Simone Manuel pulled off another upset for gold.
Manuel won the world 100m freestyle title by upsetting world-record holder Sarah Sjöström in an American record 42.27 seconds in Budapest on Friday.
Sjöström took silver in 52.31, followed by Denmark’s Pernilla Blume in 52.69. American Mallory Comerford was fourth.
One year ago, Manuel and Canadian Penny Oleksiak were surprise Olympic 100m free co-champions, topping then-world-record holder Cate Campbell of Australia.
Manuel became the first U.S. woman to win the world 100m free title since Jenny Thompson in 1998.
