Pittsburgh Pirates
Although they have not thrown an MLB pitch in 2024, Hayden Penn threw 560 pitches that were tracked by the PITCHf/x system between 2009 and 2010, including pitches thrown in the MLB Regular Season and Spring Training. In 2010, they relied primarily on their Fourseam Fastball (94mph), Sinker (94mph) and Curve (79mph).
In 2010, compared to other RHP:
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 slightly above average velo and has slightly less natural movement than typical. Their sinker is an extreme flyball pitch compared to other pitchers' sinkers, generates fewer whiffs/swing compared to other pitchers' sinkers, has well above average velo, has less armside run than typical and has some natural sinking action. Their curve has an exceptional bite and is basically never swung at and missed compared to other pitchers' curves.
