"It felt better," Ortiz said Tuesday after batting practice. "I got that injection yesterday and it actually felt pretty good last night. It felt like I could play last night. I got a little excited. But it was just six to eight hours, and then it goes back to normal and do what it's supposed to do, and get that inflammation out of there."
Ortiz has been out since July 16 with a right Achilles strain. Wednesday is scheduled to be Ortiz's first day of full activity, and that will serve as a test. He said he doesn't expect to go out on a rehab assignment.
"He says he feels as good now as he did before he got hurt," manager Bobby Valentine said.
Ortiz said he still has a little sensation in his heel but that it's improving.
The team entered Tuesday night's game against the Rangers 9-11 in Ortiz's absence.
"Trust me, I'm dying," Ortiz said. "I want to be playing. It's not fun, watching. Especially knowing this ballclub needs me the most. Every time we win a game it makes me feel better. It makes me feel more comfortable and takes some of the pressure off myself. Those games you see we lose one or two runs, it gets in your head a little bit because you think you could have done something. It's an ugly truth and I have to deal with it."
