Lance McCullers Jr. has thrown 9,968 pitches that have been tracked by the PITCHf/x system between 2015 and 2021, all of them occuring in the MLB Regular Season. In 2021, he has relied primarily on his Sinker (94mph) and Slider (86mph), also mixing in a Curve (84mph) and Change (86mph). He also rarely throws a Cutter (89mph) and Fourseam Fastball (94mph).
In 2021, compared to other RHP:
His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, results in somewhat more groundballs compared to other pitchers' sinkers, has slightly above average velo and has some natural sinking action. His slider sweeps across the zone. His curve is thrown extremely hard and has a sharp downward bite. His change has an obvious armside fade, dives down out of the zone, results in many more groundballs compared to other pitchers' changeups and is slightly firmer than usual. His cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink, is an extreme flyball pitch compared to other pitchers' cutters and has strong cutting action. His fourseam fastball (take this with a grain of salt because he's only thrown 6 of them in 2021) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical.
