Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2012) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch 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 2 of them in 2012) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has a lot of backspin. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2012) is basically never swung at and missed compared to other pitchers' sliders and is an extreme flyball pitch compared to other pitchers' sliders.
