ATLANTA — Tom Glavine says he felt no pain in his first time throwing off a mound since inflammation was found in his left rotator cuff last month.

Glavine threw for about 15 minutes in the Braves bullpen on Monday. He said he wasn't "trying to do anything spectacular the first time" but said he was able to throw "without any pain inhibiting me from doing what I wanted to be doing."

On April 14, Glavine said he may retire if pain continued in the left shoulder.

The 43-year-old Glavine said he plans to throw another side session on Friday and then possibly plan one or two minor league rehab starts.

Glavine was 2-4 with a 5.54 ERA in 13 starts last season. He had offseason surgeries on his left elbow and left shoulder.
