Non-MLB
Although they have not thrown an MLB pitch in 2025, Alfredo Simon threw 12,932 pitches that were tracked by the PITCHf/x system between 2008 and 2024, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2024, they relied primarily on their Sinker using a Two-seam Fastball grip (90mph), also mixing in a Fourseam Fastball (91mph), Curve (76mph), Cutter (85mph) and Splitter (80mph).
In 2024, compared to other RHP:
Their sinker using a two-seam fastball grip (take this with a grain of salt because they've only thrown 18 of them in 2024) is an extreme flyball pitch compared to other pitchers' sinkers, generates fewer whiffs/swing compared to other pitchers' sinkers, has less armside run than typical and has slightly below average velo. Their fourseam fastball (take this with a grain of salt because they've only thrown 8 of them in 2024) is basically never swung at and missed compared to other pitchers' fourseamers, has slight armside run and has slightly below average velo. Their curve (take this with a grain of salt because they've only thrown 8 of them in 2024) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has slight glove-side movement and has slightly below average velo. Their cutter (take this with a grain of salt because they've only thrown 5 of them in 2024) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has below average velo and has some natural sink. Their splitter (take this with a grain of salt because they've only thrown 3 of them in 2024) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters and has movement that suggests a lot of backspin.
