Wednesday Finals Heat Sheet

Welcome to the 2nd finals session of the 2025 U.S. Summer Championships. Yesterday we saw some exciting swims and some new personal best times, and there are six events this evening where we could see some exciting swims, and potentially some shake-ups to the Pan-Pacs roster.

As a reminder here is where the roster sits currently.

Tonight, we will see the finals of the men’s and women’s 400 freestyle, 100 butterfly, and 200 breaststroke individually. The meet will also end with the 400 freestyle relay.

The women’s 400 freestyle is led by 17-year-old Madi Mintenko as the only swimmer under 4:10 this morning. The men’s 500 freestyle will see Matthew Galea, an Australian swimmer, and Aaron Shackell separated by less than a tenth-of-a-second.

Alex Shackell, a 2024 Olympian, is the top seed in the women’s 100 butterfly at 57.69, more than a second ahead of the rest of the field. The men’s event is slightly closer but top seed Trenton Julian still comes in about half-a-second ahead of the 2nd seed.

The final event, the 200 breaststroke will see two ends of the swimming spectrum in the women’s ‘A’ final. Gabby Rose, a 47-year-old, is the 2nd seed and she will swim in lane five, while 16-year-old Sofia Szymanowski, one of the youngest swimmers at the meet will swim in lane eight. Australia’s Sienna Harben is the top qualifier in 2:28.15, almost two seconds ahead of Rose.

The men’s final will feature Indiana’s Jassen Yep as the top seed, just two tenths ahead of teammate Charlie Egeland.

Walker began building from there, splitting 31.59/31.33 on the 3rd 100 to flip just one hundredth behind Sims who split 32.26/32.05. She took over the lead at the 350 mark, flipping in 31.22 to Sims’ 31.58, and Walker held on for the final 50 to touch in in 4:07.22, beating Sims, who touched in 4:07.34, by just over a tenth of a second. Walker was 30.24 on the final 50 to Sims’ 30.01.

Madi Mintenko, the top seed from prelims, touched in 4:08.62. This was a new season best time for her, improving from her 4:09.34 from the prelims. She was about a second off her lifetime best of 4;07.53 from last summer’s Olympic Trials.

Australia’s Matthew Galea touched in 3:48.15 to walk away with the bronze.

Alex Shackell followed up her brother’s event win with a win in the women’s 100 butterfly, coming in more than a second ahead of the rest of the field in 57.34 to take just over three tenths off her prelims swim of 57.69. This time was faster than the 57.71 she swam at the U.S. Trials in June, but it does not move her up the Pan Pacs rankings. She was also a little more than half-a-second ahead of her personal best 56.78 from the Olympic Trials.

Isabella Boyd and Bella Grant, both Australian swimmers, tied for the silver medal at 58.63. Grant was out first in 27.45, more than two tenths ahead of Boyd’s 27.69, but Boyd came back in 30.94 to Grant’s 31.18.

Ava Chavez won the ‘B’ final in 59.01, which would have been 5th in the event. This was a best time by almost half a second for the Cal Bear.

Top 8 Finishers

1. Ben Armbruster (AUS)- 50.91
2. Aiden Hayes (WOLF)- 51.24
3. Trenton Julian (MVN)- 51.38
4. Evan Fentress (OSU)- 52.12

6. August Vetsch (CAL)- 52.47
7. Jack Dahlgren (UN)- 52.52
8. Grant House (SUN)- 53.26

Australia’s Ben Armbruster swims 50.91, splitting 23.58/27.33 in the men’s 100 butterfly, cracking 51 seconds and setting the 2nd fastest time in Australia this year. He comes in just behind Matthew Temple, who has a season best time of 50.57 from the World’s final where he finished 5th overall. Armbruster was 3rd at the Australian Trials in 51.45 behind Temple and Jesse Coleman, who came in at 51.00 and 51.09 respectively.

Aiden Hayes from the Wolfpack Elite came in 2nd at 51.24 for the silver, exactly tying his best time in the event from July of 2023. He was out in 23.82 and came home in 27.42 to touch just over a tenth ahead of Trenton Julian.

Hayes is just getting back into racing after he took the whole 2024-2025 season off following a wrist fracture. In 2023, he won the NCAA title in the men’s 200 butterfly, and in 2024, he split the fastest 50 backstroke of all-time in 20.07.

He swam his first meet since the 2024 Olympic Trials in May, touching in 52.52 in the 100 fly. At US Nationals in June, he was a bit faster in 52.05 to finish 9th. He seems to be back in his pre-injury form now, and will be returning to the NC State team as a redshirt senior for the 2025-2026 season

Trenton Julian swam 51.38 for the bronze, getting out just behind Hayes in 24.34 but coming home the fastest in the heat at 27.04 to be the final swimmer under 52 seconds.

Gabby Rose finished 2nd in 2:30.83, a little more than a second faster than the 2:32.03 she swam to qualify for the final. She was out in 1:12.23 and came home in 1:18.60, out splitting Isabelle Odgers on the back end to win the silver.
