Abby Wambach's goal in the dying moments of the first half was enough to lift the U.S. women's national team to a 1-0 win over Nigeria, cementing a first-place finish in Group D.
Wambach, whose recent comments regarding playing on artificial turf have put her back in the spotlight, scored on a one-time volley off a Megan Rapinoe corner kick in the 45th minute. Wambach, whose goal was the 14th World Cup goal in her career (second-most all-time) was restored to the starting lineup, and she began the game next to Alex Morgan, who earned the first World Cup start of her career. Morgan made way for Vancouver-area native Sydney Leroux in the 65th minute.
The USA had a goal from center back Julie Johnston waved off early for an offside call, despite replays showing she was even with Wambach on a squared header.
Johnston then came up big for the USA defense, tracking back and making a potential goal-saving slide tackle by deflecting Asisat Oshoala's attempt from close range. With the shutout, Johnston, Hope Solo & Co. have not conceded a goal in 243 minutes.
Nigeria goalkeeper Precious Dede kept the deficit at one through with a series of saves on her end, none bigger than her stopping Morgan on the doorstep with a sliding stop just into the second half, after Ali Krieger had set Morgan up with a cross from the right.
Nigeria went down to 10 players in the 69th minute, when Sarah Nnodim was sent off for her second yellow card after sliding through Leroux on a tackle.
Late on, U.S. veterans Shannon Boxx and Christie Rampone made their first appearances of the tournament, with Rampone (39) becoming the oldest player to appear in a Women's World Cup match.
With the win, the USA secured first place in its group, avoiding a round-of-16 matchup with Brazil. Instead, the USA will play the third-place finisher from Group B, E or F and is in line to play either China or Cameroon in the quarterfinals, should it advance.
