Katie Johnson broke a tie in the 75th minute and Southern California won the NCAA women's soccer title Sunday, beating top-ranked West Virginia 3-1 at Avaya Stadium on Sunday.
The second-seeded Trojans (19-4-2) also won the College Cup in 2007.
The Mountaineers (23-2-2) lost for the first time since a 1-0 setback to Georgetown on Sept. 18. West Virginia had a 17-game unbeaten streak snapped, and allowed three goals for the first all season.
Johnson, who also had the winning goal in USC's 1-0 semifinal victory over Georgetown on Friday, was wide open in front of the net when Leah Pruitt took a pass up the left sideline, beat defender Easther Mayi Kith, and delivered a perfect cross.
