Pitch Repertoire At-A-Glance

Lucas Sims has thrown 7,046 pitches that have been tracked by the PITCHf/x system between 2017 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (94mph) and Slider (85mph), also mixing in a Curve (82mph) and Change (88mph). He also rarely throws a Cutter (91mph) and Sinker (94mph).


In 2026, compared to other RHP:
Their fourseam fastball has essentially average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, sweeps across the zone and generates more whiffs/swing compared to other pitchers' sliders. Their curve is much harder than usual and results in somewhat more flyballs compared to other pitchers' curves. Their change dives down out of the zone, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their cutter (take this with a grain of salt because they've only thrown 9 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has slightly above average velo. Their sinker (take this with a grain of salt because they've only thrown 6 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 and has well above average velo.
