Papelbon is an interesting beast. He was most effective when he elevated his fastball. Looked like it was coming down the middle, but ended up unhittable at the letters. Recently, hitters have been laying off his higher FB, forcing him to come into the zone with it. That's the thing about the bigs. Very few players can be 1 trick ponies, which is why Paps is breaking out his slider a bit more than I have seen it in the past. The problem is, his control isnt that great to begin with, and now that he has to come into the zone more often, he is being exposed to some degree
