The USA could have been eliminated if they failed to win against Costa Rica, but Dempsey’s 50th goal opened the floodgates, as they saw off their opponents with a 4-0 win.
Dempsey scored from the spot as early as the 9th minute after Bobby Wood was brought down in the box. Yedlin set up the play for Wood, who was ready to fire, before he was hacked down.
The attacker played as a striker in the first game, but slid into an attacking midfielder role on Tuesday, where he was more comfortable and assisted the second goal.

The Costa Rica defence fell apart after the second goal, with left back Fabian Johnson causing them problems and setting up the third goal, with Bobby Wood turning in time to fire in the third goal in the 42nd minute.
The second half was a little more subdued with the game already out of hand, and Costa Rica opting to sub out Joel Campbell, but Graham Zusi, who came on in the 70th minute, added a fourth goal in the 87th minute after stealing a pass.
