EDGE Analysis

Watson has yet to pitch in an exhibition game this spring because of tightness in his left shoulder. The 34-year-old is expected to serve as the Giants' closer on Opening Day, however manager Gabe Kapler has suggested the possibility of an open competition during camp. Right-hander Trevor Gott has emerged as Watson's main competition for the job to begin March.
