Day 4 Prelims Heat Sheet
It’s the final day of the 2025 U.S. Open, featuring an exciting slew of events including the 50 butterfly, 200 backstroke, 200 breaststroke, 200 butterfly, and 100 freestyle. In addition, the 800 freestyle is set to kick-off at 5 PM tonight as the foreword to the final session of the meet.
After setting a new meet record in the 100 butterfly, Gretchen Walsh will be back in the pool for the 50 butterfly and 100 freestyle. In the 50 butterfly, she leads the field by over a second, while in the 100 freestyle, she will face-off against teammate Kate Douglass and Simone Manuel. Douglass is also swimming multiple events on the final day, with an entry in her signature 200 breaststroke event.
Summer McIntosh and Regan Smith are set to throw down in the 200 butterfly as the 1st and 2nd seeds. Following a strong performance in the 400 freestyle, McIntosh should be on World Record watch here. Smith will have a busy schedule as she is also the top seed in the 200 backstroke.
On the men’s side, there should be a great battle in the 200 butterfly between Olympic Champion Leon Marchand and Canadian star Ilya Kharun. The two swimmers are currently seeded 1-2 in the event, and will likely see each other tonight. Hubert Kos, like the aforementioned Smith, will also contest the 200 back/200 butterfly double, coming in as the top seed in the 200 back.
With the men’s freestyle sprints being one of the most consistent events across the meet, the 100 freestyle is expected to hold plenty of excitement as well, with Jack Alexy, Chris Guiliano, and Patrick Sammon holding down the top 3 seeds. Guiliano in particular has been swimming extremely well this weekend, having taken down meet records in both the 50 and 200 freestyle.

As expected, top seed Gretchen Walsh held down the fort in the women’s 50 butterfly, cruising to the top spot in the final with a time of 25.43 to lead the field by well over a second. Behind her, 23-year-old Natalie Kan posted the 2nd-fastest time of the morning from heat 2, swimming to the wall in 26.79, with Canadian star Mary-Sophie Harvey just behind in 26.81.
The top 10 swimmers in the event all finished under the 27-second mark this morning, with only .2 separating places 2-10. With that, there was a tie for 8th overall between Miriam Sheehan and Leah Shackley. The pair will swim-off for the final spot in the A-final pending scratches.

Condorelli dropped 1.4 seconds off of his seed time en route to qualifying 3rd in 23.42, while Dressel posted a solid 23.45. Dressel was 23.28 in August at the Pro Championships, his best time last season, so that will serve as a great benchmark for his finals swim.

It was a slightly slower-than-usual prelims of the women’s 200 backstroke, where many of the top swimmers did what was necessary to make it back for a second swim. Phoebe Bacon was the only swimmer under 2:10 in prelims, swimming a time of 2:09.59 to take the top seed. Regan Smith, the American Record holder in this event, looked relaxed as she cruised to a 2:11.47 ahead of her 200 fly prelim later in the session. 16-year-old Sadie Buckley was the youngest swimmer into the A-final, qualifying 3rd in 2:13.20 just aheadof Erika Pelaez (2:13.42).
Notably, Leah Shackley finished 5th here coming-off of her 50 butterfly prelim less than an hour before. She is set to have a swim-off for the A-final of the 50 butterfly, but she could elect to focus on just the 200 backstroke. UCLA’s Rosie Murphy continued her strong showing at this competition, finishing 6th this morning in 2:13.74, only .02 off of her personal best.

- Cornelius Jahn (OSU) – 2:00.64
Hungarian star Hubert Kos was in-control from start-to-finish in the final heat to take the top spot in tonight’s 200 backstroke final with a 1:58.56. In his heat, Kos led Florida’s Kieran Smith, who ended up qualifying 4th for the final in 1:59.90. It was actually heat 2 of the event that proved to be most competitive, producing 3 of the top 5 qualifiers for the final. Canadian Blake Tierney led that heat in 1:59.24 to end up 2nd overall behind Kos. He managed to get into the wall just ahead of Jt Ewing (1:59.42) and Tommy Hagar (1:59.94).
Notably, 2nd seed Jack Aikins, 4th seed Daniel Diehl, and 5th seed David King all missed out on the A-final. Of those swimmers, Diehl was the highest finisher, coming in 10th with a time of 2:00.84 to get lane 5 in tonight’s B-final. Aikins will also swim in the B-final after placing 14th this morning in 2:01.98. King ended up placing 18th overall for a swim in the C-final tonight (2:03.35).
WOMEN’S 200 Breaststroke – Prelims

