Jason Isringhausen (back) said Tuesday that he is not close to returning. Isringhausen received an injection Monday to attempt to alleviate right leg numbness associated with a herniated disc in his lower back. He was able to play catch Tuesday, but his status remains in a state of limbo at the moment. Bobby Parnell and Manny Acosta should continue to get most of the late-inning work in the interim.
