Hart's speed would be wasted at first base. I know he's not the best right fielder, but he is still learning the position and, in my opinion, getting gradually better at it. His speed allows him to get to balls that players like Gross would not even come close to. His arm strength isn't all that great, but if he works on his accuracy, he could be an above average defender. I know this last month has been miserable for Hart, but given the team's situation, I feel it's been an anomaly. I think Hart's value is in the outfield. Maybe they move him to left or center, but first would be a waste of his talent.
