Arizona Diamondbacks
Although they have not thrown an MLB pitch in 2024, Matt Marksberry threw 485 pitches that were tracked by the PITCHf/x system between 2015 and 2019, including pitches thrown in the MLB Regular Season and Spring Training. In 2019, they relied primarily on their Fourseam Fastball (88mph) and Curve (75mph).
In 2019, compared to other LHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2019) is basically never swung at and missed compared to other pitchers' fourseamers, is straight as an arrow, is an extreme flyball pitch compared to other pitchers' fourseamers, has below average velo and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 7 of them in 2019) generates an extremely high number of swings & misses compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has a sharp downward bite.
