Reddick is a first class professional who excels in every aspect of the game. Even when he isn't hitting he is making a positive contribution. I am guessing that he is one of the most if not the most respected player on the team among the players. I don't see Hinch replacing him absent injury or a deep, prolonged slump. Maybe a few days off would bring his hitting around.
I'm all for having him back for the final year of his contract. If Tucker can beat him out, fine but I am not for trading him and handing the job to Tucker.
For what its worth, in every game he broadcasts, Berkman makes it a point to highlight Reddick's professionalism and importance to the team.
