A revised version of the heat sheets for this weekend’s Pro Swim Series opener in Austin, Texas is absent a number of big names, with a handful of other significant scratches revealed by the Wednesday morning heat sheets.

Out of the Meet

The biggest names to have fully withdrawn from the meet include US National Team members Hunter Armstrong and Grant House.

The two-time Olympian and three-time Olympic relay medalist Armstrong has raced sparingly since the Paris Olympics, citing financial hardship behind the hiatus. That included skipping the World Championship Trials in 2025.

He did race at the U.S. Open in December, but only briefly: he finished 14th in the 50 free final (22.35) and 14th in the 50 back prelims (25.65) before scratching the B-Final.

In Austin this week, he was scheduled to race the 50 free (#8 seed), 100 back (#2 seed), 50 fly (#8 seed), 50 back (#2 seed), and 100 free (#6 seed).

Fellow U.S. National Team member Grant House has also pulled out of the meet. He had 5 entries in the meet including 5th in the 200 IM and 6th in the 100 fly.

House recently posted a video of a “speed practice” at Arizona State, so the reason behind his withdrawal is not obvious.

Other full-meet withdrawals include:

• 17-year-old Addison Bitel from Laker Swim in Florida, who was the #5 seed in the thin women’s 50 and 100 meter breaststroke fields, plus 6th in the 200 breast. Her teammate Brynn Lavigueur, the #6 seed in the 50 back and #7 seed in the 100 back, also scratched the meet.
• 16-year-old Natalie Bradac from the University of Denver Hilltoppers club team, the #9 seed in the 100 breast

Last-Minute Additions

In addition to the scratches, there were some last minute additions to the meet entries. That includes breaststrokers Luke Barr and Mitch Mason, who are both training with Coley Stickels‘ pro group at Texas Ford Aquatics.

They are the #7 and #8 seeds in the 100 breaststroke, with the versatile Barr also holding high seeds in the 50 fly (#9), 100 fly (#7), and 50 back (#6).

Wednesday Scratches

The most significant scratch from the final psych sheet to Wednesday’s heat sheet is French international Pauline Mahieu. Part of a large contingent of French swimmers at the meet, Mahieu was the #2 seed in the 100 back.

That is her only entry of the meet, so in essence she has scratched the meet.

While one recent Instagram post from last week said that she planned to leave for Los Angeles for a camp with the French team on January 5, her Instagram story on Tuesday shows her dragging a sled with groceries across the snow with the caption “change of scenery.”

The women’s 1500 free also saw scratches from the #2, #3, and #4 entries behind the event’s most dominant swimmer ever Katie Ledecky.

The #2 seed Claire Weinstein, the #3 seed Ashley Twichell, and the #4 seed Caroline Pennington are all absent from the heat sheets in a field that has been reduced to only its 8 swimmer ‘fastest heat.’

Weinstein, a freshman at Cal, is still entered in the 50 free as the #11 seed, while Twichell and Pennington won’t race on Wednesday at all.

Also dropping as a high seed is teen phenom Rylee Erisman from the women’s 200 IM. She was the 4th seed in that event, but it was one of two possible races on her schedule for the day. She will still race a very good field in the women’s 100 back, where she’s the 4th seed, but was never entered in the 50 free, which is one of her primary events.

The other big scratch from Wednesday’s heat sheets is Kato Trinquesse, another Denver Hilltopper drop from the women’s 100 breaststroke field. She was promoted to the #7 seed after her teammate withdrew from the meet.
