Four of the Terrapin athletes in London are still in competition after Tuesday. For Terp Nation, the day was highlighted by a huge upset win in field hockey of No. 10 USA beating No. 2 Argentina, 1-0, in group play.

The U.S. beat Argentina, one of the world's top teams, for the third time in a year. USA's Shannon Taylor deflected in a pass from Michelle Vittese for the game's only goal with seven minutes left in the first half. HIGHLIGHTS | FULL REPLAY | PHOTOS
