I know that I've always been worried about the way Bush releases the ball, either out of the wind up or the stretch. He holds the ball out away from his body and does a very subtle little flick of the wrist and pretty much shows the hitter, the bench, and anybody watching closely on television what pitch is coming. He doesn't hide it well at all in my opinion. I realize that Prior has the same kind of motion (minus the little flick of the wrist) but has been more successful, I think, because (a) he hides the ball a bit better, and (b) he just has more "stuff" in his arm (although that's debatable, too, with his injury history--but let's not debate that, okay?). I wouldn't be surprised if he's hurt and trying to pitch through it, but I'm not a doctor. So I'll just go on and hope that it's just the idea of his arm needs to be stretched out some more.
