Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Zach Putnam threw 2,551 pitches that were tracked by the PITCHf/x system between 2011 and 2017, including pitches thrown in the MLB Regular Season and Spring Training. In 2017, they relied primarily on their Splitter (84mph) and Fourseam Fastball (91mph), also mixing in a Cutter (91mph). He also rarely threw a Slider (90mph).
In 2017, compared to other RHP:
Their splitter generates a high number of swings & misses compared to other pitchers' splitters, has some natural sink to it and has slight armside fade. Their fourseam fastball 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, has slight armside run and has slightly below average velo. Their cutter (take this with a grain of salt because they've only thrown 14 of them in 2017) explodes on the hitter, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has well above average velo. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2017) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has much less depth than expected and has primarily 12-6 movement.
