Although he has not thrown an MLB pitch in 2017, Collin McHugh threw 10,312 pitches that were tracked by the PITCHf/x system between 2011 and 2016, including pitches thrown in the MLB Regular Season, the MLB Postseason, Spring Training and Fall/Winter Ball. In 2016, he relied primarily on his Fourseam Fastball (91mph), Curve (73mph) and Cutter (87mph), also mixing in a Change (84mph). He also rarely threw a Sinker (90mph) and Slider (85mph).
Basic description of 2016 pitches compared to other RHP:
His fourseam fastball has slightly below average velo. His curve has sweeping glove-side movement, generates a high number of swings & misses compared to other pitchers' curves, has below average velo and has a sharp downward bite. His cutter results in somewhat more flyballs compared to other pitchers' cutters and has strong cutting action. His change generates a very high amount of groundballs compared to other pitchers' changeups and has some natural sink to it. His sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, is basically never swung at and missed compared to other pitchers' sinkers, has less armside run than typical and has slightly below average velo. His slider (take this with a grain of salt because he's only thrown 15 of them in 2016) generates more whiffs/swing compared to other pitchers' sliders and has less than expected depth.
