Seattle Mariners
Gabe Speier has thrown 3,377 pitches that have been tracked by the PITCHf/x system between 2018 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Slider (84mph), Fourseam Fastball (95mph) and Sinker (95mph). He also rarely throws a Change (90mph).
In 2026, compared to other LHP:
Their slider has exceptional depth and results in somewhat more groundballs compared to other pitchers' sliders. 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, has some natural sinking action and has slightly less natural movement than typical. Their sinker generates an extremely high number of swings & misses 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 2 of them in 2026) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups.
