Pitch Repertoire At-A-Glance

John King has thrown 4,939 pitches that have been tracked by the PITCHf/x system between 2020 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Slider (83mph) and Sinker (92mph), also mixing in a Change (83mph), Fourseam Fastball (92mph) and Curve (80mph).


In 2026, compared to other LHP:
Their slider sweeps across the zone, has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders and results in somewhat more flyballs compared to other pitchers' sliders. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, results in many more groundballs compared to other pitchers' sinkers, has less armside run than typical and has slightly above average velo. Their change generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups. Their fourseam fastball has heavy sinking action, has essentially average velo and has slightly less natural movement than typical. Their curve (take this with a grain of salt because they've only thrown 19 of them in 2026) generates fewer whiffs/swing compared to other pitchers' curves, is much harder than usual, has a sharp downward bite, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement.
