WASHINGTON (AP) - Pinch-hitter Hector Sanchez hit a three-run homer with two outs in the ninth inning, helping the San Francisco Giants beat the Washington Nationals 4-3 on Thursday.

Down to his last strike, Sanchez connected off Nationals closer Rafael Soriano (2-3) on a full-count pitch. The drive landed just inside the right field foul pole in the second deck.

Sergio Romo worked a scoreless bottom half for his 29th save. Javier Lopez (2-2) pitched 1 2-3 scoreless innings of relief to earn the win.

The loss snapped Washington's five-game winning streak and spoiled Dan Haren's six-inning, one-run effort.

Ian Desmond doubled home two runs and Jayson Werth added two hits for the Nationals.
