Day 4 Prelims Heat Sheet
The fourth and final day of the 2025 US Summer Championships sees some familiar names upon the scratch list as Claire Weinstein has dropped both the 200 free and 800 free. Weinstein, who won the bronze medal in the 200 at the 2025 Singapore Worlds, has not competed in an individual event this week, only swimming the opening leg of the Women’s 4×100 free relay for her team, the Sandpipers of Nevada. Her fellow Singapore Worlds and Sandpipers teammate, Bella Sims, will take over the top seed in the 200 free, while Australia’s Tiana Kritzinger will move into lane 4 in the 800 free.
Fellow top eight seed, Jack Dahlgren has dropped out the 200 free as well. Dahlgren was seeded 5th at 1:46.58, but likely is sitting out the first event of the day to focus on the 200 fly, where he and the top seed, Trenton Julian will be chasing the 1:53.70 that currently sits in 2nd place on the Pan-Pacs roster in the event. Dahlgren was one of five swimmers seeded under 1:47, with the group being led by Kieran Smith at 1:45.39. Smith, provisionally made the Singapore roster, but due to roster constraints did not make the trip to Worlds.
The women’s and men’s 100 breast events, either saw no scratches, as is the case of the women’s race, or just two, on the men’s side, with Joe Polyak the 7th seed, the highest to withdraw.
Both 200 fly event saw enough scratches to condense to just prelims heats. The aforementioned Trenton Julian leads the men’s field while Alex Shackell, a 2024 Olympian in this event leads the women’s field and will look to not only hold off Bella Grant and Rachel Klinker but also fight for a spot on the Pan-Pacs roster in this event.
There have been a few additions to the heat sheets this morning as Joshua Chen has jumped into the 100 breast as the 8th fastest seed and David Johnston, who scratched the 800 free on night one has added the 1500 free to his program. With a reshuffling of the Pan-Pacs roster, by the addition of Van Mathias and potentially others, Johnston will be looking to improve his time in this event in order to better his standing among priority two swimmers and remain on the team.

To be fair this was a known known: Johnston was written in at the bottom of the positive check in page at the clerk of course very early in the meet.
Having said that, a strict constructionist meet letter reader like myself would argue that under the circumstances where we are going to alllow potential team selection swimmers to get favorable treatment by the meet ref, then Hunter Armstrong should have been granted a stay of execution on his no show and been allowed to swim his other events yesterday.
The inconsistency is worse than the action itself. Come on refs. Pick a spot.
I support him being able to swim the event, but since when is it allowed to just add events to your schedule mid-meet lol
For all the commenters upset about the selection process and “so-and-so should get another chance,” they all had this option. Johnston probably didn’t want to swim another 1500 after flying back from Singapore, but he’s gotta go for broke now that his spot has been (likely) taken by Mathias. Gutsy!
