LOS ANGELES -- - Pinch-hitter Andrew Susac singled home the go-ahead run in the 13th inning, and the San Francisco Giants beat the first-place Los Angeles Dodgers 5-2 Monday night to climb within 3 1/2 games of the NL West lead. Susac singled to left field off Kevin Correia (2-4), scoring Brandon Belt. San Francisco tacked on two more runs to take a 5-2 lead on Gregor Blanco's double. Blanco homered and scored twice for the Giants, who snapped a three-game skid and remained tied with Pittsburgh for the two NL wild-card slots.
