San Diego Padres
Although he has not thrown an MLB pitch in 2019, Garrett Richards threw 12,404 pitches that were tracked by the PITCHf/x system between 2010 and 2018, including pitches thrown in the MLB Regular Season and Spring Training. In 2018, he relied primarily on his Slider (90mph) and Fourseam Fastball (96mph), also mixing in a Sinker (97mph) and Curve (82mph). He also rarely threw a Change (91mph).
Basic description of 2018 pitches compared to other RHP:
His slider is thrown extremely hard, has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders and has primarily 12-6 movement. His fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is straight as an arrow and has well above average velo. His sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, is blazing fast, has surprisingly little armside run and generates more whiffs/swing compared to other pitchers' sinkers. His curve has an exceptional bite and is slightly harder than usual. His change (take this with a grain of salt because he's only thrown 1 of them in 2018) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has an obvious armside fade, dives down out of the zone and results in more flyballs compared to other pitchers' changeups.
