Burdi has followed the path of his older brother Nick, going from closing games at Louisville to the early rounds of the Draft to Tommy John surgery. Nick (now with the Pirates) was a Twins second-rounder in 2014, while Zack signed for $2,128,500 as a White Sox first-rounder two years later and both needed elbow reconstruction in 2017. The younger Burdi returned at the end of last year to pitch 11 innings between Rookie ball and the Arizona Fall League, then made just 20 appearances in 2019 before needing surgery to repair a ligament tear in his patella.
Before Burdi got hurt, he averaged 12.9 strikeouts per nine innings thanks to a fastball that sat at 95-100 mph and peaked at 102 with some armside run and a low-90s slider with impressive depth. Chicago had him control his intensity during his initial return, when his heater parked at 92-96 mph and his slider operated in the mid-80s. A potential closer, he'll be under no restrictions in 2019.
Burdi hasn't used it much in pro ball but his tumbling changeup can be a plus pitch at its best, keeping hitters from sitting on his fastball, which can get straight on occasion. Once he's back at full strength, refining his control and command is all he needs to do to earn his first big league callup. He sometimes has trouble keeping his delivery in sync and loses direction to the plate.
