Boston Red Sox
Reidis Sena has thrown 283 pitches that have been tracked by the PITCHf/x system between 2025 and 2026, including pitches thrown in The World Baseball Classic, Spring Training and Fall/Winter Ball. In 2026, they have relied primarily on their Slider (89mph) and Fourseam Fastball (96mph), also mixing in a Curve (85mph). He also rarely throws a Change (89mph).
In 2026, compared to other RHP:
Their slider is thrown extremely hard, has primarily 12-6 movement, generates fewer whiffs/swing compared to other pitchers' sliders and results in more flyballs compared to other pitchers' sliders. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers and has well above average velo. Their curve is thrown extremely hard, generates a high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement, has a sharp downward bite and results in somewhat more flyballs compared to other pitchers' curves. Their change (take this with a grain of salt because they've only thrown 8 of them in 2026) is thrown extremely hard, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
