Arizona Diamondbacks
Kyle Nelson has thrown 2,547 pitches that have been tracked by the PITCHf/x system between 2020 and 2025, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2025, they have relied primarily on their Slider (83mph) and Fourseam Fastball (88mph). He also rarely throws a Cutter (86mph).
In 2025, compared to other LHP:
Their slider is a prototypical pitch with few remarkable qualities. Their fourseam fastball has much less armside movement than typical, has below average velo, has some natural sinking action and results in somewhat more flyballs compared to other pitchers' fourseamers. Their cutter (take this with a grain of salt because they've only thrown 2 of them in 2025) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has strong cutting action.
