Brian Roberts left Baltimore's loss to the New York Yankees in the second inning Tuesday night with a dislocated left elbow, ending a breakout season for the All-Star second baseman. Roberts was covering first base after New York's Bubba Crosby bunted with Bernie Williams on second. First baseman B.J. Surhoff rushed in to field the bunt and his throw to Roberts arrived at about the same time Crosby did. Crosby crashed into Roberts' outstretched left arm, snapping it back. Roberts dropped the ball and went to the ground in tremendous pain, allowing Williams to jog home from third. "Nobody really knew what to do," Surhoff said. "Bernie didn't, Crosby didn't, I didn't. After a little while it was pretty obvious something was wrong."
