https://arizonasports.com/story/2101344/diamondbacks-part-ways-with-pitching-coach-mike-butcher/Furthermore, several pitchers saw regression during Butcher’s tenure, especially in 2019. Yoshihisa Hirano’s ERA went from 2.44 in 2018 to 4.75 in 2019. Andrew Chafin’s ERA increased year-over-year by more than half a run. Robbie Ray posted his worst ERA in three seasons.
