The changeup was Gearrin’s best pitch in 2019 with a pVal of 7.0 on just 135 thrown. It generated weak contact over 85% of the time, so it didn’t matter that his K rate against it was just 12.9%. Gearrin should utilize the change more often in 2020 if he can’t regain the slider’s horizontal movement.
Gearrin’s primary fastball is his sinker but he dropped its usage by 10% in 2019. The sinker has significant armside run and induced ground balls over 60% of the time in 2019. With a just a 4.7% SwStr rate, Gerrin doesn’t generate many strikeouts with the sinker.
Gearrin’s primary breaking pitch is the slider and he throws it 41% of the time. He lost over two inches of horizontal break in 2019 and it significantly lowered his chase rate and SwStr rate. In terms of pVal, the slider went from Gearrin’s best pitch to a slightly below-average offering.
Easily Gearrin’s worst pitch in 2018 with a -4.2 pVal, his sinker showed no promising signs. He rarely fooled batters with it as he walked more opponents (9.2 BB%) than he struck out (6.7 K%), and hitters made contact with the pitch over 88% of the time they swung.
Gearrins best pitch was his slider, which produced an immaculate 38.9% strikeout percentage and an infield fly-ball percentage above 40%. Gearrin would stand to improve if he relied more on his slider and less on his sinker in 2019.
A .341 BABIP helped make Gearrin’s changeup a negative pitch in 2018, but thanks to the lack of velocity separation, it’s no surprise. He did have a stellar swinging-strike percentage, so if he could produce more ground balls, it could become a viable out pitch.