- U.S. Open Record: 2:19.30 – Kate Douglass, USA (2024)

- Alex Walsh (NYAC) – 2:28.80
- Emily Lundgren (WSU) – 2:31.66
- Grace Rabb (FLOR) – 2:32.86
Top seed Kate Douglass looked smooth throughout her 200 breaststroke prelims swim ahead of her upcoming 100 freestyle prelim. Douglass touched the wall in a time 2:27.08 to lead the field this morning. Watch for Douglass to challenge her own meet record of 2:21.87 in finals. Tennessee’s Mona McSharry qualified 2nd for the final in 2:27.47. McSharry, the 2024 Olympic bronze medalist in the 100 breaststroke, has traditionally shifted away from the 200 meter distance, so it will be interesting to see what time she could throw down tonight. Tara Kinder (2:27.55), Alexanne Lepage (2:27.92), Aliz Kalmar (2:28.71), and Alex Walsh (2:28.80) also finished under 2:29, which could make the race in finals interesting.
48-year-old Gabrielle Rose was slightly off of her best time but managed to place 13th overall this morning to earn a lane in the B-final in 2:34.62.

There weren’t many major misses in the men’s 200 breaststroke, with the top seeds making it through to the final. Indiana’s Noah Cakir had a great showing this morning, winning his heat in a best time of 2:12.01 en route to taking the top seed for the final. Cakir also dropped time in the 100 breaststroke earlier in the meet. Aj Pouch was relaxed in his swim to touch in 2:12.50 for the 2nd seed in the final. Nate Germonprez also saw a 1 second drop off of his seed time, touching in 2:13.10 for 3rd overall.
American Josh Matheny was slightly off of his best time with a 2:13.49, but should be in the conversation tonight as a threat for first place.

Following her 200 freestyle victory last night in which she posted her fastest time since 2019, Simone Manuel had a strong 100 freestyle prelim en route to claiming the top seed for finals. Manuel won her heat in a time of 53.87, which is actually only .04 off of her time from last summer’s US National Championships (52.83). Finishing 2nd was Gretchen Walsh off of her 50 butterfly double as the Virginia swimmer posted a time of 53.93. Her teammate Kate Douglass also had a good showing off of a double with the 200 breaststroke prelims, touching in 54.22 for the 3rd seed into finals.
Coming off an ankle injury a few weeks ago, 4th seed Erin Gemmell added 2 seconds to her seed time to finish in 55.65 this morning, good for 15th overall and a swim in the B-final.
MEN’S 100 Freestyle – Prelims
- World Record: 46.40 – Pan Zhanle, China (2024)
- U.S. Open Record: 46.99 – Jack Alexy, USA (2025)

Top 8 Qualifiers:

- Jonny Kulow (UN-AZ) – 48.09
- Kaii Winkler (NCS) – 48.17

- Matt King (ISC) – 48.35
- Brendan Whitfield (VT) – 48.44
- Remi Fabiani (UN-AZ) – 48.80
The men’s 100 freestyle prelims lived up to expectations, with the meet record nearly going down 2 times within 2 heats. Building off of his strong performances this week, Chris Guiliano led heat 6, stopping the clock in 47.70 to break the Texas pool record and come within .01 of Zach Apple’s 2019 meet record of 47.69. At that point, however, it was Jack Alexy who stepped onto the blocks and made the record his own with a 47.66 performance in the next heat, setting up for a great battle in finals.
All 8 of the swimmers in the A-final broke 49 seconds this morning. Jonny Kulow (48.09) and Kaii Winkler (48.17) also posted times in the 48-low zone, while Partick Sammon and Matt King were just behind at 48.3. Notably, Jack Aikins and David King were both no shows for their heats following the 200 backstroke, as was Hunter Armstrong.
WOMEN’S 200 Butterfly – Prelims
- World Record: 2:01.81 – Liu Zige, China (2009)
- U.S. Open Record: 2:03.87 – Regan Smith, USA (2023)
- U.S. Open Meet Record: 2:06.72 – Regan Smith, USA (2023)
Top 8 Qualifiers:
- Summer McIntosh (TXLA) – 2:07.04
- Regan Smith (TXLA) – 2:09.62
- Alex Shackell (CSC-IN) – 2:10.22
- Lindsay Looney (TXLA) – 2:11.66

