Charlie Beilenson has thrown 432 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 Fourseam Fastball (93mph) and Slider (81mph), also mixing in a Change (86mph), Cutter (89mph) and Sinker (93mph).
In 2026, compared to other RHP:
Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, has less armside movement than typical, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their slider sweeps across the zone, has exceptional depth, results in more flyballs compared to other pitchers' sliders and has below average velo. Their change has surprising cut action, dives down out of the zone, is slightly firmer than usual and results in somewhat more flyballs compared to other pitchers' changeups. Their cutter is an extreme flyball pitch compared to other pitchers' cutters, generates fewer whiffs/swing compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their sinker (take this with a grain of salt because they've only thrown 15 of them in 2026) is an extreme flyball pitch compared to other pitchers' sinkers and has some natural sinking action.
