Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Lucas Luetge threw 4,983 pitches that were tracked by the PITCHf/x system between 2012 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Cutter (87mph) and Slider (77mph), also mixing in a Curve (73mph). He also rarely threw a Fourseam Fastball (88mph).
In 2023, compared to other LHP:
Their cutter has heavy sink and has sweeping cut action. Their slider comes in below hitting speed, sweeps across the zone, has exceptional depth and generates fewer whiffs/swing compared to other pitchers' sliders. Their curve has an exceptional bite, generates an extremely high number of swings & misses compared to other pitchers' curves, has below average velo, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 8 of them in 2023) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is straight as an arrow, is an extreme flyball pitch compared to other pitchers' fourseamers and has below average velo.
