Kieboom is the favorite to be the Nationals' starting third baseman, though he'll have to earn his opportunities, according to manager Dave Martinez, Mark Zuckerman of MASNSports.com reports. Kieboom came with plenty of promise as a prospect and is still just 23 years old, but he's yet to come close to delivering on that promise so far. In 44 games over the past two seasons, he's hitting just .181/.309/.232, a line that wouldn't play anywhere and certainly not at an important offensive position like third base. The Nationals hope his talent will finally shine through this time around, but they presumably want to get back to their winning ways following a poor showing in 2020 and won't have much patience with him if his struggles remain significant at the start of the upcoming season.
The Nationals placed Kieboom on the 10-day injured list Wednesday with a left wrist contusion, Jessica Camerato of MLB.com reports. Kieboom wasn't progressing as quickly as hoped after being struck in the hand by a 95 mile-per-hour Zack Wheeler sinker in Monday's game against the Phillies, prompting the Nationals to shutter him for the season. After a rough 11-game cameo with the big club in 2019, the 23-year-old showed slight improvement this season, but his .202/.344/.212 slash line over 122 plate appearances still left much to be desired. Kieboom will likely have to battle for an everyday role at third base in spring training rather than being handed the job outright.
Kieboom (hand) remains out of the lineup Wednesday against the Phillies. Kieboom is dealing with a bruised left hand after a hit-by-pitch forced him out of Monday's contest. He sat out both games of Tuesday's twin bill, and he'll remain sidelined for the series finale against the Phillies. Brock Holt will start at the hot corner Wednesday.
Kieboom (hand) remains on the bench for the second half of Tuesday's doubleheader against Philadelphia. A bruised hand following a hit-by-pitch forced Kieboom out of Monday's game, and he'll be on the bench for both of Tuesday's games. Brock Holt starts at the hot corner this time around.
Kieboom (hand) will not start the first game of Tuesday's doubleheader against the Phillies. Kieboom left Monday's contest after getting hit by a pitch in the hand, though X-rays revealed nothing worse than a bruise. Whether or not he's in contention for the nightcap is uncertain. Josh Harrison starts at third base in his absence.
