If one didn't know better, Brian McCann as if he might step up to the plate and compete with Chipper Jones and others in the home-run contest Saturday at McCann's Rally Foundation celebrity softball game at Coolray Field.

But under the softball jersey were scars from Oct. 16 right-shoulder surgery. McCann was left smile, shake hands and thank all the participants and fans who came out for the annual event to raise funds for childhood cancer research.

"I should probably be wearing [a sling] out here, but I'm being careful, I'm not going to do anything dumb," he said, before going to have his picture taken with Rally Foundation kids.

Five days after having his $12 million team option for 2013 picked up by the Braves, and less than three weeks since surgery, McCann was more upbeat than for most of the final months of his career-worst season, when his shoulder was throbbing and he tried to play through it.

He faces about six months of rehab and could miss the first month of the 2013 season, though the Braves are optimistic that he might be back a little sooner. For now, McCann is doing range-of-motion exercises with Braves physical therapist Lloyd van Pamelen.

"Everything, from what he's telling me, looks really good," McCann said. "I've never had surgery, so it's hard for me to compare it to anything. But I've always healed pretty quick. I feel good about where I'm at, being two weeks out of surgery I feel really good."
