USA Swimming dazzled with another set of standout performances on night five of the 2025 World Aquatics Championships, winning six medals and setting a new American record in the women’s 4x200-meter freestyle relay.

Regan Smith (Lakeville, Minn./Longhorn Aquatics) opened the night with a silver medal finish in the women’s 200m butterfly. Her time of 2:04.99 secured her third individual medal of the meet. Shaine Casas (McAllen, Texas/Longhorn Aquatics) followed suit by securing silver in the men’s 200m individual medley (1:54.30) after a hard-fought final 50. Casas’ new personal best time joins Ryan Lochte and Michael Phelps as the only men in American history to go 1:54.

Jack Alexy (Mendham, N.J./California Aquatics) powered to silver in the men’s 100m freestyle (46.92) before Katherine Berkoff (Missoula, Mont./Wolfpack Elite) struck gold in the women’s 50m backstroke. Berkoff’s time of 27.08 was her second-best time ever. Smith claimed her second silver medal of the evening with a time of 27.25, giving USA Swimming a 1-2 finish in the event.

The night closed with Claire Weinstein (White Plains, N.Y./Sandpipers of Nevada), Anna Peplowski (Germantown Hills, Ill./Indiana Swim Club), Erin Gemmell (Potomac, Md./Longhorn Aquatics) and Katie Ledecky (Bethesda, Md./Gator Swim Club) teaming up for silver in the women’s 4x200-meter freestyle relay, breaking the American record with a time of 7:40.01 to cap a six-medal session for USA Swimming in Singapore.

Casas on the race: “Everybody saw what happened last night, so that was definitely kind of on my mind. You know how talented and great Leon is, but I just kept telling myself that I'm a great competitor and I'm at the same level. We keep working and pushing towards getting to that mark as well. But I was pretty happy with that race. I feel like that's got to be one of the most competitive races in a long time, so I thought that was great to be a part of.

“I'm grateful for this new change that I have being with Bob (Bowman). Those guys are my teammates. So, there was not really this feeling of envy or any frustration, or any ill feelings toward each other. I was hoping they would swim well, and I'm sure they were hoping I would swim well. You could change out in any order, any of us Texas guys, and I'd probably be okay with that. At the end of the day, I did everything I could leading up to this meet. I'm pretty content with where I'm at.”

Casas on the rest of the meet: “(The next race) is the 100m butterfly tomorrow morning. Honestly, just keep moving forward and building off of this. I feel like I am starting to get back into the rhythm of being an elite athlete and a high-level performer. That’s my first step. Just keep getting better.”

Casas on showing what he’s capable of: “I've always known that I can do it. And now the swims are showing who I am, and I'm sure they'll be like, Oh, you can show up, you can ball out.”

Alexy on the race: “It was pretty good. I mean, I can't really complain. That was my second-best time of all time. (Swam) 46.81 last night. 46.92 again tonight under some pressure. Really happy with the swim, happy with my finish there. Obviously, would have loved to win, but it was really fun racing some of the fastest guys in the world.”

Alexy on his pre-race plan: “The plan is to walk in there and appreciate the moment. I've dreamt of competing at these world championship meets and representing Team USA since I was a kid. I was talking to David in the ready room, and we were wishing each other good luck, but also (talking about) putting on a good show for the fans and having lots of fun. 

Alexy on being on the podium: “After missing the podium last year at the Paris Olympics, in the individual event, it definitely feels great to be back on the podium. And it's great because it gives me something else to work towards, to get the gold medal in the individual race. I am really grateful for where I'm at right now and always hungry for more.”

It's definitely a huge accomplishment, been a dream of mine for a while, and I'm super excited to finally accomplish one of those dreams, so it feels really good. I was surprised when I saw my time. Especially after how last night felt, I was not feeling super optimistic. So I was super relieved and excited. It's a good moment.”

Berkoff on sharing the podium with Regan Smith: “She's awesome to have in the ready room. We always had a lot of fun together, so it's great to share the podium with her.”

Smith on a tight turn-around double: “Doubles are never easy, but I'm grateful that it was just a 50m backstroke, not 100m or 200m. The ready room for the 50m is really fun. There are a lot of great girls in there, and I love swimming with Katharine, so they gave me the energy to do what I needed to do. And I'm just excited to hear the anthem tonight.”

Smith on the USA one-two: “Really special and a long time coming, I think, and Katharine is such a beast in this event. And I know that this is her first-ever world title, and that's huge for her. So I'm just excited to share that moment with her.”

Gemmell on the team mentality for relays: “It’s always a lot easier to step up on a relay when you have your teammates behind you and that’s a great source of motivation. Keeping a positive mindset, my team is behind me, all my training has led to this.”
