Pittsburgh Pirates
Although they have not thrown an MLB pitch in 2024, A.J. Burnett threw 27,275 pitches that were tracked by the PITCHf/x system between 2007 and 2015, including pitches thrown in the MLB Regular Season and the MLB Postseason. In 2015, they relied primarily on their Sinker (91mph) and Curve using a Knuckle Curve grip (82mph), also mixing in a Fourseam Fastball (92mph) and Change (86mph).
In 2015, compared to other RHP:
Their sinker has less armside run than typical and has some natural sinking action. Their curve using a knuckle curve grip generates a very high amount of groundballs compared to other pitchers' curves, generates more whiffs/swing compared to other pitchers' curves, is much harder than usual and has primarily 12-6 movement. Their fourseam fastball has heavy sinking action and has essentially average velo. Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone and is slightly firmer than usual.
