OAKLAND — Jesse Chavez matched a career high with nine strikeouts in six innings, and three relievers pitched scoreless ball to lead the Oakland Athletics past the San Francisco Giants 5-0 on Monday night for their fifth straight win.
Alberto Callaspo hit a two-run double, and three others drove in a run to power the A’s in front of an announced sellout crowd of 36,067 festive fans.
The Coliseum had a colorful sprinkling of green and gold from Oakland revelers mixed with the orange and black of San Francisco supporters for the Bay Bridge Series opener.
Chavez (7-5) allowed four hits and two walks to help extend the A’s record to a major-league best 56-33. Fernando Abad, Dan Otero and Ryan Cook shut down San Francisco the final three innings.
Ryan Vogelsong (5-6) lost his third straight start for the Giants, who had just five hits.
The right-hander gave up five hits and three runs in 5 1-3 innings. He struck out four, walked two and hit a pair of batters, leading to Oakland’s first two runs.
The banged-up Giants had lost 18 of 23 to fall out of first place in the NL West — where they once held a 9½ game lead over the Dodgers — but showed signs of coming out of their slump by winning two in a row at San Diego over the weekend.
Instead, the two-time defending AL West champion A’s put together the kind of all-around effort they’ve had most of the season to swipe the Bay Area headlines from the Giants again this summer.
Oakland started its scoring surge after home plate umpire Paul Nauert ruled Craig Gentry was hit by a pitch on his hand leading off the fifth. Giants manager Bruce Bochy challenged the play, which was upheld after a video review.
Gentry stole second, advanced to third on Coco Crisp’s bunt single, and scored on John Jaso’s groundout for the A’s first run.
Josh Donaldson also was hit by a pitch by Vogelsong on his left hand leading off the sixth. Nauert asked first base umpire Angel Hernandez if Donaldson swung at the pitch, and Hernandez signaled no. Bochy had a heated conversation with Nauert after the call.
Callaspo came through later in the inning with a two-run double off Juan Gutierrez to extend Oakland’s lead to 3-0. Brandon Moss and Donaldson each drove in a run off Gutierrez in the seventh after Giants shortstop Brandon Crawford committed two throwing errors.
The teams will play in Oakland again on Tuesday night before the series shifts to San Francisco for the final two games.
