Devin Smeltzer has thrown 4,539 pitches that have been tracked by the PITCHf/x system between 2019 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (76mph), Sinker (87mph) and Change (82mph), also mixing in a Fourseam Fastball (89mph). He also rarely throws a Curve (75mph).
In 2024, compared to other LHP:
Their slider comes in below hitting speed, sweeps across the zone, results in more flyballs compared to other pitchers' sliders and has some two-plane movement. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, has below average velo, results in more flyballs compared to other pitchers' sinkers and has less armside run than typical. Their change has surprising cut action, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups. Their fourseam fastball (take this with a grain of salt because they've only thrown 12 of them in 2024) has below average velo, results in more flyballs compared to other pitchers' fourseamers and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 6 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' curves, has sweeping glove-side movement, is an extreme flyball pitch compared to other pitchers' curves, has a sharp downward bite and has slightly below average velo.
