Ron Marinaccio has thrown 4,771 pitches that have been tracked by the PITCHf/x system between 2022 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (94mph) and Change (81mph), also mixing in a Cutter (86mph). He also rarely throws a Slider (82mph).
In 2026, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has an obvious tail, has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their change has an obvious armside fade, dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups, results in somewhat more flyballs compared to other pitchers' changeups and has slightly below average velo. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink, is an extreme flyball pitch compared to other pitchers' cutters, has below average velo and has strong cutting action. Their slider (take this with a grain of salt because they've only thrown 9 of them in 2026) sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders, has below average velo and has less than expected depth.
