Canadian swimming phenom Summer McIntosh was unable to beat American star Katie Ledecky in the women's 800-metre freestyle at the world championships Saturday, ending her quest to win five individual gold medals in Singapore.

Australian Kaylee McKeown and American Regan Smith went one-two in the 200m backstroke, just as they did in all three backstrokes at the 2023 Worlds, both backstrokes at the 2024 Olympics and in the 100m back earlier at these worlds.

In other events, Gretchen Walsh became the first American woman to win gold at the world championships in the 50m butterfly. Regan Smith and Claire Curzan took silver and bronze, respectively, in the women's 200m backstroke. Alexy's bronze in the men's 50 freestyle was his third medal of the 2025 world championships.
