2023 Fantasy Outlook
The Nationals planned on having Kieboom compete for the starting job at third base, but he was first diagnosed with a flexor mass strain before learning he also had a sprained UCL. After attempting to rehab, Kieboom had Tommy John surgery in May, with an expected recovery in advance of spring training. With the late season emergence of Joey Meneses and the acquisition of Jeimer Candelario, Kieboom's clearest path to playing time could be designated hitter, which may not be a bad thing, at least early. Whether he earns the job is the question. Kieboom's MLB OPS is just .589, and he's been off for a year. He's worth tracking in the spring, but pre-injury, Kieboom demonstrated limited ability to handle major league pitching. Read Past Outlooks

Undergoes Tommy John surgery
Kieboom underwent Tommy John surgery Friday, Jessica Camerato of MLB.com reports.
ANALYSIS
Tommy John surgery doesn't come with as long of a recovery timeline for hitters as it does for pitchers, but Kieboom will still miss the remainder of his 2022 campaign. The Nationals hope he'll be ready for spring training next year, at which point he'll be coming off a lost season with a career .197/.304/.285 slash line to his name, though he'll still be just 25 years old.

Kieboom's prospect status continues to fade. The 24-year-old was once viewed as Anthony Rendon's heir apparent at the hot corner for Washington, but over the last three seasons he's stumbled to a .589 OPS over 414 plate appearances in the majors with a 26.8 percent strikeout rate. Kieboom's struggles as a hitter have followed him into the field and also accompanied him down to Triple-A Rochester in 2021, and the Nationals have cycled through a number of veteran stopgaps while waiting for things to finally click for the 2016 first-round pick. That wait will be even longer after Kieboom was diagnosed with a sprained UCL in his elbow and a flexor mass strain in his forearm this spring, putting the possibility of Tommy John surgery that would likely cost him the entire campaign on the table. Even if he does avoid surgery and is able to get back on the field over the summer, Kieboom has a lot to prove before he'll be able to take over at third base on the big-league roster.
