Seattle Mariners
Caleb Ferguson has thrown 5,862 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).
In 2025, compared to other LHP:
Their fourseam fastball generates a very high amount of groundballs compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and has well above average velo. Their cutter has heavy sink, has extreme cut action and has slightly 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 and has well above average velo. 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.
