Non-MLB
Humberto Mejía has thrown 1,558 pitches that have been tracked by the PITCHf/x system between 2020 and 2026, including pitches thrown in the MLB Regular Season and The World Baseball Classic. In 2026, they have relied primarily on their Cutter (90mph), also mixing in a Fourseam Fastball (92mph), Sinker (91mph) and Curve (77mph).
In 2026, compared to other RHP:
Their cutter (take this with a grain of salt because they've only thrown 7 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has slightly above average velo. Their fourseam fastball (take this with a grain of salt because they've only thrown 2 of them in 2026) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slightly less natural movement than typical. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2026) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has surprisingly little armside run. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2026) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has a sharp downward bite.
