Seattle Mariners
Michael Rucker has thrown 2,981 pitches that have been tracked by the PITCHf/x system between 2021 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (96mph) and Curve (82mph), also mixing in a Sinker (96mph).
In 2026, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action and has well above average velo. Their curve (take this with a grain of salt because they've only thrown 4 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' curves, has sweeping glove-side movement, is much harder than usual and results in more flyballs compared to other pitchers' curves. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2026) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, is blazing fast, has slight armside run and has some natural sinking action.
