Los Angeles Angels
Jack Kochanowicz has thrown 1,281 pitches that have been tracked by the PITCHf/x system between 2024 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (96mph), Slider (87mph) and Fourseam Fastball (96mph). He also rarely throws a Curve (84mph).
In 2025, compared to other RHP:
Their sinker has heavy sinking action, is blazing fast and generates fewer whiffs/swing compared to other pitchers' sinkers. Their slider results in many more groundballs compared to other pitchers' sliders, is much harder than usual and has some two-plane movement. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has well above average velo. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2025) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' curves and results in more flyballs compared to other pitchers' curves.
