Brett Anderson likely to miss about five weeks; other A’s pregame news

The official word on left-hander Brett Anderson: He’ll be shut down for two weeks with his forearm strain and then resume throwing. If things go well at that point, you figure it will take him anywhere from 2-3 weeks to get his arm back to major league-ready. So I’d say we’re looking at approximately a 5-week absence for the A’s lefty.

Yesterday’s MRI showed Anderson has a strain in the musculotendinous junction (raise your hand if you’d heard of that one before). Basically, it’s the area where the muscle and tendon meet in the forearm.

Bottom line, the news could have been worse. But manager Bob Geren didn’t want to get overly optimistic about the diagnosis. “We’ll just have to see when he starts throwing how he does,” Geren said before batting practice.

And he still isn’t revealing who will start Friday in Anderson’s place. Trevor Cahill or Vin Mazzaro figure to be called up from Triple-A Sacramento to pitch that game.

–We almost made it to game time without another injury to report. Kurt Suzuki was in the lineup, but he was just scratched. Jake Fox will replace him at catcher. No word on what’s bothering Suzuki, but it’s reasonable to assume his back trouble of recent days is acting up. This will be the fourth straight game he’s out of the lineup.

–Cliff Pennington leads off for a third straight game, with Rajai Davis sitting again. Geren said the right-handed hitting Davis is likely to start tomorrow against Toronto lefty Ricky Romero. Davis, who’s been slumping for about two weeks, said he doesn’t think there’s anything mechanically wrong with his swing. “It’s totally a mental thing, something that I expect to turn around very shortly,” he said.

Geren indicated outfielder Matt Carson might get a start tomorrow night as well.
