The San Francisco Giants hadn't scored a single run while right-hander Ryan Vogelsong was on the mound in his five previous starts at AT&T Park. Buster Posey became the first catcher in Giants history to record two five-hit games, contributing a triple and four singles to a 19-hit attack that overpowered the Milwaukee Brewers 13-2 in the opener of a three-game series. Second baseman Joe Panik had a double among his four hits, center fielder Angel Pagan and right fielder Hunter Pence added three hits apiece, and left fielder Gregor Blanco belted a two-run homer for the Giants, who recorded season highs in runs, hits and margin of victory. The win was San Francisco's fourth in a row and allowed it to pick up a game on the National League West-leading Los Angeles Dodgers, who lost in 12 innings in San Diego.
