Former Maryland star Katie O'Donnell helped Team USA defeat world No. 1 Argentina, 4-2, on Friday in the Pan American gold-medal game in Guadalajara, Mexico.
The win for the 13th-ranked U.S. team clinched a spot in the London Olympic Games next summer. Argentina, which won last year's world title, was undefeated in Pan Am play since 1987, when the sport was first included.
