Non-MLB
Although they have not thrown an MLB pitch in 2024, Erick Aybar threw 13 pitches that were tracked by the PITCHf/x system in 2017, all of them occuring in the MLB Regular Season. In 2017, they relied primarily on their Fourseam Fastball (72mph) and Knuckleball (65mph).
In 2017, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 9 of them in 2017) comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action and has less armside movement than typical. Their knuckleball (take this with a grain of salt because they've only thrown 4 of them in 2017) flutters and floats unpredictably toward the plate.
