Kelly was on Arizona’s injury list due to an intercostal nerve irritation that he suffered during spring training. If the 37-year-old is to start on Tuesday night, it’ll be his first appearance with the Diamondbacks since making his way back to the team after getting traded away to the Texas Rangers last season.
