Yankees pitcher A.J. Burnett has some explaining to do. On Saturday, the right-handed star fumbled a start against the Tampa Bay Devil Rays—only the latest in a string of poor showings—and took out his frustration by punching a clubhouse door with both hands. Now he’s got lacerations on both hands, and it’s unclear if he’ll be able to make his next start on Friday. Burnett apologized to his teammates, but declined to share any details of the mea culpa. “It’s over and I learned from it, and hopefully everybody else learned from it.” Teammate Derek Jeter agreed that the matter is a private issue: Burnett “doesn’t have to address it with anyone in the media,” he said. The pitcher is reportedly performing well in the bullpen despite the injury.
