Desmond made the team in part because we're winning- a decent Zimm first half and he would have been there, likewise, if Desmond put up the same numbers on a team enroute to 100 losses, I doubt he makes it
Not only that, he was selected by the manager because the manager likes him and his ability. Don't get me wrong, he most deffinitely deserves to be there, but let's not go over board. A healthy Zimmy is one of the 3 best 3rd basemen in MLB.
