Nationals Call Up Carter Kieboom

Carter Kieboom is on his way to join the Nationals in Baltimore, per Jesse Dougherty of the Washington Post, who first suggested (via Twitter) that he’d be added to the roster in place of Jordy Mercer. As expected, the Nationals announced the move, with Mercer landing back on the 10-day injured list with a left calf strain, retroactive to July 21st, and Kieboom on his way to the Major League roster.

Regardless of the cause, it’s an interesting time for the Nationals to make a move with Kieboom, once a top prospect in baseball and still one of Washington’s top trade chips. With less than a week before the trade deadline, there’s not much time for a showcase of any kind, whether it be for the Nats to show him off to other clubs, or even just to get a look at him themselves.

It’s looking less and less like the Nationals are readying to make a push for contention, so perhaps this is just the beginning of a season-long showcase for Kieboom to prove himself at the hot corner. He’s had opportunity before, but never on ideal terms. He was rushed to the Majors in 2019 because of a Trea Turner injury, then took over for departed franchise icon Anthony Rendon for a shortened season during a global pandemic. Though he hasn’t performed as expected in the Majors, the book is hardly closed on Kieboom.
