TOKYO (AP) - Nigeria beat Mexico 1-0 on Desire Oparanozie's extra time goal to advance to the semifinals of the women's under-20 World Cup on Thursday.
Nigeria dominated the first hour but was unable to breakthrough until Oparanozie's header from Ugo Njoku's cross in the 109th minute at Tokyo's National Stadium.
Nigeria, runner-up at the 2010 tournament, will next play the winner of Friday's quarterfinal between the United States and North Korea on Tuesday.
Mexico had a chance to take the lead, but Yamile Franco hit the crossbar with an angled free kick in the first period of extra time.
Host Japan faces South Korea in the other last-eight match later Thursday. Defending champion Germany takes on Norway in Friday's quarterfinals.
