Mike Hampton, who signed one of the richest contracts in baseball history but hasn't pitched for the Atlanta Braves since 2005 because of injuries, hurt his right hamstring during the first inning of his very first start in the Mexican Winter League. The former 20-game winner will need up to a month to recover, which ends his stint south of the border. The Braves now must wait until February to get a realistic assessment of Hampton's chances of returning to the mound. "There's still some questions, and we don't have all of them answered," General Manager Frank Wren said Tuesday. "We'll have to wait until spring training for those answers." The Braves are encouraged by Hampton's recovery from two straight elbow surgeries, having watched him throw in the Arizona Fall League. But unlike last season, they aren't penciling him in as a member of the rotation.
