Chicago White Sox
Nick Nastrini has thrown 3,268 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (93mph), also mixing in a Slider (85mph), Curve (79mph) and Splitter (85mph). He also rarely throws a Change (85mph).
In 2025, compared to other RHP:
Their fourseam fastball is straight as an arrow and has essentially average velo. Their slider has some two-plane movement. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement and has a sharp downward bite. Their splitter generates an extremely high number of swings & misses compared to other pitchers' splitters, has surprising cut action, has some natural sink to it and results in somewhat more flyballs compared to other pitchers' splitters. Their change (take this with a grain of salt because they've only thrown 1 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
