He was pumping 96 at the end of last season. WTF happened
Re-injured his arm? Perhaps the elbow was the first thing to go, but maybe his shoulder is at fault? Any way you slice it, we are all just Monday Morning doctoring on this, and the end result is that his results might not be what they once were. If he can return to at least being effective, he has a spot, but if not, as with other bullpen arms, you just move on.
