The United States won the women's under-20 World Cup in Santiago, Chile on Sunday, beating defending champion North Korea 2-1 on first-half goals from Sydney Leroux and Alex Morgan.

Leroux, who was born in Vancouver and now plays for UCLA, found the net in the 23rd minute with a shot from inside the box that ricocheted in off the defence, and Morgan scored in the 42nd with a left-footed shot from 20 yards that went high into the goal.

Cha Hu Nam scored a consolation goal for North Korea in the 90th.

The American players celebrated their victory by holding a large white sign reading "Gracias Chile" (Thanks Chile) in red letters in front of 12,000 cheering fans.

Earlier, Marie Pollmann scored a first-half hat trick for Germany, who beat France 5-3 to finish third.

Pollmann found the net in the 10th, 29th and 31st minutes, while teammates Julia Simic in the 67th and Lisa Schwab in the 80th also scored.

Marine Pervier scored twice for France, her first coming just before halftime and her second in the 75th. Marie-Laure Delie added the team's third in injury time.

Leroux played for the Vancouver Whitecaps as a teen and for Canada's under-15 squad in 2005.
