A’s shut down Jesse Hahn with forearm injury


A’s right-hander Jesse Hahn will be shut down for at least two weeks and placed on the disabled list after being diagnosed with a strained forearm.

Hahn hasn’t pitched since July 1 and his arm responded poorly to a recent bullpen session, at which point the A’s sent him for an MRI exam. Obviously a strained forearm is better news than structural damage, but given Hahn’s history of arm problems it’s still very worrisome.

Acquired from the Padres in the Derek Norris deal this winter, Hahn has started 16 games for the A’s with a 3.35 ERA and 64/25 K/BB ratio in 97 innings.
