Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Bobby Jenks threw 3,358 pitches that were tracked by the PITCHf/x system between 2007 and 2011, including pitches thrown in the MLB Regular Season and Spring Training. In 2011, they relied primarily on their Fourseam Fastball (95mph) and Slider (87mph), also mixing in a Change (85mph). He also rarely threw a Sinker (93mph) and Curve using a Knuckle Curve grip (83mph).
In 2011, compared to other RHP:
Their fourseam fastball has some natural sinking action, results in somewhat more groundballs compared to other pitchers' fourseamers, has slightly above average velo and has slightly less natural movement than typical. Their slider is an extreme flyball pitch compared to other pitchers' sliders, is much harder than usual and has some two-plane movement. Their change dives down out of the zone and results in somewhat more flyballs compared to other pitchers' changeups. Their sinker (take this with a grain of salt because they've only thrown 12 of them in 2011) is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run, generates more whiffs/swing compared to other pitchers' sinkers, has slightly above average velo and has some natural sinking action. Their curve using a knuckle curve grip (take this with a grain of salt because they've only thrown 12 of them in 2011) has an exceptional bite, generates an extremely high number of swings & misses compared to other pitchers' curves, is much harder than usual and results in more flyballs compared to other pitchers' curves.
