Atlanta Braves
Hayden Harris has thrown 1,326 pitches that have been tracked by the PITCHf/x system between 2024 and 2026, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2026, they have relied primarily on their Fourseam Fastball (92mph) and Slider (82mph). He also rarely throws a Splitter (87mph) and Cutter (89mph).
In 2026, compared to other LHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action and has essentially average velo. Their slider sweeps across the zone, generates more whiffs/swing compared to other pitchers' sliders and results in more flyballs compared to other pitchers' sliders. Their splitter (take this with a grain of salt because they've only thrown 6 of them in 2026) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters, has some natural sink to it and has slight armside fade. Their cutter (take this with a grain of salt because they've only thrown 4 of them in 2026) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has well above average velo and has some natural sink.
