Although they have not thrown an MLB pitch in 2024, Ronald Herrera threw 45 pitches that were tracked by the PITCHf/x system in 2017, all of them occuring in the MLB Regular Season. In 2017, they relied primarily on their Change (85mph) and Fourseam Fastball (92mph), also mixing in a Slider (86mph), Sinker (92mph) and Curve (79mph).
In 2017, compared to other RHP:
Their change (take this with a grain of salt because they've only thrown 17 of them in 2017) generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their fourseam fastball (take this with a grain of salt because they've only thrown 14 of them in 2017) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their slider (take this with a grain of salt because they've only thrown 8 of them in 2017) is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has less than expected depth and has primarily 12-6 movement. Their sinker (take this with a grain of salt because they've only thrown 3 of them in 2017) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 3 of them in 2017) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has primarily 12-6 movement.
