Daric Barton (shoulder) is planning to swing a bat Thursday and could play in a spring game Friday. Barton was shut down for the past couple of days after getting a cortisone injection Monday in his troublesome right shoulder. The 26-year-old first baseman is hoping to avoid further setbacks and will try to fit in enough at-bats before the start of the 2012 regular season. If he indeed plays in Friday's game, he'll be right on track.
