After Certeza scored the game-tying goal Taylor Donohue grabbed the draw control and George Washington had the ball for 1:34, but could not get a shot off in that span to send the game to a second overtime.

Lucy Pompa (Baltimore, Md./Bryn Mawr) got the draw control to open the second overtime session. The Mount held onto the ball until a foul in the box was called with six second left and Johnson buried the shot to give the Mountaineers the come-from-behind victory.

The game did not look like it was destined to come down to the wire from the start of the day. The Colonials had control of the game until the Mountaineers 6-0 run to end regulation.
