A look back at key moments in Monday's Canada-U.S. women's semi-final soccer match:
21 minutes: Christine Sinclair opens scoring, giving Canada a 1-0 lead against a rival it has not defeated since 2001. Marie-Eve Nault sent the ball to Melissa Tancredi, who slid it across to Sinclair who darted around her first marker, then went around American goalkeeper Hope Solo to score.
At the end of the first half, Canada led 1-0.
54 minutes: The U.S.team scored from a corner, as Megan Rapinoe slipped past the Canadian defence, tying up the game 1-1.
67 minutes: Sinclair again scored for Canada, taking a pass from Tancredi and firing it smartly off the post to bring Canada to a 2-1 lead. But this lead lasted only three minutes.
70 minutes: Megan Rapinoe of the United States scored from the side of the net, kicking it in off a goal post to even the score up again, now 2-2.
73 minutes: Sinclair made it 3-2 for Canada, beating two markers for the ball, and then scoring with a header past Solo.
80 minutes: Norwegian referee Christiana Pedersen penalized Canadian goalkeeper Erin McLeod for delaying the play – holding onto the ball more than six seconds. Pedersen tells McLeod she held onto the ball for 10 seconds. McLeod said later that wasn't even close.
The United States got a free penalty kick from outside the Canadian box.
Their kick struck Canadian player Nault on an arm, and Pedersen again ruled, assessing a handball against the Canadian. Nault had held her arms crossed in front of her body in a defensive posture. Nault made no move with her hands beyond pulling them into her chest.
Pedersen awarded the United States an indirect free kick just inside the Canadian area. Abby Wambach scored to tie the game 3-3 in regulation play.
124 minutes (final minute of added time): Alex Morgan of the United States scored with a header for a 4-3 United States win.
