TOKYO, Japan -

TOKYO, Japan - Stanford sophomore forward Chioma Ubogagu and the United States captured the FIFA Under-20 Women's World Cup on Saturday in Japan with a surprising 1-0 victory over Germany.

Ubogagu came off the bench and played the final 30 minutes for the U.S., which reversed a 3-0 loss to Germany in group play

Ubogagu played in all six matches for the U.S., scoring in overtime to give the U.S. a quarterfinal victory over North Korea.

In the final, Kealie Ohai scored the winner in the 44th minute in front of 31,114 at Tokyo National Stadium. It was the third world women's U-20 title for the U.S, which previously won in 2002 (when it was a U-19 tournament) and in 2008.

"We believed we would win," Ohai said, on ussoccer.com. "Going into the game, we didn't care if they beat us 3-0 or they were better than us, today they're not going to beat us. We truly believed that going in and that's one of the reasons we ended up winning the whole thing."

The U.S. was coached by Steve Swanson, who went 49-28-4 as head women's coach at Stanford from 1996-99, advancing to the NCAA tournament three times, including a third-round appearance in 1999.

"The thing you have to understand about American teams and American players is there's nothing better for our players than to come up with a challenge," Swanson said.

After Sunday's Stanford match against Georgetown, Ubogagu will have missed the Cardinal's first six contests, but is expected to play on Friday when Stanford plays San Diego State at the Santa Clara Classic.
