Non-MLB
Although they have not thrown an MLB pitch in 2026, Sean Nolin threw 1,666 pitches that were tracked by the PITCHf/x system between 2013 and 2025, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2025, they relied primarily on their Fourseam Fastball (89mph), also mixing in a Change (79mph), Curve (75mph) and Cutter (83mph).
In 2025, compared to other LHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has some natural sinking action and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 16 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups, has below average velo and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 16 of them in 2025) is basically never swung at and missed compared to other pitchers' curves, has sweeping glove-side movement, is an extreme flyball pitch compared to other pitchers' curves and has a sharp downward bite. Their cutter (take this with a grain of salt because they've only thrown 16 of them in 2025) comes in below hitting speed, has heavy sink, has extreme cut action and is an extreme flyball pitch compared to other pitchers' cutters.
