Fangraphs said he has a really good changeup and slider but if you look at his Statcast it says he throws the following: Four Seamer (37.4%), Changeup (17.2%), Curve (16.9%), Sinker (14.5%), Cutter (14%). Last year both his Changeup and Slider looked really good. Is he really not throwing a Slider this year or is Statcast not that reliable for labeling pitch types correctly?
Because it looks like his curveball is pretty effective too. Just has a crap fastball. If he threw the Fastball even less and threw his other pitches more perhaps he could be a backend guy.
Regardless, he's a much better option for us than Richard or Jackson.
