Originally signed for $250,000 by the Yankees at the start of the 2016-17 international signing period, Contreras had a very strong year in Low-A in 2019 and was added to the team’s 40-man roster in Nov. 2020 as what appeared to be a high-floor type starting pitcher. Sent to the Pirates in Jan. 2021 as part of the Jameson Taillon trade, Contreras saw his stuff -- and his stock -- skyrocket, despite missing a large chunk of time with a forearm strain. He capped things off with a strong big league debut and a turn as one of the better pitching prospects in the Arizona Fall League.
Contreras has seen his fastball go from a solid offering to an explosive one that touched 97-98 mph with ease and averaged around 96 mph with excellent life and high spin rates in 2021. He has both a high-spin 80-mph curve and a mid-80s slider, showing the ability to miss bats with both of them on a regular basis. While he doesn’t use it as much, his changeup features good sink and should be a legitimate above-average fourth offering.
The right-hander finds the strike zone consistently with all of his pitches, and he’s very athletic on the mound, so he could have better-than-average command eventually. There are concerns about health and durability, especially given the injury in 2021, but the Pirates were erring on the side of caution, and Contreras is strong even though he’s undersized, giving confidence he’ll be able to hold up as a big league starter.
