SAN FRANCISCO (AP) - Buster Posey hit a two-run homer and Matt Cain bounced back from two rough starts to earn his first win in more than a month as the San Francisco Giants beat the first-place Arizona Diamondbacks for a second straight night, winning 4-3 on Saturday night.
Posey connected for his 14th homer in the fifth inning. Cain (6-6) allowed two runs in five-plus innings after failing to make it out of the third inning his last two starts to win for the first time since June 13 at Pittsburgh.
With wins in the first two games out of the All-Star break, the World Series champion Giants have cut their deficit in the NL West to 4½ games behind Arizona. The Diamondbacks' lead over the Los Angeles Dodgers fell to a half-game as Wade Miley (6-8) lasted just four innings.
