WATCH: Team USA Stuns Canada

Alex Morgan scored a 123rd minute goal to lift the U.S. women's soccer team to a dramatic 4-3 extra time victory over Canada in the Olympic women's soccer semifinal.

Christine Sinclair opened the scoring in the 22nd minute, putting the U.S. on its collective heals.

Rapinoe scored in the 54th minute on a rare piece of corner kick brilliance. Rapinoe bent the corner kick directly into the net.

Sinclair had an answer for that with a 67th minute goal, but Rapinoe scored again on a wonder strike in the 70th minute. Sinclair had an answer again three minutes later, but Wambach would score from the penalty spot in the 80th minute.