- Annemarie Vlaic (SMU) – 2:14.91
- Deniz Ertan (UN-AZ) – 2:15.06
- Lainy Kruger (FLOR) – 2:15.25
Summer McIntosh easily claimed the top spot in tonight’s 200 butterfly final with a relaxed stroke en route to a time of 2:07.04. Tonight, McIntosh will only be contesting the 200 fly and foregoing the 800 freestyle, which means she could drop something special. Coming-off the 200 backstroke, Regan Smith also posted a controlled swim with a time of 2:09.62, a half second ahead of fellow American Alex Shackell (2:10.22). Lindsay Looney was the only other swimmer in the field under 2:12, as she swam a time of 2:11.66. It should fall between these 4 swimmers tonight as they battle for the 3 podium spots.
MEN’S 200 Butterfly – Prelims
- World Record: 1:50.34 – Kristóf Milák, Hungary (2022)
- U.S. Open Record: 1:52.20 – Michael Phelps, USA (2008)
- U.S. Open Meet Record: 1:54.66 – Ilya Kharun, Canada (2023)
Top 8 Qualifiers:
- Hubert Kos (UN-ST) – 1:56.56
- Ilya Kharun (UN-AZ) – 1:57.14
- Cooper Lucas (TEX) – 1:57.89
- Leon Marchand (TXLA) – 1:57.97
- Gabriel Jett (CAL) – 1:58.14
- Bjoern Kammann (TNAQ) – 1:58.44
- Aaron Shackell (IU) – 1:58.71
- Jordi Vilchez (OSU) – 1:59.20
Like the aforementioned Regan Smith, Hubert Kos also handled a tough 200 butterfly/200 backstroke double with poise, taking the top spot in a time of 1:56.56 as the only swimmer under 1:57. That should be a different story tonight, as the finals field is set to feature Ilya Kharun and Leon Marchand. Kharun was 1:57.14 for 2nd this morning, while Marchand posted a 1:57.97 to claim 4th overall. Texas’ Cooper Lucas had a great performance in prelims to finish 3rd, dropping .6 seconds off of his best time to touch in 1:57.89.
Hot take:
100 fly ncaas will be the most stacked field in history i mean liendo will probably break the record and we will probably see other people go under 43 like ilya and urlando and heilman
My hot take:
Alexy 46.80 tonight.
Alexy usually swims slower in finals
That’s why my take is so hot.
not really , check last summer finals time
“Not really” isn’t the right phrase, because historically, it was every time. You should say hopefully, “not anymore”, after last summer
46.81 Semi 46.92 final
(46.92 is still fast as hell but it dosnt disprove my comment)
My hot take:.
Douglas will win 100 free
Lukewarm take
Oh that would be great for her
Be patient his time will come
The standards for making money as a swim pro are too low if MA gets a free truck from Toyota for doing nothing inspiring or significant.
The money is going to be drying up if that dude doesn’t get some results soon
Can someone plz tell the production crew not to switch camera angles in the middle of the start?
So is the US Open now considered to be a taper meet? Male sprinters almost never go fast without rest heading into the meet.
Almost everyone swims pretty fast when suited up. Who knows how much of that is psychological but my guess is the fast suits coupled with a big meet environment elicit fast swimming.
But we almost never see fast times like this in the men’s sprint events at the pro swim series, and they’re definitely not racing there in practice suits.
Probably helps that this is the first season without worlds/olympics in 5 years
Training is different than it was 20 years ago. Sprinters very often aren’t doing the same volume/fatigue throughout the season, so they don’t have the same drops.
Look at Cam McEvoy’s training—nothing is longer than 20m at a time.
It’s not that for Alexy at least.

200 fly all of a sudden seems like one of the deepest events on the us mens side.
urlando foster heilman jett laur julian all under 155 and a couple guys who can probably get under 155 in dahlgren schott shackell lucas (who looks like hes popping this season)
Depends on how far under 1:55. 1:54 is pretty meaningless at a big meet
154 was 3rd at worlds this year
is regan doing the double at finals???
She rarely shies away from doubles
This WR has to go down tonight
Which WR?
