Florida junior Josh Liendo won his second consecutive NCAA title in the men’s 100-yard butterfly on Friday, clocking a time of 43.06. That time is a 0.01 second improvement off his best time, and it is now the second-fastest time ever in the event. The only performance faster than the Canadian’s swim is Caeleb Dressel‘s NCAA record time of 42.80.
In the same race, Arizona State sophomore Ilya Kharun clocked a best time of 43.49 to finish second and rank as the fourth-fastest performer of all-time, while Georgia redshirt senior Luca Urlando improved upon his best time to finish third and rank fifth in history.
All-Time Top Performers, Men’s 100-Yard Butterfly:
- Caeleb Dressel, Florida — 42.80 (2018)
- Josh Liendo, Florida — 43.06 (2025)
- Youssef Ramadan, Virginia Tech — 43.15 (2023)
- Ilya Kharun, Arizona State — 43.43 (2025)
- Luca Urlando, Georgia — 43.49 (2025)
Although Liendo still has yet to catch Dressel’s record, he has now been faster than Dressel’s second-fastest performance time of 43.58 on six different instances. Liendo has now been 43.06, 43.07, 43.23, 43.30, 43.40 and 43.49 all on separate occasions, holding five of the seven fastest performances of all-time in the 100 fly.
There’s still a gap between Liendo and Dressel on both halves of their respective personal bests, as Dressel is 0.14 seconds faster than Liendo on his front half and 0.12 seconds faster on his back half.
Split Comparison:
| Josh Liendo, 2025 NCAA Championships | Caeleb Dressel, 2018 NCAA championships (NCAA record) | |
| 50y | 20.13 | 19.99 |
| 100y | 22.93 | 22.81 |
| Total | 43.06 | 42.80 |
Liendo will still have one more season to take down Dressel’s record in the 100 fly. But for now, at the 2025 NCAA Championships, he has the 100 free left to race, where he is the two-time defending champion and top seed. Earlier this meet, he finished second in the 50 free (18.23).
Florida legends. Is Dressel back in training at UF this year? It kind of makes sense he might wait until the college season is over when things are more laidback.
Dressel is the greatest male college athlete, in any sport, of the 2010s. For his records to survive 6 years in SWIMMING, including onslaughts by two of the most incredible sprint talents we have ever seen, is so ridiculously impressive. I do think Liendo cracks this one at some point next year.
You’d have to disregard quite a many athletes for this to be true….this makes me wonder if black swimmers are setting records in swimming will their efforts all of a sudden degrade the value of the sport in many people’s minds…?
