Joba Chamberlain is preparing for his role in New York's revamped bullpen. Chamberlain threw 30 pitches off a mound Wednesday during his first full pre-spring training workout at the team's minor league complex. "Anywhere from the sixth inning on, I would assume," Chamberlain said when asked of his role. "I've got to embrace it and try to do the best I can to help us win another championship. We've got a pretty good bullpen. It's going to be fun out there with those guys."
