Non-MLB
Although they have not thrown an MLB pitch in 2024, Joe Biagini threw 5,698 pitches that were tracked by the PITCHf/x system between 2016 and 2023, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2023, they relied primarily on their Cutter (85mph) and Fourseam Fastball (92mph), also mixing in a Sinker (92mph) and Change (82mph).
In 2023, compared to other RHP:
Their cutter (take this with a grain of salt because they've only thrown 4 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has below average velo, has some natural sink and has strong cutting action. Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2023) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical and has essentially average velo. Their sinker (take this with a grain of salt because they've only thrown 2 of them in 2023) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has virtually no sinking action reminiscent of a true sinker. Their change (take this with a grain of salt because they've only thrown 1 of them in 2023) 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 slightly below average velo.
