Kyle Muller has thrown 4,045 pitches that have been tracked by the PITCHf/x system between 2021 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (93mph) and Slider (86mph), also mixing in a Curve (80mph) and Change (88mph).
In 2024, compared to other LHP:
Their fourseam fastball is straight as an arrow, has some natural sinking action, results in somewhat more groundballs compared to other pitchers' fourseamers and has slightly above average velo. Their slider generates fewer whiffs/swing compared to other pitchers' sliders, is much harder than usual, has primarily 12-6 movement, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their curve is basically never swung at and missed compared to other pitchers' curves, is much harder than usual, has a sharp downward bite, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. Their change (take this with a grain of salt because they've only thrown 19 of them in 2024) is thrown extremely hard, generates a high number of swings & misses compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups and has some natural sink to it.
