Shaine Casas swam to a personal best time in the 400 IM on Friday night, posting a 3:34.09 in the 400 IM. That time makes him the #5 performer all-time in the event as well, sitting right behind fellow Texas-based Carson Foster.

Top 5 Performers Men’s 400 IM

  1. Leon Marchand, 3:28.82
  2. Hugo Gonzalez, 3:32.88
  3. Chase Kalisz, 3:33.42
  4. Carson Foster, 3:33.79
  5. Shaine Casas, 3:34.09

Casas had a previous best time of a 3:38.22 that he swam back in October 2020 back when he was at Texas A&M. He swam the race in his own heat tonight as a member of the Texas pro group.

Casas arrived at Texas in 2022 while the team was under Eddie Reese. He stayed for the coaching change this past summer as well as Bob Bowman arrived from Arizona State.

Already seeing success this year under Bowman, Casas won the SC World Championship title last month in the 200 IM. He also helped the US to numerous gold medals at the relay level. The meet was a huge bounce back after he missed the final of the 200 IM at the 2024 Paris Olympics, finishing 9th in semifinals.

He looked great (how can a 3:34 not look great), but the most promising part about that swim for Shaine’s summer was the big smile at the end.

Happy, confident, enjoying doing the work.

If Shaine does a 2 fly over 2 back tomorrow, things could get interesting…

Tried to hand time using an online stopwatch so these are very rough:

#1 00:21.893 00:21.893
#2 00:25.823 00:47.716
#3 00:27.985 01:15.701
#4 00:27.689 01:43.390
#5 00:30.054 02:13.444
#6 00:30.048 02:43.492
#7 00:26.352 03:09.844
#8 00:24.073 03.33.917

Scoreboard said 24.21 on the last 50 so using that instead of what I got would result in 3:34.05

Five of the six fastest ever now coached by Bob including Rex Maurer. That has to be a first for a single event in history.

Is David Schlicht 6th? Also – still super impressive but Kalisz wasn’t coached by Bob when he went his yards PB

I believe Chase had his huge drop in yards when he came back to UGA after training with Bob for Rio. Still, good point that he was at UGA at the time he went his SCY PB.
