Gabe Speier has thrown 3,335 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).
In 2026, compared to other LHP:
Their slider has exceptional depth and generates a very high amount of 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, has some natural sinking action and has slightly less natural movement than typical. Their sinker (take this with a grain of salt because they've only thrown 19 of them in 2026) is blazing fast and has some natural sinking action.
