Oakland Athletics
Although they have not thrown an MLB pitch in 2024, Anthony Kay threw 2,690 pitches that were tracked by the PITCHf/x system between 2019 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Slider (85mph) and Fourseam Fastball (95mph), also mixing in a Change (88mph).
In 2023, compared to other LHP:
Their slider (take this with a grain of salt because they've only thrown 9 of them in 2023) sweeps across the zone, results in more flyballs compared to other pitchers' sliders, is much harder than usual and has some two-plane movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 6 of them in 2023) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, is blazing fast, has less armside movement than typical and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 1 of them in 2023) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and has some natural sink to it.
