Update (8:43pm): The MRI revealed a “small persistent strain” of the left groin, and Andy will not throw off a mound for another week. He will continue to throw off flat ground, however.
6:17pm: Via Marc Carig, Andy Pettitte is going for an MRI on his injured groin, saying he still feels a “pull” when he tries to pitch at game intensity. Even if the MRI comes back clean, I can’t say I’m optimistic that he’ll be back before mid-September. Perhaps his rehab was too aggressive, too early, but we can’t say for sure.
