 SCY (projects to 2:24.77), with Olivia Covey (2:29.24 last season LCM best) and Hadley Wheeler (10) close behind. Wheeler, whose 2:09.83 SCY at the NT Texas Age Group Championship is her season-best, also showed meaningful improvement in LCM last summer. The gap is too large for a realistic challenge this cycle, but Covey's existing 2:29 LCM provides a genuine baseline. Here's the new section to insert — place it after the 200 Freestyle section and before 50 Backstroke: 400 Freestyle — NAG: 4:37.41 | Claire Tuggle (2015) Another 2015 record with a comfortable margin. The projected gap here is significant — all three candidates convert in the 5:02–5:07 range, leaving roughly 25–30 seconds between the field and Tuggle's mark. Adeline Farrier leads at 5:39.37 SCY (5:02.89 projected) with no last season LCM reference, meaning this may be her first real crack at the 400 free in long course. Hadley Wheeler (10) is close behind at 5:42.50 SCY (5:05.68 projected) and already has a real LCM best of 5:23.81 from last summer — the most meaningful baseline in this group. Reign Belzer (10) rounds out the field at 5:44.11 SCY (5:07.12 projected), with a last season LCM best of 5:13.05 that actually puts her ahead of her own conversion — a good sign for her long course efficiency at distance. The record is well protected for now. But Belzer's 5:13 real LCM swim is the most interesting data point — she's already well ahead of what the conversion math suggests. 50 Backstroke — NAG: 32.18 | Miriam Sheehan (2015) Sheehan's 2015 marks in the 50 and 100 back have proven remarkably resilient. The 50 back field is led by Reign Belzer (10), who has posted a 30.11 SCY — converting to a projected 34.02 LCM — alongside a last season LCM best of 36.61 that shows she still has ground to cover in the long course pool. Adeline Farrier is right there at 30.38 SCY (34.32 projected), and Annie Ma (10) rounds out the group at 30.98 SCY. Ma's LCM best of 39.46 is notably farther back than her SCY projection suggests, hinting at limited LCM experience so far. All three candidates convert 1.8–2.8 seconds above the record. Safe for now. 100 Backstroke — NAG: 1:09.36 | Miriam Sheehan (2015) This is one of the more interesting events on the list. Adeline Farrier leads with a 1:04.01 SCY (projecting 1:12.25), but her only last season LCM reference of 1:19.96 indicates she hasn't had much long course backstroke experience yet — meaning the projection may actually be conservative if she adjusts well. Hadley Wheeler (10) also deserves attention: her 1:05.63 SCY (1:14.05 projected) comes with a 1:19.85 last season LCM best, nearly identical to Farrier's. Reign Belzer (10) is third at 1:07.17 SCY, but she notably has a real LCM mark of 1:16.82 from last summer — already a bit ahead of where her projection might suggest. Record still has a comfortable margin, but this event has three swimmers developing in parallel. One to revisit mid-summer. 50 Breaststroke — NAG: 36.06 | Leah Hayes (2016) The Hayes trifecta continues. The 50 breast is where things get interesting in a different way: Sophia Hunter (10) and Iris Liu (9) both project in the 38.5–38.6 range from their SCY bests, but their last season LCM references tell very different stories. Liu already has a real LCM best of 40.24 — notably ahead of Hunter's 1:02.10 (which appears to be a 100 breast time listed as her only LCM reference, suggesting limited 50 breast LCM history). Emma Zhang (10) rounds out the group at 34.83 SCY (39.66 projected), with a 41.12 last season LCM best. Liu's 40.24 LCM best at age 9 is the most telling data point here — she's already swimming it and will have another full summer. 100 Breaststroke — NAG: 1:17.74 | Meghan Lynch (2014) The oldest record in this dataset, and perhaps the most fortified. Iris Liu (9) leads at 1:15.99 SCY (1:26.35 projected), followed closely by Emma Zhang (10) at 1:16.61 SCY. Notably, Zhang already owns a real LCM best of 1:26.25 — better than her own projection — which is a strong sign that her SCY-to-LCM conversion is efficient. Shay Kaplan (10) is third at 1:16.95 SCY with no last season LCM reference on record. The record has stood for over a decade for a reason. But Liu at 9 years old with a 1:15 SCY is a name to file away for the next cycle. 50 Butterfly — NAG: 29.48 | Miriam Sheehan (2015) Addie Farrier tops the fly events as well, with a 27.57 SCY that projects to 31.30 LCM — about 1.8 seconds above the record. Lola Southard (10) and Eva Rossetti (10) follow at 28.59 and 28.81 SCY respectively, projecting to 32.43 and 32.68. All three showed improvement from their last season LCM bests (33.66, 34.97, 34.14), which is an encouraging sign. None are projecting close to Sheehan's record, but the event is competitive within the age group. 100 Butterfly — NAG: 1:07.07 | Raquel Maldonado (2019) The most recently set record in the dataset, and it shows — this one has more cushion. Adeline Farrier leads at 1:02.14 SCY (1:10.38 projected), with Lola Southard and Reign Belzer both projecting around 1:12.4–1:12.6. Southard's last season LCM best of 1:35.11 suggests she's still very early in her long course 100 fly development. Belzer, by contrast, already has a 1:17.20 from last summer, making her the most experienced of the three in this event. Maldonado's 2019 mark still has meaningful protection. The field is developing, not threatening — yet. 200 IM — NAG: 2:28.70 | Kayla Han (2019) Another recent-era record that won't go quietly. Adeline Farrier leads with a 2:21.70 SCY (2:40.49 projected), followed by Hadley Wheeler (2:24.04 SCY, 2:43.08 projected) and Olivia Covey (2:24.92 SCY, 2:44.06 projected). Wheeler and Covey both have last season LCM IM bests in the 2:49–2:55 range, suggesting their projections are actually ahead of where they've been — a good sign for development, but also a reminder that conversion math doesn't always hold in the IM. The 200 IM record appears safe for 2026, but the three-way competition at the top of this event is worth following. Recurring Names & Overall Takeaways A few swimmers show up across multiple events, suggesting broad talent rather than specialist profiles: Adeline Farrier (10) appears in nearly every freestyle, backstroke, and butterfly event — arguably the most versatile 10-under swimmer in this dataset. Reign Belzer (10) surfaces in backstroke, breaststroke, and butterfly, with some of the most developed last season LCM reference times of any candidate. Olivia Covey (10) and Hadley Wheeler (10) are consistent mid-distance threats across free and IM events. Iris Liu (9) stands out as the youngest candidate on the list — appearing in both breaststroke events with times that are already competitive for her age group heading into next season. None of the records appear on the verge of falling based on projections alone, but several — particularly the 2015 Sheehan backstroke marks and the 2014 Lynch 100 breast — have been standing long enough that continued pressure from this crop will eventually tell. The long course season will reveal who converts well and who has even more in the tank than the short course numbers suggest. All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Age eligibility based on August 1, 2026 cutoff. (swimmer remains 10 or under as of 8/1/2026)
