Daric Barton (shoulder) said he might receive a second cortisone shot on Monday. He's evidently already had one for his shoulder, and he could get another one due to some biceps tightness. Barton underwent surgery in September to repair a partial labrum tear, and he's obviously not totally recovered from the procedure. He's not expected to throw until mid-March, but, at this point, he doesn't appear to be in danger of missing Opening Day.
