Andrew Heaney has thrown 18,193 pitches that have been tracked by the PITCHf/x system between 2014 and 2025, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (90mph) and Slider (80mph), also mixing in a Change (83mph) and Sinker (90mph). He also rarely throws a Curve (73mph) and Cutter (85mph).
In 2025, compared to other LHP:
Their fourseam fastball has heavy sinking action, has an obvious tail and has essentially average velo. Their slider has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders, results in many more groundballs compared to other pitchers' sliders and has short glove-side cut. Their change dives down out of the zone, results in somewhat more flyballs compared to other pitchers' changeups and has slight armside fade. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, has an obvious tail and results in somewhat more flyballs compared to other pitchers' sinkers. Their curve has sweeping glove-side movement, has below average velo, generates more whiffs/swing compared to other pitchers' curves, has a sharp downward bite and results in somewhat more flyballs compared to other pitchers' curves. Their cutter (take this with a grain of salt because they've only thrown 10 of them in 2025) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has some natural sink.
