Nationals infielder Carter Kieboom will miss the entire 2022 season after undergoing Tommy John surgery, manager Dave Martinez told reporters (including Jesse Dougherty of the Washington Post). The 24-year-old has been on the IL since Spring Training because of a UCL strain in his throwing elbow.
It’ll be a lost critical development year for Kieboom. A former first-round pick, the righty-hitting infielder later developed into one of the sport’s top prospects. He reached the big leagues late in 2019, his age-21 season. The following winter, Baseball America ranked the Georgia native as the most promising player in the Washington farm system and named him the #15 prospect league-wide. The hope was that he’d cement himself as the third baseman of the future after Anthony Rendon departed in free agency, but he’s not yet staked a claim to that job.
More to come.
