HIROSHIMA, Japan (AP) -- Substitute Lina Magull scored an injury-time winner on Thursday as defending champion Germany beat Ghana 1-0 at the women's under-20 World Cup while North Korea coasted to a 9-0 thrashing of Argentina.
Magull, who came on in the 83rd minute, took a perfect pass from Dzsenifer Marozsan and beat Ghana goalkeeper Patricia Mantey with an angled left-footed shot in the first minute of injury time as Germany improved to six points in Group D.
"It was very exciting to get a goal so late in the match like that," Germany coach Maren Meinert said. "The players worked very hard and were rewarded for their work. Ghana was a tough opponent and we had to think about different formations."
The United States was held to a 1-1 draw by China in Group D's second game of the day, a result that ensured Germany became the first team to advance to the quarterfinals.
Shen Lili scored with a superbly struck drive from the top of the area in the 19th minute and Maya Hayes equalized for the Americans with her fourth goal of the tournament in the 36th. The U.S. has four points and must avoid defeat in its final group match against Germany to definitely advance.
"I thought we played well in stretches," U.S. coach Steve Swanson said. "It's too bad we gave up that early goal which was China's only real chance. This was not the result we wanted but I thought we played well, now we have to just turn our thoughts to the next game."
China, which has one point and still has a chance of advancing, plays Ghana in its last game of the group stage.
In Group C, Kim Un Hwa scored five goals to lead North Korea to a rout of Argentina, which gave up six goals in its first game against Canada. Kim Su Gyong had a hat trick and Yun Hyon Hi scored the other goal for the 2006 champions who have six points.
Also in Group C, Ada Hergerberg scored just after the break and her sister Andrine scored the winner 11 minutes from time as Norway beat Canada 2-1, a result that left both teams with three points.
