Non-MLB
Although they have not thrown an MLB pitch in 2024, Jason Gurka threw 347 pitches that were tracked by the PITCHf/x system between 2015 and 2017, including pitches thrown in the MLB Regular Season and Spring Training. In 2017, they relied primarily on their Curve (78mph) and Fourseam Fastball (91mph), also mixing in a Sinker (92mph).
In 2017, compared to other LHP:
Their curve (take this with a grain of salt because they've only thrown 12 of them in 2017) is an extreme flyball pitch compared to other pitchers' curves, generates more whiffs/swing compared to other pitchers' curves, is slightly harder than usual and has slight glove-side movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2017) 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 and has essentially average velo. Their sinker (take this with a grain of salt because they've only thrown 2 of them in 2017) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has slightly above average velo.
