It is early, but he's keeping the good K/BB ratio (5Ks, 1 BB). If he can stay close to a K/9, I think he'd be added to the 40 man roster at the end of the year, and might even get a call up when there is a house cleaning. 2:1 ground ball / fly ratio also is nice.
What does he profile as now, a righty match up middle reliever? MiLB.com only has his righty / lefty splits in harrisburg, and his success is so short that I don't know if a meaningful judgment can be made on whether he can get out lefties. Was that his problem as a starter? Baseball-reference does not have spilts.
