Martinez was able to play catch and was hoping to take some batting practice on Tuesday. He wasn't sure if he'd able to catch on Wednesday night. He did, however, say that he could help in an emergency situation on Tuesday if something happened to Jason Varitek.
"I'm a lot better, a lot better than I expected. I've been putting more weight on it," said Martinez.
Without Martinez, J.D. Drew batted third for the Sox on Tuesday. Varitek hit eighth.
