He's got starter's stuff with a 90-95 MPH fastball with movement, a legit outpitch with his curveball/slider, and he's got good arm action for a changeup. He gets groundball, has a pitchers build, and has an athletic windup to boot.
I think the Cubs are very high on him, and I'd argue he's our best prospect. He's got front of the rotation stuff type ability. Seems like one of those guys who can put it all together next year and fly up rankings. It's possible he gets called up, but I'm not sure what I think about it yet. If he's doing well, then sure.
