Non-MLB
Although they have not thrown an MLB pitch in 2023, Shaun Anderson threw 2,481 pitches that were tracked by the PITCHf/x system between 2019 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Slider (85mph) and Fourseam Fastball (93mph), also mixing in a Change (86mph) and Sinker (93mph).
In 2022, compared to other RHP:
Their slider has short glove-side cut. Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, has much less armside movement than typical, results in more flyballs compared to other pitchers' fourseamers and has essentially average velo. Their change (take this with a grain of salt because they've only thrown 13 of them in 2022) dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups, is slightly firmer than usual and results in somewhat more flyballs compared to other pitchers' changeups. Their sinker (take this with a grain of salt because they've only thrown 9 of them in 2022) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has slight armside run.
