Jordyn Weiber wins gold at gymnastic world championships

(CBS/AP) - With the London Olympics only nine months away, it's time to start getting pumped. Jordyn Weiber is pumped, with good reason. The 16-year-old American gymnast won gold at the world championships in Tokyo.

Weiber stunned Russia's Viktoria Komova to win the all-around title at the world gymnastics championships on Thursday night, rallying after making mistakes on both uneven bars and floor exercise. Wieber is the sixth American to win gymnastics' biggest prize at worlds, and adds a second gold to the one she won with her U.S. teammates on Tuesday night.

"I definitely thought I was going to end up with silver," said Wieber, who burst into tears when she saw the final score. "I'm so surprised."

Komova, too.

The Russian was the only one of the top five who didn't have a major mistake, and it still wasn't enough to win the gold medal. She doesn't have Wieber's difficulty after the ankle injury that cost her the first half of the year, and she doesn't have anywhere close to the Americans' presence.

Taken together, it was the difference between silver and gold.

The 16-year-old from DeWitt, Mich., finished with 59.382 points, just 0.033 ahead of Komova. The 16-year-old's mouth dropped open in shock, and coach John Geddert threw his hands in the air before sprinting down the floor.

China's Yao Jinnan won the bronze medal. Aly Raisman of the United States was fourth.

Weiber and Geddert both know that the best is yet to come. With the London 2012 Summer Games starting in July, the gymnastic competition looks to be fierce.

"We can get better," Geddert promised. "That will definitely be the drive. We're not going to sit back and go, 'Oh, we're the world champion, it's an automatic for next year, too.' It won't be that easy."
