Texas transfer Rex Maurer swam to an American Record in the men’s 500 freestyle, posting a 4:04.45 in his win on Wednesday night. Maurer broke the previous record of a 4:06.32 set by Florida’s Kieran Smith at 2020 SECs and 2021 NCAAs.

Note: Carson Foster went a 4:05.81 earlier tonight but we are searching for splits. That race was also considered an “unofficial” record.

Split Comparison:

Maurer also moves up to become the #2 performer all-time, sitting only behind Leon Marchand who swam a 4:02.31 to win the event at 2024 NCAAs. Maurer notably swam the 500 free at NCAAs this past March, finishing 31st in a 4:16.69. Maurer spent last season as a first-year with Stanford and has since transferred to Texas.

In addition to a new American Record, Maurer also swam to a Texas record. The previous school record stood at a 4:06.93 that Luke Hobson posted at 2024 NCAAs. Hobson was 4th tonight in a 4:12.92.
