SAN FRANCISCO - Barry Zito and Chad Gaudin combined on a six-hitter, Buster Posey homered and the San Francisco Giants beat the San Diego Padres 5-0 on Sunday to complete a three-game sweep.
Zito (3-1) bounced back from the worst start of big league career to defeat the Padres for the first time in nearly two years. He allowed five hits in seven innings, struck out four, walked one and did not give up run for the third time in four starts.
Posey's first home run of the season was just the 11th this year for the power-starved Giants.
Before the two-out, two-run drive off Eric Stults (2-2) in the fifth, Hunter Pence, Pablo Sandoval and Brandon Crawford had accounted for all of San Francisco's homers.
The Padres (5-13) return to San Diego on Monday to start a series against the Milwaukee Brewers.
