Eric Lauer has thrown 4,830 pitches that have been tracked by the PITCHf/x system between 2018 and 2021, all of them occuring in the MLB Regular Season. In 2021, he has relied primarily on his Fourseam Fastball (92mph), Slider (80mph) and Cutter (91mph), also mixing in a Change (86mph).
In 2021, compared to other LHP:
His fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. His 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 and has exceptional depth. His cutter is thrown at a speed that's borderline unfair, generates an extremely high number of swings & misses compared to other pitchers' cutters, has surprisingly little cutting action, has good "rise" and results in somewhat more flyballs compared to other pitchers' cutters. His change (take this with a grain of salt because he's only thrown 18 of them in 2021) is much firmer than usual and has some natural sink to it.
