MANCHESTER, England -- The United States clinched first place in its group in Olympic women's soccer Tuesday with a 1-0 win over North Korea.
Abby Wambach scored in the 25th minute for her 141st international goal and third of the tournament. Wambach put home a pass from Cal product Alex Morgan.
Nearly 30,000 attended the first women's soccer game played in 23 years at Old Trafford, the home of Manchester United -- one of the most storied teams in the English Premier League.
The Americans won all three of their group games and were already assured a berth in the next round heading into Tuesday's game. They now move on Newcastle for a quarterfinal match on Friday.
The North Koreans, who finished 1-2 in pool play, are ranked in the top 10 in the world. But they remain an unknown in women's soccer because their players and officials have limited interaction with other teams. They completed the game with 10 players after Choe Mi Gyong was sent off with a second yellow card in the 81st minute following a tackle on Lauren Cheney.
North Korea had several scoring threats in a three-minute stretch midway through the second half, forcing Hope Solo to the ground twice to preserve the shutout.
Offensively, the Americans can be concerned about a second straight game in which on-the-field dominance failed to produce a comfortable margin. They held a 1-0 lead over Colombia until late in the second half Saturday before pulling away
The lone goal was set up by Cheney's long ball to Morgan, who slid a pass between two defenders to Wambach for an easy tap-in. The U.S. players celebrated by forming a line facing the crowd while holding hands -- then they starting wiggling their arms as if to create the look of a giant, slithering snake.
