Seattle Mariners
Austin Kitchen has thrown 1,167 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 Sinker (91mph) and Slider (79mph), also mixing in a Change (84mph) and Curve (73mph).
In 2025, compared to other LHP:
Their sinker has heavy sinking action and is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers. Their slider sweeps across the zone, has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders and has below average velo. Their change dives down out of the zone, generates a high number of swings & misses compared to other pitchers' changeups, results in many more groundballs compared to other pitchers' changeups and is slightly firmer than usual. Their curve (take this with a grain of salt because they've only thrown 18 of them in 2025) has sweeping glove-side movement, generates fewer whiffs/swing compared to other pitchers' curves, results in somewhat more flyballs compared to other pitchers' curves and has slightly below average velo.
