Welcome to the first full finals session of the 2025 U.S. Open Championships. Tonight, we have a host of races with the top swimmers in the world racing each other as they try to end 2025 on a high note.
Schedule of Events
- 50 Back
- 400 Free
- 200 IM
- 50 Breast
- 50 Free
The meet will start with the 50 backstrokes. On the women’s side two of the best backstrokers in the world, Katharine Berkoff and Regan Smith, will be racing the 50 back with Berkoff, the American record holder in the event, leading the field with her top time from prelims coming in at 27.49
The men’s event will see 17-year-old Australian Henry Allan try to hold off some of the best backstrokers in the world in Hubert Kos and Shaine Casas.
The headline events of the session are the 400 freestyles, but for different reasons. On the women’s side, World Record holder Summer McIntosh earned the top spot by more than 11 seconds in prelims, swimming 4:00.68. Tonight, she will be chasing her own U.S. Open Meet record of 3:59.42, and Katie Ledecky‘s U.S. Open record of 3:56.82, but she will be in a field of her own.
The men’s race will be a different story. Leon Marchand is the best male swimmer in the world right now, and he comes in seeded 3rd behind training partners Luke Hobson and Carson Foster. Hobson swam the top time in prelims, touching in 3:47.56 to lead Foster’s 3:48.05 and Marchand’s 3:48.13. They will be joined by 16-year-old phenom Luka Mijatovic who sits less than two tenths back of Marchand at 3:48.30.
Where the women’s 400 freestyle will be a story of dominance, the men’s could be one of the closest races of the meet among some of the top swimmers in the world.
The 200 IM events see Kate Douglass and Hubert Kos as the top seeds. Douglass comes in nearly a second ahead of Canada’s Mary-Sophie Harvey and a little more than a second ahead of Alex Walsh. Kos, on the other hand, sits just two seconds ahead of Baylor Nelson, who is coming off the meet of his life at the Texas Hall of Fame Invite and half-a-second ahead of Indiana’s Owen McDonald, who also had a strong performance at midseasons.
The meet will end with the 50 breaststroke and 50 freestyle events. Ireland’s Mona McSharry is the top seed in the women’s 5- breaststroke, a tenth ahead of Ohio State’s Maria Ramos Najji from Spain. On the me’s side, South Africa’s Michael Houlie came in just five hundredths ahead of Van Mathias for the top spot.
The women’s 50 free will see Kate Douglass and Gretchen Walsh battle for the top spot from lanes 4 and 5, and the men’s 50 free final is missing a number of the top swimmers in the world including Ilya Kharun, Caeleb Dressel, and Santo Condorelli, but features Serbia’s Andrej Barna as the top seed just ahead of Jack Alexy and Chris Giuliano.

Jonny Kulow led the trio of ASU swimmers, touching in 21.87 for 4th, a tenth add form his best 21.73. Tolu Young was 7th in 22.06, a drop from his pre-meet best of 22.15 but just off his 21.92 in prelims, and Remi Fabiani was 8th in 22.09, exactly tying his premeet best, but off the 22.91 he swam in prelims
In the ‘B’ final, Caeleb Dressel swam 21.94, which would have tied with Alexy for 5th in the ‘A’ final.

Bro, Hubi decimated the competition. I thought he is going a 1:57 low, maybe a 1:56 mid.
I wouldn’t mind if he just went pro atp, it’s not like he is needed for the NCAA title.
For those who, like me, missed the A finals of 400 FS due to app…The replay is posted…W 400 starts at 46:45…M 400 starts at 1:09:36.
My plan for the meet is check in on live update comment thread on my phone, ignore the intermittent stream, and on my big screen watch another episode of Seventeen Moments of Spring (1973 version) English subtitled…ON YOUTUBE!! Then in the morning scroll through the previous night finals session to see the heats I’m interested in.
how did every single meet record go down lmfao
I had to double check that this wasn’t the first year for this meet or something, jeez
Can’t decide which is worse: Peacock showing all the drug commercials or Peacock showing all the C finals
The commercials obviously
The part that isn’t swimming of course
Hopefully some other commenter out of 413 also noticed this point, but I don’t have time tonight to read them all!
“Tolu Young was 7th in 22.06, a drop from his previous best of 22.15, and Remi FAbiani was 8th in 22.09, exactly tying his lifetime best.”
Tolu was :21.92PB in the prelims; Fabiani was :21.91PB in prelims.
For consistent prelim performance (remember these are all still NCAA swimmers, where there will only be 8 swimming in the final, with 9-16 scoring only off their prelim swims) it is fun to also note that with Kulow’s morning swim, ASU was :21.90, :21.91 and :21.92. Caeleb’s best on the day was :21.94.

Dear USA Swimming/NBC: dump Ambrose and any sidekick he has, and replace with Andy Jameson. Your viewers will thank you.
Darcy Revitt casually dropping 1.15s from her 50 pb since going to University/college in the US. I have been hearing of *lots* of top British juniors looking stateside and these successes will keep fuelling that – I imagine some at Aquatics GB will be fearing rather lacklustre performance centres in a few years time.
There’s nothing to suggest she couldn’t have made the same drop in a performance centre in the UK.
Other than the fact nobody else has done so? What sprinters have vastly improved at a NPC? *Freya Anderson* is the only NPC swimmer in the top 9 (nine) British female 50 freestylers, the rest are either in the US or schoolgirls at small local clubs. Like 2/3 of the top 20 are NPC swimmers.
Anna Hopkins???? Before she retired???
Fran Halsall before her???
Who came up with the idea of putting 3*50s in one session ?
Was it the new golf guy or Greg “Great Vibes” Meehan ?
The same people who put 3 100M races in one day and 3 200M races on one day
