Roger Clemens got banged up by the Mariners, and then quickly left the clubhouse after the Yankees' 7-1 loss on Monday to get an MRI exam on his balky right elbow. The 45-year-old Clemens, who allowed five runs and eight hits in four innings to lose for the first time since July 28 at Baltimore, felt his elbow tighten up during the game, manager Joe Torre said. "First three innings it was a manageable situation for him and then it started to tighten up," Torre said. "Hopefully it's just something that needs a little rest." Clemens, who was already gone before the clubhouse opened, was unavailable to comment.
