Non-MLB
Although they have not thrown an MLB pitch in 2024, Brandon Cunniff threw 895 pitches that were tracked by the PITCHf/x system between 2015 and 2016, all of them occuring in the MLB Regular Season. In 2016, they relied primarily on their Fourseam Fastball (93mph), Slider (86mph) and Sinker (93mph), also mixing in a Change (82mph).
In 2016, compared to other RHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, generates more whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. Their slider has short glove-side cut, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. Their sinker generates a high number of swings & misses compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 18 of them in 2016) generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slightly below average velo and has some natural sink to it.
