Cincinnati Reds
Although they have not thrown an MLB pitch in 2024, Kevin Shackelford threw 693 pitches that were tracked by the PITCHf/x system between 2017 and 2018, including pitches thrown in the MLB Regular Season and Spring Training. In 2018, they relied primarily on their Cutter (93mph), Slider (87mph) and Sinker (94mph). He also rarely threw a Change (96mph).
In 2018, compared to other RHP:
Their cutter is thrown at a speed that's borderline unfair, generates fewer whiffs/swing compared to other pitchers' cutters, results in more flyballs compared to other pitchers' cutters, has good "rise" and has little cutting action. Their slider is much harder than usual and has some two-plane movement. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, has well above average velo, has less armside run than typical, has little sinking action compared to a true sinker and results in somewhat more flyballs compared to other pitchers' sinkers. Their change (take this with a grain of salt because they've only thrown 1 of them in 2018) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
