The United States, the defending champion, qualified for the knockout stage of the Women's World Cup after a goalless draw with Portugal in their first appearance at Eden Park in Auckland on Tuesday. The four-time world champions faced a crucial match but squandered several chances to score, and the return of veteran Megan Rapinoe in the second half did little to change things against Portugal's physically strong defense. The U.S. team avoided a dangerous opportunity in stoppage time when the post denied a shot from Ana Capita. Minutes later, Capita earned a free kick at the edge of the penalty area, but the U.S. held firm in the tough closing minutes. The United States qualified for the Round of 16 in Melbourne, where they will presumably meet Sweden after finishing second in Group E behind the Netherlands.
