Nationals pitching prospect Mason Denaburg recently underwent Tommy John surgery, reports Mark Zuckerman of MASNsports.com (Twitter link). The right-hander was Washington’s first-round pick out of a Florida high school in 2018.
This is the latest injury in a career that has been riddled with health problems so far. Seen as one of the most talented pitchers in the 2018 draft class, Denaburg fell to the Nationals at 27th overall due to biceps tendinitis. He didn’t pitch professionally that season, threw 20.1 innings of rookie ball in 2019, then missed all of last year recovering from shoulder surgery. He’ll now miss all of 2021 and quite likely a good portion of 2022 rehabbing from this latest procedure.
Denaburg remains a highly-regarded talent; Baseball America placed him ninth among Washington farmhands in their most recent organizational rankings. The 21-year-old will rehab and hopefully return to action at some point next season. Denaburg will be eligible for the Rule 5 draft if he’s not added to the Nationals’ 40-man roster after the 2022 season.
