But here’s where it gets controversial: several big-name favorites faced stiff competition, and some veterans struggled with the double-event pressure, sparking discussion about depth vs. specialization in elite sprint and distance events. This article rewrites the original schedule and results in a way that highlights strategic choices swimmers made under the meet’s unique format, while keeping all key information intact.

Detailed meet materials were available through Meet Central, the official psych sheets, and live results portals.
Finals session: Day 4 focus and order

Key highlights from the meet to this point
Across the first three days, numerous meet and pool records fell, including a preliminary meet and pool record set by Jack Alexy with a 47.66 in the 100 freestyle to secure the top seed for finals. In the women’s 100 freestyle, Simone Manuel led Kate Douglass and Gretchen Walsh after a remarkable 200 freestyle the day before secured the event win. Summer McIntosh challenged the field in the women’s 200 butterfly, aiming to surpass Regan Smith’s U.S. Open and meet marks and push toward a World Record in the event.
Contenders and strategic notes
- Regan Smith entered the 200 butterfly with high expectations despite a demanding double in the 200 back and 200 fly, which could influence her performance in both races. She was seeded second in both events, with Phoebe Bacon ahead of her in the 200 back.
- The men’s 200 butterfly presented a tight race between Hubert Kos and Ilya Kharun, with Kos holding the top seed by more than a half-second. Both swimmers were also targeting the 200 backstroke double. Kharun’s schedule included another 50 fly exposure.
- Leon Marchand added the 200 butterfly to his program, seeded fourth behind Kos, Kharun, and Cooper Lucas from Texas, highlighting the depth of events and the potential impact of double-program athletes.
- In the distance events, Mila Nikanorov led the women’s 800, while Bobby Finke led the men’s 800, though Finke’s form at this meet left room for overtakes by seeders like Aiden Hammer and Ilia Sibirtsev.
- Gretchen Walsh continued to demonstrate sprint versatility, top-seeded in the women’s 50 butterfly with a prelim time of 25.43, placing her more than a second ahead of the field.
- Kate Douglass and Noah Cakir carried top seeds in the women’s and men’s 200 breaststroke, respectively, each leading by roughly half a second over their solid challengers Mona McSharry and AJ Pouch.
