Toronto Blue Jays
Although they have not thrown an MLB pitch in 2024, Ryan Feierabend threw 1,866 pitches that were tracked by the PITCHf/x system between 2007 and 2019, including pitches thrown in the MLB Regular Season and Spring Training. In 2019, they relied primarily on their Knuckleball (75mph) and Fourseam Fastball (86mph), also mixing in a Change (77mph). He also rarely threw a Curve (72mph).
In 2019, compared to other LHP:
Their knuckleball flutters and floats unpredictably toward the plate. Their fourseam fastball comes in below hitting speed. Their change (take this with a grain of salt because they've only thrown 7 of them in 2019) comes in below hitting speed and is an extreme flyball pitch compared to other pitchers' changeups. Their curve (take this with a grain of salt because they've only thrown 2 of them in 2019) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has below average velo and has slight glove-side movement.
