I was piled on Twitter by a lot of the fanboy/fangirl for saying this last year, but an injury is the best case scenario for Cabrera.
I reject the notion that he isn't blocking anybody. There's an outfield glut building, and if things go well you need a spot in the lineup for Greene, Tork, Carpenter, Baddoo, and Meadows. If the player dev machine picks up and there is somebody OPS-ing 1000 in Toledo, it hurts to not be able to give that person a chance because you have a sub replacement every day DH standing in the way.
Oh yeah, the above happened with Carpenter this season, and he didn't get the chance until Cabrera was IL'ed.
