Matt Cain quieted the Nationals' bats through four innings until Bryce Harper unleashed a towering home run to right-center field to cut the Giants' four-run lead to one.
MOMENTS THAT MATTERED
Double trouble: The Giants' Brandon Crawford, Justin Maxwell, Gregor Blanco and Duffy hit two-baggers as part of a four-run second inning. The feat matched a Giants' San Francisco-era record for most doubles in an inning, according to Elias Sports Bureau.
Harper leads the charge: The Nationals made it a one-run game in the fifth inning by scoring four runs.
