The Fangraphs scouting report on him when drafted:
Ottenbreit is a super-projectable righty with low-90s velo right now and a more advanced curveball/changeup complement than is typical for a cold weather high schooler. While his stuff quality is advanced, that descriptor does not extend to his command. Pitches often sail on him, up and to his arm side. He needs to develop control several grades better than he currently has just to be a reliever, but Ottenbreit has starter-quality stuff and fits in with the $1 million prep arm archetype that typically falls toward the top of the 40 FV tier on our lists.
Clearly TJ surgery set him back almost 2 years, but hopefully the projections around him still stand. In our second tier starting pitching prospects (Painter and Abel are the first tier now) he probably ranks behind Klassen and Cabrera and Aldegheri, but after that he is as good as anyone else. McGarry and Pan could be headed to the bullpen. Then there is a group of McFarlane, McGowan, and probably Ottenbreit. Maybe Alexis De La Cruz too in that group. Pitchers that rank in our 20-40 range and might start.
