Day 3 Finals Heat Sheets
Good evening all and welcome to the third night of finals at the 2025 U.S. National Championship! The first two days have seen some incredible swims, and we’re expecting more fireworks from Indianapolis, Ind., tonight. This evening, there are finals of the 400 IM, 100 butterfly, 50 breaststroke, and 50 backstroke.
The 100 butterfly races project to be the highlight of the session. Gretchen Walsh has been strong in Indianapolis and lowered her 50 butterfly American record last night, taking a couple more steps toward Sarah Sjostrom‘s legendary record. This morning in the 100 butterfly–where she already owns the world record–Walsh set herself up for success this evening with a 55.29. She’s over two seconds ahead of the rest of the field, which is led by Olympic gold medalist Torri Huske (57.80).
The men’s 100 butterfly prelims saw teenager Thomas Heilman take control. The Paris Olympian lowered the 17-18 National Age Group record this morning with a 50.78. He’s still looking for a spot on the World Championship team but has positioned himself well against a strong field that contains Dare Rose (51.15), Shaine Casas (51.46), and Luca Urlando (51.51).
Two-time Olympic medalists Emma Weyant and Katie Grimes aim to qualify for the women’s 400 IM tonight. Leah Hayes is the top seed coming into finals and is looking to return to the World Championship roster. On the men’s side, Carson Foster and Bobby Finke are the top two qualifiers for the championship final. Finke said last month that he won’t swim this event at Worlds if he qualifies (because of the conflict with the 1500 freestyle) adding another wrinkle into a final that looks quite different than it has in the past.
There’s always potential for drama in a 50 and that’s compounded by wide open races on the men’s side. Veteran Michael Andrew and teenager Campbell McKean are tied for top seed in the men’s 50 breaststroke, while Quintin McCarty isn’t far behind Casas, who has yet to be at his best in Indianapolis and has a double tonight. Lilly King leads the women’s 50 breaststroke field while behind her there’s a mix of Virginia Olympians and swimmers aiming for their first senior international teams. U.S. Open record holder Katharine Berkoff wasn’t far from that standard with a 27.15 this morning. But, breaking back onto the U.S. senior international roster last night in the 200 backstroke could be the start of a snowball effect for Claire Curzan.
