Oakland Athletics
Jeffrey Springs has thrown 6,539 pitches that have been tracked by the PITCHf/x system between 2016 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (90mph), Slider (83mph) and Change (80mph). He also rarely throws a Cutter (87mph).
In 2025, compared to other LHP:
Their fourseam fastball results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their slider generates fewer whiffs/swing compared to other pitchers' sliders and has short glove-side cut. Their change dives down out of the zone, generates a high number of swings & misses compared to other pitchers' changeups, results in somewhat more flyballs compared to other pitchers' changeups and has slightly below average velo. Their cutter (take this with a grain of salt because they've only thrown 7 of them in 2025) is basically never swung at and missed compared to other pitchers' cutters and is an extreme flyball pitch compared to other pitchers' cutters.
