Pittsburgh Pirates
Although they have not thrown an MLB pitch in 2024, Steven Wright threw 5,381 pitches that were tracked by the PITCHf/x system between 2013 and 2019, all of them occuring in the MLB Regular Season. In 2019, they relied primarily on their Knuckleball (75mph), also mixing in a Sinker (82mph). He also rarely threw a Fourseam Fastball (83mph).
In 2019, compared to other RHP:
Their knuckleball flutters and floats unpredictably toward the plate. Their sinker (take this with a grain of salt because they've only thrown 7 of them in 2019) is so slow that it is substantially gravitational, is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has less armside run than typical. Their fourseam fastball (take this with a grain of salt because they've only thrown 1 of them in 2019) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers and is an extreme flyball pitch compared to other pitchers' fourseamers.
