Anderson to DL, Rosales playing SS

Brett Anderson was placed on the disabled list today with tendinitis in his left elbow after he had a contrast MRI. Calling it relatively good news, manager Bob Geren said Anderson will not throw until he’s symptom free and then he’ll start back up again. Anderson won’t be throwing for at least 2-3 days, but Geren is hopeful that the left-hander can begin a program before too long. Geren said Vin Mazzaro is filling Anderson’s slot in the rotation.

In other moves, catcher Landon Powell was optioned to Sacramento and relievers Cedrick Bowers and Henry Rodriguez were brought up. Geren wanted a little more depth in the bullpen considering how much he had to use his relievers on the road trip.

Mired in a 1 for 32 slump at the plate, Cliff Pennington is not starting tonight at shortstop. Adam Rosales will play that position, with Geren saying Rosales might even play first base some time soon. Pennington will be back in the lineup tomorrow though.

Andrew Bailey is “50-50” for tonight’s game after throwing two innings yesterday. Geren said Eric Chavez is doing better and may join the A’s early next week for workouts.

After his collision with Mark Ellis yesterday, Ryan Sweeney said he didn’t sleep that well last night but started to feel better as the day went on and is back in the lineup.
