USA Swimming athletes opened the 2025 World Aquatics Championships with gritty performances on night one in Singapore.  With several athletes battling illness, the Americans leaned on both youth and veteran leadership to secure podium finishes in individual and relay events.

In the first semifinal of the evening, Gretchen Walsh (Nashville, Tenn./New York Athletic Club) earned the top qualifying spot for tomorrow’s final in the women’s 100-meter Butterfly with a time of 56.07.   Later in the session, Josh Matheny (Pittsburgh, Pa./Indiana Swim Club) and Alex Walsh (Nashville, Tenn./New York Athletic Club) grabbed critical qualifying spots in the finals of the men’s 100m Breaststroke and Women’s 200m Individual Medley, respectively. 

In the women’s 400m freestyle Katie Ledecky (Bethesda, Md./Gator Swim Club) battled down the stretch to finish on the podium with a final time of 3:58.49. Twelve years after winning in the same event in Barcelona, the bronze was Ledecky’s twenty-seventh world championship medal and gave her momentum as she prepares for her signature events later in the competition. The American 4x100m Freestyle relay teams added two podiums to finish the session, setting the tone for a week of determined racing in Singapore.

Women’s 400m Freestyle- FINAL

3 – Katie Ledecky (Bethesda, Md./Gator Swim Club), 3:58.49

Ledecky on the result: “I would’ve liked to be a little faster. I was a little faster earlier this year, so there’s always that slight bit of wanting to be better than that. But I can’t complain with the medal. Fourth place was a 3:58 so that could have easily been me.”

Ledecky on her next few races: “I think the first day is sometimes a hit or miss for me at these Worlds. I’m really excited for the distance races, I mean that’s kind of my thing. The 400 is too I guess, but I’m really excited for the 1500 tomorrow.”

Kate Douglass (Pelham, N.Y./New York Athletic Club)

Erin Gemmell (Potomac, Md./Longhorn Aquatics)

Torri Huske (Arlington, Va./Arlington Aquatic Club)

Manuel on winning silver: “It means a lot. I think the team has definitely had to be adaptable and resilient, and for us to still post a solid time and put together really good splits is something that we can be really proud of, given the circumstances we have had to deal with.”

Gemmell on her late callup and reaction to the relay lineup change: “They told me I needed to be ready, and when someone tells you that you’re going to be on a finals relay for Team USA, I feel like you sort of lock in and you get in the zone. I’m really proud of what I was able to do with that.”

Men’s 4x100m Freestyle – FINAL

3 – USA, 3:09.64

Jack Alexy (Mendham, N.J./California Aquatics)

Patrick Sammon (El Dorado Hills, Calif./Sun Devil Swimming)

Chris Guiliano (Douglassville, Pa./Longhorn Aquatics)

Jonny Kulow (Lander, Wyo./Sun Devil Swimming)

Alexy on the result: “Not everything is going to go perfect, but we’ve been training really hard in the past month since (Toyota National Championships). I know these guys have worked really hard. Obviously, we’d like to get to the top of the podium, but can’t complain with bronze going into the next three years. I’m really proud of these guys and it’s not a bard start for Team USA.”

Sammon on his swim: “Jack got the lead for us – it was great to dive into some clean water. Overall, I thought it was a great experience. This was my first final and it couldn’t have been better than doing it with anyone else other than these guys.”
