Non-MLB
Although they have not thrown an MLB pitch in 2024, Ernesto Frieri threw 5,733 pitches that were tracked by the PITCHf/x system between 2009 and 2018, including pitches thrown in the MLB Regular Season and Spring Training. In 2018, they relied primarily on their Fourseam Fastball (91mph), Change (83mph) and Slider (83mph).
In 2018, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2018) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 4 of them in 2018) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their slider (take this with a grain of salt because they've only thrown 4 of them in 2018) is basically never swung at and missed compared to other pitchers' sliders and is an extreme flyball pitch compared to other pitchers' sliders.
