Shaine Casas Rockets to #7 Performer Of All-Time With 1:55.24 200 IM


So, as we all know by now, Shaine Casas is good. 

After going 50.40 in the 100 fly, Casas went on to swim the 200 IM, where he crushed his previous best time of 1:56.70 and proceeded to go 1:55.24. That makes him the third-fastest American of all time behind Michael Phelps and Ryan Lochte and the seventh-fastest overall performer of all time.

Casas’ time was just 0.02 seconds off of Leon Marchand‘s 1:55.22 that won gold at the World Championships this year.

All-Time Top Performers, Men’s 200 IM:

  1. Ryan Lochte, United States — 1:54.00 (2011)
  2. Michael Phelps, United States — 1:54.16 (2011)
  3. Wang Shun, China — 1:55.00 (2021)
  4. Kosuke Hagino, Japan — 1:55.07 (2016)
  5. Laszlo Cseh, Hungary — 1:55.18 (2009)
  6. Leon Marchand, France — 1:55.22 (2022)
  7. Shaine Casas, United States — 1:55.24 (2022)

For the beginning of the race, Casas was actually ahead of Ryan Lochte‘s world record pace, flipping in 53.37 on his first 100 compared to Lochte’s 53.48. However, Lochte outsplit Casas by a significant margin on his back half, especially on his freestyle leg.

Shaine Casas, 2022 National Championships Ryan Lochte, 2011 World Championships (World Record)
Fly 24.30 24.89
Back 29.07 28.59
Breast 33.37 33.03
Free 28.50 27.49
Total 1:55.24 1:54.00

With Casas getting into the 1:55-point range, the men’s 200 IM at the 2024 Olympics trials is going to be extremely competitive, with Carson Foster being the Worlds silver medalist with a personal best time of 1:55.71 and Michael Andrew having a best time of 1:55.26.

It’s clearly been established that Casas’ best events are the 100 fly and 200 IM. That might present an issue for him in 2024, as the men’s 100 fly semifinals and 200 IM finals are going to be back-to-back events at both the Olympic trials and Olympic games.

The battle for Olympic gold medal will be epic in Paris. Eight guys by 71 hundredths. Here is their current PB.
1. 1:55.00 Wang Shun (CHN) in 2021
2. 1:55.22 Léon Marchand (FRA) in 2022
3. 1:55.24 Shaine Casas (USA) in 2022
4. 1:55.26 Michael Andrew (USA) in 2021
5. 1.55:28 Duncan Scott (GBR) in 2021
6. 1:55.40 Chase Kalisz (USA) in 2018
7. 1:55.55 Daiya Seto (JPN) in 2020
8. 1:55.71 Carson Foster (USA) in 2022

With 4 swimmers under 1:56 actually, the US Olympic trials will be fun to look at.

I think Wang Shun had his fastest swim, don’t see him going faster than 1:56 anymore

With him going 1:59 in prelims and 2:01 in semi’s at Worlds this year, it does make you wonder what stage in his career he might be in

I wouldn’t look too much into it. The whole Chinese team was not at their best at this Worlds because their taper got messed up by the weird scheduling and I think their original plan was to focus on Asian Games like Australia was doing for CG. I would expect them to be back in full force at the next Worlds or at least by the Olympics.

The 200 IM is a race with a history of close finishes at OTs. More on the women’s side but Phelps and Lochte went stroke for stroke too.

Two years away from 2024 and Carson, Shane and Michael are close competitors.

The difference is not even one stroke.

They better practice their finishes. No gliding or lifting the head.

Yeah claims he’s taking a year off from the event when he could have had a good shot at worlds and now he looks more likely to never qualify for a worlds or Olympic team again.

He will have to stick to 50 Free now that there is a clash anyway.

It seemed like we got so little from Casas at worlds, both in number of events and caliber of what he did. It felt like even more of a waste than Douglass on the women’s side, since Douglass is clear second behind Walsh at 200 medley while Casas has so much wiry ability a huge jump in this event was inevitable. He obviously believed that himself, if not satisfied with 1:55.2.

I hope he is smart enough to make this his primary event. But for whatever reason these guys stubbornly insist on the sprints. It was very weird to watch an American swimming an excellent time in 200 medley and not being forced to project 30+ additional seconds as soon… Read more »

So Shaine only made the WC team in maybe his 3rd or 4th best event, that’s some talent.

Really fast times by Casas this summer, but I am still looking for him to deliver when it matters most.
