Los Angeles Dodgers
Will Klein has thrown 2,868 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (98mph), also mixing in a Cutter (92mph), Curve (86mph) and Slider (88mph). He also rarely throws a Sinker (98mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, generates a very high amount of groundballs compared to other pitchers' fourseamers and is blazing fast. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink and has well above average velo. Their curve is thrown extremely hard, generates more whiffs/swing compared to other pitchers' curves, has a sharp downward bite and has primarily 12-6 movement. Their slider has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and is much harder than usual. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has little sinking action compared to a true sinker.
