Overview
- Gretchen Walsh won the women's 50m freestyle in 23.60 on Saturday, finishing 0.05 seconds slower than the 23.55 world record she set in June.
- Caeleb Dressel posted a 21.35 to win the men's 50m, his fastest time in four years, but he did not make the Pan Pacs roster because team selection used last year’s times.
- Nationals in Irvine functioned as a tune-up with swimmers using the meet to sharpen race execution and assess race shape ahead of the Pan Pacific Championships in two weeks.
- Distance and medley races produced notable results as Katie Grimes won the 1500m in 15:55.69, Ryan Erisman clocked 7:43.53 in the 800m to become the second-fastest American ever, and Maximus Williamson took the men's 200 IM in 1:56.40.
- The recent sprint arms race has been rapid: Kate Douglass briefly held the 50m world mark at 23.59 before Walsh lowered it to 23.55 in late June, highlighting a deep Virginia training group and a tight U.S. rivalry heading into international competition.
