Seattle Mariners
Although they have not thrown an MLB pitch in 2026, Josh Fleming threw 7,000 pitches that were 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 relied primarily on their Sinker (89mph), Change (81mph) and Cutter (86mph), also mixing in a Slider (77mph). He also rarely threw a Fourseam Fastball (87mph).
In 2025, compared to other LHP:
Their sinker has heavy sinking action and is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers. Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone and generates fewer whiffs/swing compared to other pitchers' changeups. Their cutter generates fewer whiffs/swing compared to other pitchers' cutters, results in somewhat more flyballs compared to other pitchers' cutters and has some natural sink. Their slider comes in below hitting speed, sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 1 of them in 2025) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers and is an extreme flyball pitch compared to other pitchers' fourseamers.
