A's sweep Giants

Bruce Bochy could take some solace in seeing more competitive at-bats from his slumping San Francisco Giants.

Still, that doesn't make getting shut out for the second straight day any easier to accept.

Jake Fox hit a go-ahead RBI double in the seventh inning and the Oakland Athletics completed a three-game sweep of the visiting Giants in the Bay Bridge Series with a 3-0 victory yesterday.

The Giants, held to one run all series, stumbled to their season-high fifth straight loss despite Bochy shaking up his lineup in an effort to get out of this rut.

"It's really, really tough. It's frustrating," catcher Bengie Molina said. "It's very sad. Everyday we go out there and don't score and this pitching staff pitches the way they do, it's a waste."

Adam Rosales led off the seventh with a single against Jonathan Sanchez (2-4), Mark Ellis sacrificed and Fox followed with the double. Kurt Suzuki and Ryan Sweeney each singled in an insurance run in the eighth.

Oakland swept San Francisco for the fourth time in the last 10 series between the clubs and first at the Coliseum since June 24-26, 2005. The A's earned a three-game sweep in San Francisco in 2008.

This marked the second straight pitcher's duel of the series after Oakland's Gio Gonzalez beat Matt Cain, 1-0, on Saturday. Cain pitched a complete game and Oakland managed only an unearned run to win.

Sanchez received no run support for the fifth time in his nine 2010 starts.

Ben Sheets struck out eight in six scoreless innings but left with the game scoreless. The A's $10 million ace faced the minimum through three, allowing Pablo Sandoval's two-out single in the first only to get the slugger on a caught stealing.
