Ilya Kharun swims history’s fastest 50-yard butterfly in 19.39
Arizona State’s Ilya Kharun produced the standout performance of a quadruple dual meet involving Arizona, USC and UCLA, swimming the fastest 50-yard butterfly in history in 19.39. The swim improved Kharun’s own unofficial 19.43 from an ASU practice and lowered the official benchmark of 19.56, set by Hubert Kos in the opening 50 of his 100 fly final at the 2026 NCAA Championships. It was also six-tenths faster than Kharun’s previous official best of 19.94, recorded in October 2024.
Kharun won two other individual events for the Sun Devils. His 18.50 in the 50 freestyle and 1:39.62 in the 200 butterfly were both the fastest times in the United States this season, with Kharun the only swimmer under 1:40 in the 200 fly. In the team results, ASU’s men and women defeated USC, while the ASU women also beat UCLA for the first time since 2007. Arizona’s men and USC’s women won their respective dual meets, and Arizona’s women defeated UCLA; Arizona State and Arizona, along with USC and UCLA, were not scored against each other.
The ASU women also swept all four relays. Albane Cachot won the 50 freestyle in 21.77 and the 100 freestyle in 46.74, a lifetime best and her first time under 47 seconds. Miriam Sheehan added victories in the 100 butterfly and 100 backstroke, setting personal bests of 51.46 and 51.30. Other notable winners included USC’s Minna Abraham in the 200 freestyle and 200 IM, and Arizona’s Kelsey Wasikowski, who broke one minute in the 100 breaststroke for the first time with 59.59.
