A utility player that can play every position is really useful with limited bench spots due to large pitching staffs. For example at the start of the year with a backup catcher, Arcia, Nunez and Santana on the bench (Park at DH). But he is still a utility player and he shouldn't be playing often since he isn't a great hitter or really good defensively at any spot. His role should be the last man in instead of starting half of the games. He also has more value when you have Park at DH, Sano in RF and Arcia in LF which results in very little roster flexibility. He has less value with Grossman, Kepler, Buxton and Rosario playing the 3 OF spots since they can all play CF. He definitely isn't blocking Polanco if he was used correctly (last man to be used).
