New York Mets
Although they have not thrown an MLB pitch in 2024, Justin Hampson threw 1,222 pitches that were tracked by the PITCHf/x system between 2007 and 2012, all of them occuring in the MLB Regular Season. In 2012, they relied primarily on their Slider (82mph) and Fourseam Fastball (86mph), also mixing in a Curve (75mph). He also rarely threw a Change (79mph).
In 2012, compared to other LHP:
Their slider generates fewer whiffs/swing compared to other pitchers' sliders. Their fourseam fastball comes in below hitting speed, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is basically never swung at and missed compared to other pitchers' fourseamers, has some natural sinking action and has slightly less natural movement than typical. Their curve is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has a sharp downward bite and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 5 of them in 2012) is basically never swung at and missed compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups and has slightly below average velo.
