Pitch Repertoire At-A-Glance

Janson Junk has thrown 7,176 pitches that have been tracked by the PITCHf/x system between 2021 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Slider (85mph) and Fourseam Fastball (94mph), also mixing in a Curve (82mph) and Change (88mph).


In 2025, compared to other RHP:
Their slider has short glove-side cut. Their fourseam fastball has much less armside movement than typical and has essentially average velo. Their curve generates fewer whiffs/swing compared to other pitchers' curves, is much harder than usual, has a sharp downward bite, has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' curves. Their change is thrown extremely hard, generates fewer whiffs/swing compared to other pitchers' changeups, results in many more groundballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it.
