Chicago Cubs
Although they have not thrown an MLB pitch in 2024, Ethan Roberts threw 177 pitches that were tracked by the PITCHf/x system in 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (94mph) and Slider (83mph), also mixing in a Curve (81mph).
In 2022, compared to other RHP:
Their fourseam fastball has heavy sinking action, is straight as an arrow, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone and has exceptional depth. Their curve (take this with a grain of salt because they've only thrown 11 of them in 2022) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite, is slightly harder than usual and has slight glove-side movement.
