Giants 10, Cubs 7 (10): Hector Sanchez scored the go-ahead run on a balk in the 10th inning and visiting San Francisco capitalized on a major league record-tying five wild pitches to outlast Chicago.

Hunter Pence hit a solo home run in the ninth to force extra innings and Nick Noonan capped a four-run rally in the sixth with a two-run single for the Giants, who took three of four in the series. George Kontos (1-1) pitched the ninth for the win and Sergio Romo worked around a leadoff double to earn his seventh save.

Shawn Camp (0-1) is the third closer used by the Cubs this season and he became the third to blow a save when he surrendered Pence’s two-out solo blast to center field to knot the score at 7 in the ninth. Camp stayed on for the 10th and allowed back-to-back, one-out singles before forcing in the go-ahead run with a balk and yielding RBI hits to Buster Posey and Marco Scutaro.

Starlin Castro and Nate Schierholtz each belted a changeup from San Francisco starter Tim Lincecum into the stands for two-run homers in the first inning and Alberto Gonzalez added a solo shot in the seventh before pushing across the go-ahead run with a sacrifice fly in the eighth for Chicago.

The Giants took advantage of some wildness from Cubs pitchers to put together a four-run rally in the sixth. Starter Edwin Jackson and Michael Bowden combined to unleash five wild pitches and walk three batters in the frame, and the rookie Noonan’s two-run single put San Francisco on top 5-4.
