Seattle Mariners
Jhonathan Diaz has thrown 3,278 pitches that have been tracked by the PITCHf/x system between 2021 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (79mph) and Sinker (88mph), also mixing in a Curve (74mph) and Change (81mph). He also rarely throws a Fourseam Fastball (90mph).
In 2024, compared to other LHP:
Their slider sweeps across the zone, generates more whiffs/swing compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their sinker has heavy sinking action, has less armside run than typical and has slightly below average velo. Their curve generates fewer whiffs/swing compared to other pitchers' curves, has a sharp downward bite, has slight glove-side movement and has slightly below average velo. Their change dives down out of the zone and results in more flyballs compared to other pitchers' changeups. Their fourseam fastball (take this with a grain of salt because they've only thrown 17 of them in 2024) has heavy sinking action, is an extreme flyball pitch compared to other pitchers' fourseamers and has essentially average velo.
