Seattle Mariners
Gabe Speier has thrown 2,339 pitches that have been tracked by the PITCHf/x system between 2018 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (96mph), Slider (82mph) and Sinker (95mph). He also rarely throws a Change (90mph).
In 2025, compared to other LHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is blazing fast, results in more flyballs compared to other pitchers' fourseamers and has some natural sinking action. Their slider has exceptional depth, has short glove-side cut and results in somewhat more flyballs compared to other pitchers' sliders. Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, is blazing fast and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 1 of them in 2025) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone, is an extreme flyball pitch compared to other pitchers' changeups and has slight cut action.
