After a physical and hard fought match, Alex Morgan scored a goal against Canada in the 122 minute.
The goal sends the United States' women's soccer squad to the gold medal match against Japan on Thursday.
For the Canadians this is absolute heartbreak. The United States has quite simply dominated historically but this match, they held their own and had a chance to reverse a 26-match losing streak against the U.S.
But it all came to an end in the final seconds. Morgan headed a goal with less than 30 seconds to go.
In an interview with NBC after the game, Morgan called the game a "crazy battle."
On the goal, she said: "I got my head on it at the end and I didn't even see it go in."
