Texas Rangers
Although they have not thrown an MLB pitch in 2024, Jason Grilli threw 8,613 pitches that were tracked by the PITCHf/x system between 2007 and 2017, including pitches thrown in the MLB Regular Season and Spring Training. In 2017, they relied primarily on their Fourseam Fastball (93mph) and Slider (81mph). He also rarely threw a Change (86mph).
In 2017, compared to other RHP:
Their fourseam fastball has an obvious tail, generates a high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider sweeps across the zone, has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has below average velo. Their change (take this with a grain of salt because they've only thrown 6 of them in 2017) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, is slightly firmer than usual and has slight armside fade.
