Boston Red Sox
Garrett Whitlock has thrown 4,369 pitches that have been tracked by the PITCHf/x system between 2021 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (84mph), Change (85mph) and Sinker (94mph). He also rarely throws a Cutter (86mph).
In 2024, compared to other RHP:
Their slider is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth and results in somewhat more flyballs compared to other pitchers' sliders. Their change has an obvious armside fade and dives down out of the zone. Their sinker has an obvious tail, has slightly above average velo and has some natural sinking action. Their cutter (take this with a grain of salt because they've only thrown 5 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink, is an extreme flyball pitch compared to other pitchers' cutters and has below average velo.
