Mason Black has thrown 7,030 pitches that have been tracked by the PITCHf/x system between 2023 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Slider (84mph), Fourseam Fastball (94mph) and Sinker (94mph), also mixing in a Curve (81mph) and Cutter (90mph). He also rarely throws a Change (88mph) and Splitter (86mph).
In 2026, compared to other RHP:
Their slider has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has short glove-side cut. Their fourseam fastball has some natural sinking action, has essentially average velo and has slight armside run. Their sinker generates more whiffs/swing compared to other pitchers' sinkers, has slight armside run, has slightly above average velo and has some natural sinking action. Their curve generates fewer whiffs/swing compared to other pitchers' curves, is slightly harder than usual, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. Their cutter is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters, has surprisingly little cutting action, has slightly above average velo and has some natural sink. Their change dives down out of the zone, is much firmer than usual and results in somewhat more flyballs compared to other pitchers' changeups. Their splitter (take this with a grain of salt because they've only thrown 3 of them in 2026) is an extreme flyball pitch compared to other pitchers' splitters and is slightly firmer than usual.
