Everything Lorenzen throws is fast. Really, really fast. Unfortunately, not many of his pitches move much, which is why his strikeout numbers lag behind what one might expect from his raw velocity. Second image above is from 2015, when he mostly started, and the third image is from 2017, when he was exclusively a reliever.
Outlook
Michael Lorenzen has been a star college outfielder, a two-way player, a first round draft pick, a top pitching prospect, a major league starting pitcher, a bum elbow, a shutdown reliever, a two-way player again, and a possible major league starting pitcher again.
