Regression just never really hit for Castillo last year, despite a walk rate of 10.1%, fourth-worst in the league among qualified pitchers. There's no doubting Castillo's stuff, particularly his devastating changeup, and the Reds should be more competitive than they have been in years. But he simply has to cut down on the free passes if he wants to build on his breakout 2019. There's every reason to think he will as he continue to grow as a pitcher, and should make a reliable second fantasy starter.
