Non-MLB
Although they have not thrown an MLB pitch in 2026, Alex Speas threw 1,854 pitches that were tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they relied primarily on their Slider (90mph), Fourseam Fastball (99mph) and Cutter (95mph). He also rarely threw a Sinker (97mph).
In 2025, compared to other RHP:
Their slider is thrown extremely hard and has some two-plane movement. Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair and has some natural sinking action. Their cutter is thrown at a speed that's borderline unfair, generates a high number of swings & misses compared to other pitchers' cutters, generates a very high amount of groundballs compared to other pitchers' cutters, has little cutting action and has some natural sink. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers and has some natural sinking action.
