It wasn’t as lopsided as the notable Bay Bridge encounter 25 seasons ago, but the concluded A’s-Giants series was decidedly for the Athletics.

The Giants fell flat again in a 6-1 loss at AT&T Park, a performance that looked all too familiar. San Francisco’s offense has disappeared, scoring just 40 runs over their last 18 games, which covers most of a month of bad baseball that’s seen them drop 15 of 19 at home.

Josh Donaldson homered off Tim Hudson in Oakland’s four-run sixth inning that put them up 6-0. In a meeting of free agent starters acquired in the off-season, Scott Kazmir was the winner, his 11th that puts him line for a possible start in Tuesday’s All-Star game while Hudson dropped his fourth straight decision.

“There were a couple bad pitches that they took advantage of, and they hit a couple decent pitches, I thought,” Hudson said. “I don’t really know what to say. Kind of unraveled on us a little bit.”

Kazmir kept the Giants’ bats stymied with nine strikeouts that had the Giants looking tentative at the plate. Manager Bruce Bocy provided some inight into why his team’s offense struggled, while acknowledging Kazmir and Oakland, who continue to lead all of baseball with a 58-34 record.

“It just looks like we’re caught in between as an offensive group. Late on fastballs, out in front of off-speed pitches,” Bochy assessed.

“It was a tough series, but we’ve played a good club with a great staff. The guy we faced today, he’s on the All-Star team, so a lot of clubs haven’t done well against him. Still, we need to find a way to plate some runs.”

The Giants fell a game back of the Dodgers when they won Thursday night in Dodgers Stadium, 2-1 over the Padres. The rivals are even in the loss column, even as the Giants have slumped horribly and next meet July 25 with Marco Scutaro and possibly Angel Pagan both back in the everyday lineup.
