I often pick him in the 21st and last round in Yahoo live drafts. The guy has got a great arm and will have a K/IP ratio around 1.0 but of course drawbacks could be a low win total (on a bad team) and a high whip and era (rookie). But it doesn't hurt to take him with your last pick as your worst SP is usually a replacement level player anyways and can be replaced off of the waiver wire pretty easily if need be.
