Charlie Beilenson has thrown 360 pitches that have been tracked by the PITCHf/x system between 2023 and 2026, including pitches thrown in The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Cutter (89mph), Fourseam Fastball (93mph) and Change (86mph), also mixing in a Slider (80mph) and Sinker (93mph).
In 2026, compared to other RHP:
Their cutter (take this with a grain of salt because they've only thrown 12 of them in 2026) has heavy sink, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has strong cutting action. Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2026) 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, has some natural sinking action and has essentially average velo. Their change (take this with a grain of salt because they've only thrown 10 of them in 2026) has surprising cut action, dives down out of the zone, generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and is slightly firmer than usual. Their slider (take this with a grain of salt because they've only thrown 9 of them in 2026) comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders. Their sinker (take this with a grain of salt because they've only thrown 5 of them in 2026) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has slightly above average velo.
