Non-MLB
Although they have not thrown an MLB pitch in 2024, Greg Mahle threw 335 pitches that were tracked by the PITCHf/x system between 2016 and 2018, including pitches thrown in the MLB Regular Season and Spring Training. In 2018, they relied primarily on their Fourseam Fastball (91mph) and Slider (85mph).
In 2018, compared to other LHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2018) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2018) is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has less than expected depth and has primarily 12-6 movement.
