In 2015, Zack Godley made his debut in the Majors. On a basic level, his 3.19 ERA was the best of the Diamondbacks’ starters. On an advanced level two stats, K% and GB%, showed an unusual simultaneous excellence in both those statistics.
In 2016, he had a small second-season regression (which is common) before 2017 when he reached his zenith. On a basic level, his 3.37 ERA was great, although starters Robbie Ray and Zack Greinke pitched even better! On an advanced level, K% and GB% continued to shine.
