GLENDALE, Ariz. -- Jake Peavy played catch on Tuesday and said he is encouraged about the way his right rotator cuff has responded to treatment.
"I felt quite a bit better than I did a few days ago," Peavy said, "so I was excited that things are certainly calming down.
"To see it in just a couple days make a drastic improvement is very encouraging.''
Peavy tossed the ball about 35-40 feet for about five minutes with coach Juan Nieves. He said he plans to play catch again on Wednesday, including stretching it out with long toss and "push it as far as we can without pushing it.''
A day after throwing 83 pitches in his fourth start on Sunday and looking like a near sure-thing to make the opening-day roster, Peavy revealed that he had tendinitis in the rotator cuff. He received treatment and took the anti-inflammatory Celebrex.
Peavy said he won't pitch in a game until he is completely healthy.
"When I take the mound I will be as healthy as I can possibly be,'' he said. "I don't know that means and not making any predictions about what will happen but I will go out there 100 percent healthy.''
Peavy said he'll play catch today as long as he feels well enough. He expects that to be the case. He hopes to possibly throw off a mound at the end of the week.
Phil Humber is taking Peavy's turn in the rotation Thursday against the Cubs and is slated to start the fifth game of the regular season in Kansas City on April 6.
