A’s beat Giants 5-0 in opener of Bay Bridge Series

Jesse Chavez continued an impressive run of A’s starting pitching with six scoreless innings, and Alberto Callaspo contributed a two-run double Monday night as Oakland beat the Giants 5-0 in the opener of the Bay Bridge Series.

In front of an announced sellout crowd at Coliseum, Chavez matched his career high by striking out nine and did not allow a runner past second base. In five games on this homestand, A’s starting pitchers have combined to throw 33 innings, allowing three runs and 19 hits and striking out 33.

Ryan Vogelsong matched zeros with Chavez until the fifth, when Craig Gentry was hit by a pitch and eventually scored on John Jaso‘s groundout. Vogelsong then plunked Josh Donaldson with an inside fastball to start the sixth and was relieved by Juan Gutierrez after allowing a one-out single to Jed Lowrie. Callaspo lined Gutierrez’s first pitch into the gap in right-center for a double that scored both runners.

The A’s beat the Giants for the 10th time in their last 12 games in Oakland and improved their interleague record this year to 8-1, best in the majors.

A’s notes – Manager Bob Melvin confirmed Jason Hammel, the other pitcher acquired in the Jeff Samardzija trade with the Chicago Cubs, will start Wednesday. Hammel arrived in the Bay Area on Sunday night and threw a bullpen session before Monday’s game.

Hammel, a right-hander who was 8-5 with a 2.98 ERA in 17 starts for the Cubs, said he was “shocked” going from last-place Chicago to the first-place A’s. He also said he thinks the trade “shows the (A’s fans) that we’re looking to take this thing.”

Hammel is looking forward to having his home games at the pitcher-friendly Coliseum.

“I’ve had Coors Field, I’ve had Camden Yards, Wrigley (Field) – all launching pads,” he said. “So I welcome the challenge of pitching in an actual fair ballpark.”

To clear Hammel’s roster spot, the A’s designated left-hander Brad Mills for assignment.

• Josh Reddick (hyperextended left knee) went through full pregame activities, including outfield drills and running for the first time since his injury. Left-hander Drew Pomeranz (fractured right hand) has been cleared to start catching a ball with his glove hand.

Giants notes – Pablo Sandoval was held out of the lineup because of swelling in his left elbow, where he was hit by a pitch Saturday. Manager Bruce Bochy said an X-ray was negative, “but (the elbow) just has not calmed down as much as we’d hoped,” adding Sandoval remains day-to-day.

• Marco Scutaro played second base Monday night for Triple-A Fresno and has told the Giants he’s ready to return, Bochy said, though that’s likely not imminent.

“He needs playing time,” Bochy said. “He needs at-bats. He’s missed so much time. He’s got to play nine innings; he hasn’t done that yet.”

• Angel Pagan (back) will report to Arizona to begin rehabilitating and likely will start baseball activities Wednesday. The Giants do not expect him back until after the All-Star break.
