Atlanta Braves
Although they have not thrown an MLB pitch in 2023, Tyler Matzek threw 4,857 pitches that were tracked by the PITCHf/x system between 2014 and 2022, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (94mph) and Slider (83mph). He also rarely threw a Cutter (87mph).
In 2022, compared to other LHP:
Their fourseam fastball has much less armside movement than typical, generates more whiffs/swing compared to other pitchers' fourseamers, has well above average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders and has short glove-side cut. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2022) has heavy sink, is basically never swung at and missed compared to other pitchers' cutters, has sweeping cut action, is an extreme flyball pitch compared to other pitchers' cutters and has slightly above average velo.
