Ben Armbruster broke the Pro Swim Series record in the men’s 50 fly on night three of the U.S. Summer Championships, throwing down a 23.00 to slide under the record line en route to claiming the championship title.

The Australian shaved .05 off of his former best time (23.05), set back in 2023, and took .09 off of the Series record. The previous record was a 23.09, which was posted earlier this season by Ilya Kharun at the Pro Swim Series – Fort Lauderdale in May.

Armbruster won by a decent margin tonight in Irvine, racing into the wall .28 ahead of runner-up Caeleb Dressel to defeat the American record holder.

Prior to tonight’s performance, the fastest he had been in this event since April 2023 was 23.08; he swam that time twice over the past two years, most recently at the 2025 Australian Swimming Trials in June.

Armbruster’s record-setting swim puts him at #15 on the ranking of top times in the world this season, tied with Stergios Bilas of Greece. Armbruster was 2nd in this event at the Australian Swimming Trials earlier this summer, but did not compete at the World Championships in Singapore. His time of 23.00 would have landed him solidly in the semifinals of the 50 fly.

Armbruster has posted a series of strong performances at the U.S. Summer Championships so far. Earlier in the meet, he won the 100 fly in 50.91, logging a new lifetime best, and took 4th in the 50 free in 22.10.
