Yankees right-hander A.J. Burnett struggled yet again on Saturday night in a 9-4 loss to the Twins. Burnett didn't make it through the second inning at Target Field. "I've got to be better, and I know that," Burnett said. The starter shouted a few curse words while leaving the mound, upset at a call that gave Joe Mauer a walk to load the bases. On the television screen, Burnett appeared to be angry at manager Joe Girardi, but both men vehemently denied any tension between them afterward. "I'm tired of people looking for something between me and A.J.," an irate Girardi said after the game. "Me and A.J. have mutual respect for each other. I cheer for this guy. He cheers for me, and we cheer for this team. I want the guy to do well." Burnett was charged with seven runs for the second time in his last four starts, giving up five hits and three walks while recording only five outs.
