In 2014, they relied primarily on their Sinker (91mph) and Slider (81mph), also mixing in a Change (82mph) and Fourseam Fastball (93mph).
In 2014, compared to other RHP:
Their sinker (take this with a grain of salt because they've only thrown 19 of them in 2014) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their slider (take this with a grain of salt because they've only thrown 19 of them in 2014) has exceptional depth, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has below average velo. Their change (take this with a grain of salt because they've only thrown 10 of them in 2014) generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has slightly below average velo. Their fourseam fastball (take this with a grain of salt because they've only thrown 8 of them in 2014) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has essentially average velo.
