After picking up a bronze on the balance beam, Aly Raisman just drilled her floor exercise.
With a series of intricate tumbling combinations, Raisman wowed the crowd, the judges and even herself. She struck her finishing pose as the music ended, then could be seen saying, "Wow" to herself.
Hard to argue. She got a 15.600, which was good for first place after four competitors.
Romanian Catalina Ponor, demoted to fourth on the beam after the Americans won an appeal on Raisman's score, had the compensation of floor silver while Russia's Aliya Mustafina took bronze.
American Jordyn Wieber, who missed the chance to qualify for the all-around final here despite being world champion, went home with no individual medals, finishing seventh on the floor after stepping out of bounds twice.
The only woman behind her was Izbasa who crashed to her knees as she tried to land her final tumbling pass and incurred a penalty of 0.3 points.
