Miami Marlins
Although they have not thrown an MLB pitch in 2024, Jeff Locke threw 10,935 pitches that were tracked by the PITCHf/x system between 2011 and 2017, including pitches thrown in the MLB Regular Season and Spring Training. In 2017, they relied primarily on their Sinker (91mph), Change using a Circle Change grip (81mph) and Fourseam Fastball (91mph), also mixing in a Curve using a Knuckle Curve grip (78mph).
In 2017, compared to other LHP:
Their sinker is basically never swung at and missed compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers and has less armside run than typical. Their change using a circle change grip has surprising cut action and generates more whiffs/swing compared to other pitchers' changeups. Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is basically never swung at and missed compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their curve using a knuckle curve grip is an extreme flyball pitch compared to other pitchers' curves, generates fewer whiffs/swing compared to other pitchers' curves and is slightly harder than usual.
