Seattle Mariners
Caleb Ferguson has thrown 6,271 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 (94mph), Cutter (88mph), Sinker (94mph) and Curve (80mph). He also rarely throws a Splitter (84mph) and Slider (80mph).
In 2025, compared to other LHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action, has well above average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their cutter has heavy sink, has extreme cut action and has well above average velo. Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, generates more whiffs/swing compared to other pitchers' sinkers, has well above average velo and has less armside run than typical. Their curve is much harder than usual, has a sharp downward bite and has slight glove-side movement. Their splitter (take this with a grain of salt because they've only thrown 6 of them in 2025) is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action and is an extreme flyball pitch compared to other pitchers' splitters. Their slider (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' sliders, sweeps across the zone, has exceptional depth and results in more flyballs compared to other pitchers' sliders.
