Although they have not thrown an MLB pitch in 2024, Kirby Yates threw 6,378 pitches that were tracked by the PITCHf/x system between 2014 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Fourseam Fastball (94mph) and Splitter (86mph). He also rarely threw a Slider (78mph).
In 2023, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has an obvious tail, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their splitter has dives down out of the zone, is slightly firmer than usual and has slight armside fade. Their slider (take this with a grain of salt because they've only thrown 17 of them in 2023) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders.
