SAN FRANCISCO (AP) - Ian Desmond singled in Bryce Harper in the 10th inning, and the Washington Nationals beat the San Francisco Giants 2-1 on Wednesday to avoid a three-game series sweep.
Harper sparked the winning rally with a one-out double. Ryan Zimmerman was walked intentionally before Desmond came up with his big hit against Jeremy Affeldt (1-1).
Tyler Clippard (3-1) pitched a perfect 10th for the win and Rafael Soriano got three outs for his 14th save. He failed to convert each of his last two chances, including Tuesday night's 4-2 loss.
Buster Posey hit a tying RBI single for San Francisco in the eighth.
