After he spent all of 2017 in the minors, Hutchison’s MLB return featured a four-seamer that clocked in three ticks below his 2015 rate, and the pitch was full of problems. The O-swing% and SwStr% were down significantly, which led to a major decrease in K% (19.5% in 2016, 9.5% in 2018) and major increase in BB% (12.0% in 2016, 19.0% in 2018).
Hutchison lost two ticks on his slider and added a little vertical movement in 2018. Overall, the pitch’s performance (-2.7 pVal) was in line with previous seasons, which is not a good thing.
As the year went on, Hutchison faded his changeup usage (25% in April, 10% in August). The pitch had OK results, featuring the highest chase and swinging-strike rates of his career, but it also allowed a .296 batting average against. The pitch has similar movement to the two-seamer, but as he only threw his two-seamer 32 times last year, combined with the fading usage, the changeup won’t be a major player in Hutchison’s arsenal.
There was a small sample size on the two-seamer, but after it allowed a .714 ISO and .652 wOBA, don’t expect that usage to increase.
