After leading off Swim Atlanta’s 400 medley relay with a 45.06 split last night to become the fastest 17-year-old in history, Collin Holgerson delivered one of the most impressive doubles of the meet by firing off a 44.94 in the 100 back mere minutes after winning the 100 breast in 52.21.

His swim broke Will Modglin‘s 2022 meet record, and he becomes the fastest high schooler in history in this event despite only being a junior. Fittingly, SwimSwam recently highlighted Modglin’s ability  to excel in both the backstroke and breaststrokes after he swam a 50.9 in the 100 breast and 43.2 in the 100 back at Texas’ midseason invite. Out of high school, Modglin’s bests were 52.9 and 45.0—he is now the American record holder in the 100 back.

Holgerson climbs up to #3 in his age group rankings with this swim and joins an exclusive list of who 17-18 year old boys that have broken the 45 barrier:

All-Time Performers, Boys’ 17–18 100 Backstroke (SCY)

1. Ryan Murphy, 44.63 – 2014
2. Adam Chaney, 44.74 – 2021
3. Collin Holgerson, 44.94 — 2025
4. Owen McDonald, 45.00 – 2023
5. Will Modglin, 45.01 – 2022
6. Nicolas Albiero, 45.05 – 2018
7. Johnny Crush, 45.08 – 2024
8. Hudson Williams, 45.28 – 2024
9. Jack Conger, 45.32 – 2012
10. Austin Katz, 45.34 – 2017

Meanwhile, his time of 52.21 in the 100 breast ties Liam Bell—the former American record holder in the event—for #20 all time in the 17-18 age group.

Earlier in the meet, Holgerson swam a best time of 1:43.23 in the 200 IM to finish 2nd, dropping about 1.2 seconds. He also led off  SwimAtlanta’s 6th-place 200 medley relay in 21.02, a split that was equal to or faster than 12 leadoff legs in this relay at last year’s NCAA Championship meet. The Tennessee native, who attends and trains at the McCallie School in Chattanooga, Tennessee, has the 200 back on his schedule tomorrow. He is seeded 3rd behind Cal commits Baylor Stanton and Davis Jackson.

Holgerson is the #4 recruit in the high school class of 2027, and represented the US at the World Junior Championships over the summer. There, he took 10th in the 100 back in 55.21 and led off Team USA’s 400 medley relay in prelims with a time of 55.67. He will stay in state for college, as he has committed to swim for Tennessee next fall.
