TOKYO - Jordyn Wieber of the United States won the women's all-around gold medal in the gymnastics world championships Thursday, outscoring Victoria Komova of Russia and Yao Jinnan of China.    

The 16-year-old US Champion Wieber came from behind to notch a highest 15.266 points on the beam, and outperformed 2010 Youth Olympics champion Komova on the floor, the last rotation, to collect a total of 59.382.

Komova lost by a marginal 0.033 to finish at 59.349, and Yao ranked third with 58.589 points.

"I wasn't expecting to see my name on the top," said Wieber, " but when I saw it I was just so overwhelmed and excited and it was great."

Wieber staged a clean start, earning 15.716 points on the vault, highest of all gymnasts. But the next rotation saw her hands slipped from the uneven bars and she scored only 13.600 compared with Komova's 15.400.

"I had a little mistake on the bars and I knew that is going to affect me a little bit, but beam and floor are the two more events and I have to remember," Wieber said. "I used the prelims and team final as a little of confidence to compete in the last two event."

The United States also claimed the women's team title, making it by far the top-ranking nation on the medal tally.

China's Yao, a rising star and a strong participant in the 2011 world cup series, performed most of her routines in a stable fashion. The only major error was that she fell from the beam.

"I was a bit nervous on the beam, because my teammate fell down, " she said. "I will continue to train hard for higher difficulty."

All the three all-around medalists are in the first year of the senior competition, while defending champion Aliya Mustafina of Russia is missing this year's championship due to a knee surgery.

"I felt that there is a lot of very great gymnasts coming out and this is their first year in senior, and it's exciting to have a new generation of girls competing, and myself included," the new world champion said.
