Houston Astros

Pitch Repertoire At-A-Glance

Zack Greinke has thrown 39,088 pitches that have been tracked by the PITCHf/x system between 2008 and 2021, all of them occuring in the MLB Regular Season. In 2021, he has relied primarily on his Fourseam Fastball (89mph), Change (87mph) and Curve (72mph), also mixing in a Sinker (90mph) and Slider (83mph). He also rarely throws a Slow Curve (59mph) and Splitter (65mph).


In 2021, compared to other RHP:
His fourseam fastball comes in below hitting speed, is straight as an arrow, generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and results in somewhat more flyballs compared to other pitchers' fourseamers. His change dives down out of the zone and is slightly firmer than usual. His curve comes in below hitting speed, has a sharp downward bite and has slight glove-side movement. His sinker is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical and has slightly below average velo. His slider generates fewer whiffs/swing compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. His slow curve (take this with a grain of salt because he's only thrown 5 of them in 2021) is a real yakker that's separated from his other curveball due to its big drop and slow speed. His splitter (take this with a grain of salt because he's only thrown 1 of them in 2021) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters and has movement that suggests an extreme amount of backspin.
