Key Events of Day 4 Finals
The final session began with the men’s and women’s 800 freestyle events, a demanding test of endurance and pacing. The program then progressed through the 50 butterfly, 200 backstroke, 200 breaststroke, 100 freestyle, and concluded with the 200 butterfly, providing a full spectrum of sprint to distance racing in a single evening.
Record-Breaking and Standout Performances
Among the notable highlights, Jack Alexy set a blazing 100 free time of 47.66 seconds in prelims, earning the top seed going into the finals and signaling a potential breakout performance at this level. In the women’s 100 freestyle, Simone Manuel led a star-studded field that included Kate Douglass and Gretchen Walsh, following Manuel’s impressive 200 free win the day prior.
Eyes on Regan Smith and World Records
Summer McIntosh was set to challenge Regan Smith’s U.S. Open and meet records in the women’s 200 fly, with the added ambition of approaching a World Record in the event. Smith herself faced a grueling 200 back/200 fly double that could influence her outcomes in both events. Phoebe Bacon stood close behind in the 200 backstroke seedings.
Double-Duty Finals and Strategic Entries
Several men and women entered doubles, aiming to optimize rest and peak performance across two events. Hubert Kos and Ilya Kharun led the men in the 200 fly, with Kos carrying the top seed by more than half a second and both athletes navigating other events in their double-program campaigns. Leon Marchand was another notable competitor in the 200 fly, seeded fourth behind Kos, Kharun, and Cooper Lucas of Texas.
Swimercrowd favorites and seed dynamics
Mila Nikanorov led the women’s 800 free as the top seed, while Bobby Finke led the men’s field, though he faced a tough meet where his form could slip behind Aiden Hammer or Ilia Sibirtsev as the rounds progressed.
In analysis of sprint events, Gretchen Walsh entered the 50 fly as the top seed with a prelim time of 25.43, giving her over a second margin over the rest of the field. Kate Douglass and Noah Cakir held the top seeds in the 200 breaststroke events for women and men, respectively, while Mona McSharry and AJ Pouch trailed closely behind.
