The United States went ahead early when midfielder Lori Lindsey unleashed a 23-yard blast that blew by Canada's Kathryn Clewley. Jena Kluegel's corner kick from the right side sailed long and the ball skidded out to Lindsey who launched a left-footed bomb into the right side netting.
Canada's star striker Sarah Barradas entered the game with a tournament high 7 goals, but the United States defense never allowed her to enter the flow of the game. She took three shots in the game, none of them on goal.
"I think that we played well in the back," U.S. coach Jay Hoffman said. "The chances they got we were able to shut down quickly."
Canada's best opportunity came in the 51st minute after a Catherine Reddick foul gave the Canadiens a free kick from 30 yards out. Canada's Randee Hermus fired a shot from the re- start and was able to get it past U.S. goalkeeper Hope Solo, but the crossbar proved to be on the American side today and denied Hermus' well-taken kick.
Marcia Wallis and Kim Patrick combined to free Catherine Reddick for Reddick's second goal of the tournament in the 44th minute. Wallis took a Patrick pass and took a shot from eight yards out that Clewley saved, but Wallis controlled the rebound and touched the ball to Reddick. The U.S. defender was able to finish from six yards out.
Patrick added her name to the scoresheet in the 53rd minute with another spectacular goal. In the team's opener, Patrick scored with a 30-yard rocket, and tonight she topped that with a 35 yard bomb into the upper right corner.
The win means that the United States will face Costa Rica on August 2 at 10:00 a.m. when the women's tournament moves to the Winnipeg Soccer Complex. In the other semifinal, Canada will face Mexico at 2:30 p.m on Monday.
The U.S. topped Costa Rica 6-0 in the team's first match on July 23, when the United States' scored three times in the first seven minutes. Lauren Molinaro scored twice in the win.
