Alexy threw 2,408 pitches that were tracked by the PITCHf/x system between 2021 and 2022, including pitches thrown in the MLB Regular Season and Spring Training.

In 2022, compared to other RHP:
His fourseam fastball has slightly above average velo and has slightly less natural movement than typical. His slider has some two-plane movement. His curve has an exceptional bite and has primarily 12-6 movement. His change has surprising cut action, is much firmer than usual, has a lot of backspin and results in somewhat more flyballs compared to other pitchers' changeups.
