It depends in part on how your evaluations are set up. For instance, compared to all players or compared to players of that position. In this case, I'd wager it's compared to his position, and while you may think he possesses really good basic pitching ratings, I'd argue he's below average. His control is questionable, his movement is okay, his stuff is certainly there, but his stamina is such that he can't face very many batters before tiring and, frankly, doesn't have the pitching tools to be a good closer, stuff aside. His actual pitch ratings aren't too bad, actually, but given his very limited use, along with a stint in AAA, I'd say managers are regularly finding better candidates to utilize.
