Swim of the Week is brought to you by arena, a SwimSwam partner.
Disclaimer: Swim of the Week is not meant to be a conclusive selection of the best overall swim of the week, but rather one Featured Swim to be explored in deeper detail. The Swim of the Week is an opportunity to take a closer look at the context of one of the many fast swims this week, perhaps a swim that slipped through the cracks as others grabbed the headlines, or a race we didn’t get to examine as closely in the flood of weekly meets.
Lakeside Swim Team standout Wilson York has been making headlines over the last few years for his record-setting performances in the breaststroke events, but he’s started to become an elite all-around swimmer, and that was on display at last week’s Pro Swim Series in Austin.
York, who turned 16 in November, took on a busy schedule at the meet, contesting six different events, and the biggest highlight came in the 400 IM.
After clocking 4:26.45 in the prelims, advancing 2nd into the final behind Leon Marchand, York used a blistering breaststroke split in the final to snag 3rd place on the podium and set a new personal best of 4:22.20.
York finished in the bronze medal position behind a pair of Olympic champions, with Marchand winning in 4:13.21 and Bobby Finke taking the runner-up spot in 4:18.35.
York’s swim lowered his previous best of 4:24.72, set last May at the 2025 Pro Swim in Fort Lauderdale.

| 4:24.72 (30.66) | 4:22.20 (30.77) |
Despite York’s 1:12.02 breaststroke split in Austin—second only to Marchand’s 1:11.76 in the final—the largest gain relative to his previous best came on the backstroke leg. York split 1:09.19 in Austin after going 1:11.42 at Fort Lauderdale last May.
The performance vaulted York from 57th to 28th all-time among Americans in the boys’ 15–16 age group.
