Pittsburgh Pirates
Andrew Heaney has thrown 17,771 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 Cutter (85mph).
In 2025, compared to other LHP:
Their fourseam fastball has heavy sinking action, has essentially average velo, results in somewhat more groundballs compared to other pitchers' fourseamers and has slight armside run. Their slider is basically never swung at and missed compared to other pitchers' sliders and has exceptional depth. Their change dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups, results in many more groundballs compared to other pitchers' changeups and has slight armside fade. 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.
