China's Ye Shiwen set a world record to win gold in the women's 400-meter individual medley Saturday night, beating world champion Elizabeth Beisel of the U.S.
Australia's Stephanie Rice, the 2008 gold medalist, ended way back in sixth.
Ye's swim of 4 minutes, 28.43 seconds bested Rice's world record from Beijing by more than a second.
Beisel finished 2.84 seconds back for her first Olympic medal and said she was "totally satisfied" despite being the favorite.
"A gold would be a little bit cooler," she said, "but I can't complain. I'm just really excited."
China's Li Xuanxu took bronze.
