Toronto Blue Jays
Although they have not thrown an MLB pitch in 2023, Yusei Kikuchi threw 8,038 pitches that were tracked by the PITCHf/x system between 2019 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (95mph) and Slider (86mph), also mixing in a Change (87mph) and Cutter (91mph).
In 2022, compared to other LHP:
His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers and has well above average velo. His slider is much harder than usual and has some two-plane movement. His change is thrown extremely hard, has surprising cut action, generates more whiffs/swing compared to other pitchers' changeups, results in many more groundballs compared to other pitchers' changeups and has some natural sink to it. His cutter is thrown at a speed that's borderline unfair and has strong cutting action.
