I would say he is more likely to strain something running down the first baseline then fielding IMO I could be wrong I don't want to say but if there is no inflammation and no pain whether he starts today or Monday really makes no difference.
Does not really matter he is going to be playing on Turf come Monday 2 days is not going to be the difference between the f***ing 60 day DL and being healthy lol. A wee bit of an over reaction.
