Garrett Whitlock has thrown 5,173 pitches that have been tracked by the PITCHf/x system between 2021 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (96mph), Slider (84mph) and Change (85mph). He also rarely throws a Cutter (89mph).
In 2025, compared to other RHP:
Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is blazing fast, results in more flyballs compared to other pitchers' sinkers and has little sinking action compared to a true sinker. Their slider has exceptional depth. Their change has an obvious armside fade and dives down out of the zone. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2025) 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 little cutting action.
