We have made it to the final session of the 2026 Westmont Pro Swim Series, and there are some exciting events in store for tonight’s finals session.

The meet will start with the 100 fly finals, where Gretchen Walsh and Dare Rose are the respective top seeds. Walsh has the potential to take over the entire top 10 list tonight, pushing former World Record holder Sarah Sjostrom out of the list entirely.

Summer McIntosh and Finlay Knox will follow as the top seeds in the 200 IM. McIntosh was just off her personal best in the 200 freestyle last night, and will be looking for a new PSS and U.S. Open record in the event tonight.

The 50 breaststroke finals will follow the 200 IM, and Skyler Smith and Michael Andrew are leading the field, both sitting a few tenths ahead of the rest of the final.

In the 100 backstroke, Isabelle Stadden, who has been having an exceptional meet, is the top seed of 58.26, coming in about a second ahead of Katharine Berkoff. Ivan Tarasov is the top seed in the men’s backstroke, just ahead of Blake Tierney and Shaine Casas.

Katie Ledecky and Lucas Henveaux are the respective top seeds in the 400 freestyle, and while Ledecky is the clear favorite to win, Henveaux has some tight competition from Sam Short, who has set two PSS records in two distance events.

The meet will wrap up with the 50 freestyles where Gretchen Walsh will swim her 2nd event as the top seed, ahead of Rylee Erisman and Olivia Smoliga. Nikita Sheremet is the top seed on the men’s side, and he will be trying to hold off Chris Guiliano, who has already won the 100 and 200 freestyle this week.
