Non-MLB
Although they have not thrown an MLB pitch in 2024, Carlos Contreras threw 1,027 pitches that were tracked by the PITCHf/x system between 2013 and 2023, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2023, they relied primarily on their Fourseam Fastball (93mph), Sinker (92mph) and Curve (81mph), also mixing in a Change (86mph).
In 2023, compared to other RHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slight armside run. Their sinker results in somewhat more flyballs compared to other pitchers' sinkers. Their curve has primarily 12-6 movement, generates more whiffs/swing compared to other pitchers' curves and is slightly harder than usual. Their change (take this with a grain of salt because they've only thrown 11 of them in 2023) results in more flyballs compared to other pitchers' changeups, is slightly firmer than usual, has slight armside fade and has some natural sink to it.
