Pittsburgh Pirates
Although they have not thrown an MLB pitch in 2023, Rich Hill threw 18,362 pitches that were tracked by the PITCHf/x system between 2007 and 2022, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2022, they relied primarily on their Curve (72mph) and Fourseam Fastball (89mph), also mixing in a Cutter (84mph) and Slider (69mph). He also rarely threw a Sinker (84mph), Change (82mph) and Slow Curve (64mph).
In 2022, compared to other LHP:
His curve has an exceptional bite, has sweeping glove-side movement, has below average velo and generates fewer whiffs/swing compared to other pitchers' curves. His fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has below average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. His cutter results in somewhat more flyballs compared to other pitchers' cutters, has slightly below average velo, has some natural sink and has strong cutting action. His slider comes in below hitting speed, sweeps across the zone and has some two-plane movement. His sinker is so slow that it is substantially gravitational, has heavy sinking action and results in more flyballs compared to other pitchers' sinkers. His change is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. His slow curve (take this with a grain of salt because he's only thrown 4 of them in 2022) is a real yakker that's separated from his other curveball due to its big drop and slow speed.
