Braves' McCann undergoes shoulder surgery

Atlanta Braves catcher Brian McCann had surgery Tuesday to repair a troublesome right shoulder that hindered the six-time All- Star throughout the 2012 season.

Team orthopedic surgeon Dr. Xavier Duralde performed a procedure to the posterior portion of McCann's shoulder. The Braves do not have a specific timetable for a recovery as of yet, so it's therefore unknown whether he'll be ready for the start of next season.

McCann hit 20 homers and drove in 67 runs over 121 games this past year, but batted a career-low .230 while battling through several subluxations of the shoulder.

Atlanta holds a $12 million option on McCann, a lifetime .279 hitter who's hit 20 or more homers in six of his eight major league campaigns, for the 2013 season. The team has until three days after the World Series to decide whether to exercise the clause.
