Los Angeles Dodgers
Will Klein has thrown 2,954 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season, the MLB Postseason 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, is blazing fast and results in many more groundballs compared to other pitchers' fourseamers. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink, has well above average velo and results in somewhat more groundballs compared to other pitchers' cutters. Their curve is thrown extremely hard, has a sharp downward bite and has primarily 12-6 movement. Their slider has exceptional depth, 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.
