Chicago Cubs
Ethan Roberts has thrown 2,023 pitches that have been tracked by the PITCHf/x system between 2022 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Slider (84mph) and Cutter (93mph), also mixing in a Sinker (94mph).
In 2026, compared to other RHP:
Their slider sweeps across the zone and has some two-plane movement. Their cutter is thrown at a speed that's borderline unfair, generates a very high amount of groundballs compared to other pitchers' cutters, has good "rise" and has little cutting action. Their sinker generates a high number of swings & misses compared to other pitchers' sinkers, has well above average velo, has less armside run than typical, results in somewhat more flyballs compared to other pitchers' sinkers and has some natural sinking action.
