Wieber, who led the Americans to the team title Tuesday, won despite making mistakes on uneven bars and floor exercise. She finished with 59.382 points, just 0.033 ahead of Komova. China's Yao Jinnan won the bronze, and Aly Raisman of the United States was fourth. Wieber had a big form break on uneven bars, leaving her trailing Komova by more than a point midway through the meet. Wieber pared the lead in half with a spectacular balance beam routine to go into the final rotation a half-point behind Komova, the Youth Olympic Games champion. The 16-year-old seemed resigned to silver after going out of bounds on her third tumbling pass. But while Komova's routine was clean, it was less difficult and didn't have the same spark as Wieber's, who became the sixth American to win gymnastics' biggest prize at worlds. Most had expected the gold duel to come down to Komova and Wieber with defending champion Aliya Mustafina missing to a knee injury. The American performed first and she seemed to lose rhythm as she pirouetted on the high bar. It caught up with her when she flipped to the low bar and although she didn't fall, she swayed and looked as if she might have scraped her toes on the mat. She scored a 13.6, more than a point less than she had in qualifying. Wieber's passes were higher and her form was just a little better and that, in the end, made the difference between silver and gold.
