Colorado Rockies
Ryan Rolison has thrown 1,579 pitches that have been tracked by the PITCHf/x system between 2020 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (93mph) and Curve (79mph), also mixing in a Slider (85mph) and Change (87mph). He also rarely throws a Sinker (92mph).
In 2025, compared to other LHP:
Their fourseam fastball has heavy sinking action, is straight as an arrow, results in somewhat more groundballs compared to other pitchers' fourseamers and has slightly above average velo. Their curve has a sharp downward bite, is slightly harder than usual and has slight glove-side movement. Their slider has exceptional depth and is much harder than usual. Their change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, has surprising cut action and dives down out of the zone. Their sinker (take this with a grain of salt because they've only thrown 2 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run, has slightly above average velo and has some natural sinking action.
