"I think if he doesn't start Tuesday, there's probably a good chance he doesn't start again," Hale said. "That's my opinion right now. We'll have to get some input from the doctors and [trainer] Ken [Crenshaw] from that, but it's just hard to believe he's going to be able to start on [Oct. 2]. Just is it worth it?"
Greinke felt shoulder stiffness after his start on Wednesday in San Diego. He then did not travel with the team to Baltimore, instead returning to Phoenix. His MRI showed no structural damage.
"I think it's just a matter of a little swelling," Hale said.
