Seattle Mariners
Jordan Holloway has thrown 1,754 pitches that have been tracked by the PITCHf/x system between 2020 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (87mph) and Fourseam Fastball (98mph), also mixing in a Sinker (97mph). He also rarely throws a Curve (79mph).
In 2024, compared to other RHP:
Their slider has exceptional depth and is much harder than usual. 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, generates more whiffs/swing compared to other pitchers' fourseamers and has less armside movement than typical. Their sinker 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 less armside run than typical. Their curve (take this with a grain of salt because they've only thrown 7 of them in 2024) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite and has slight glove-side movement.
