San Diego Padres
Ron Marinaccio has thrown 3,766 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (94mph) and Change (82mph), also mixing in a Slider (82mph). He also rarely throws a Cutter (89mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slight armside run. Their change dives down out of the zone, results in somewhat more flyballs compared to other pitchers' changeups, has slight armside fade and has slightly below average velo. Their slider is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has short glove-side cut. Their cutter (take this with a grain of salt because they've only thrown 8 of them in 2025) has heavy sink and is an extreme flyball pitch compared to other pitchers' cutters.
