Felix Hernandez has thrown 35,485 pitches that have been tracked by the PITCHf/x system between 2007 and 2018, including pitches thrown in the MLB Regular Season, the MLB Postseason, The World Baseball Classic and Spring Training. In 2018, he has relied primarily on his Sinker (90mph), Curve (80mph) and Change (86mph), also mixing in a Fourseam Fastball (90mph) and Slider (84mph). He also rarely throws a Cutter (89mph) and Slow Curve (72mph).
Basic description of 2018 pitches compared to other RHP:
His sinker has slightly below average velo. His curve is a prototypical pitch with few remarkable qualities. His change dives down out of the zone, has slight cut action, is slightly firmer than usual and results in somewhat more groundballs compared to other pitchers' changeups. His fourseam fastball has less armside movement than typical, has some natural sinking action, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly below average velo. His slider is basically never swung at and missed compared to other pitchers' sliders and has some two-plane movement. His cutter (take this with a grain of salt because he's only thrown 9 of them in 2018) is an extreme flyball pitch compared to other pitchers' cutters. His slow curve (take this with a grain of salt because he's only thrown 1 of them in 2018) is a real yakker that's separated from his other curveball due to its big drop and slow speed.
