[UNDER-20 WOMEN'S WORLD CUP] Sydney Leroux came off the bench to score two goals and set up a third and lead the USA to a 3-0 win over France in its opening game at the Under-20 Women's World Cup in Chillan, Chile.

Leroux set up Cal sophomore Alex Morgan's game-winning goal in the 55th minute, then put the match away with goals in the 56th and 71st minutes. The UCLA freshman previously represented Canada at the 2004 Under-19 World Cup.

Penn State goalkeeper Alyssa Naeher made two spectacular saves in the second half to earn the shutout.

"It was a much closer game than the score indicated and I think Alyssa preserved the shutout with two fantastic saves," said U.S. head coach Tony DiCicco. "Today, it was Sydney who was the star. I have a lot of players who can step in and be the star. We felt that this was the right situation where Sydney could step in and help us in the second half. She was very determined to prove that we were correct."

Argentina and China played to a 0-0 tie in the first game of the doubleheader.

The Americans will take on Argentina for their second match in Chillan on Saturday (live on ESPN360.com at 10 a.m. ET) before traveling to Temuco to face China on Tuesday (TV: ESPNU, live, 2 p.m. ET).
