Not enough bats missed bro, inducing weak contact doesn't cut it here. If his control can remain in the neighbourhood like in the 33 IP out of the pen, then I say his value is in the back end of the pen (huge set up potential). AA will ultimately give him a shot to start just to see what he's got, but it may appear given his command lies within two pitches, his destiny is in the pen. He's young though, so developing secondaries combined with sharpening his composure when adversity strikes is not out of the question, but it's not an easy thing to obtain with any player. He seems to be the type that will thrive in smaller windowed assignments (two innings max). The thing is, there is nothing wrong with that and is extremely valuable.
