2019 Fantasy Outlook
Kieboom was an elite hitter at Low-A and High-A, and while he remains a good prospect, his stock has leveled off since a promotion to Double-A. He struggled to hit for power in the Eastern League, notching a .133 ISO in 62 games. That trend continued in the Arizona Fall League, where he hit .295/.427/.372 -- leading all hitters in walks (17) while tallying just three extra-base hits in 78 at-bats. He won't need to be a middle-of-the-order bat to play every day, but the expectation a year ago was that he would be at least a 20-homer threat in the majors. It now seems a little less likely that Kieboom hits for impactful power while also hitting around .280. Perhaps he ends up hitting .265 with 25 homers, which is still valuable production from an infielder. If Anthony Rendon leaves in free agency after the 2019 season, Kieboom will serve as his long-term replacement at third base. That said, if Kieboom looks ready this summer, he may debut at the keystone. Read Past Outlooks

March 18, 2019
Kieboom went 2-for-4 with two singles and two strikeouts in Monday's action against the Mets.
Kieboom continues to make the most of his opportunity in spring training, as he is now 11-for-35 with six extra-base hits. He has also shown decent control of the strike zone, walking five times and striking out seven. He peaked at Double-A Harrisburg in 2018, so the chances of Kieboom breaking camp with the club are minuscule, but he has done nothing to hurt his future chances with his strong performance.

Past Fantasy Outlooks
In an injury shortened campaign, Kieboom still impressed enough in his first year in a full season league to generate Troy Tulowitzki comps. Prior to a mid May hamstring injury that cost him 10 weeks, he slashed .333/.398/.586 with six home runs and a 25:10 K:BB in 123 plate appearances. While Kieboom was quite a bit worse (.755 OPS) after returning to Hagerstown in mid August, he still got on base a ton (.402 OBP, 18 walks in 19 games), and looks more than ready for an assignment to High-A. Thanks to impressive bat speed and a very advanced approach, the 6-foot-2 shortstop has the foundation to hit for average and for power, potentially flirting with some .300/.400/.500 seasons. He is a below-average runner, so his bat will have to provide all of his fantasy value. His defense at shortstop is passable, but not good enough to displace a quality option, so it’s possible his future home is second base or third base.
The 28th overall pick in the 2016 draft, Kieboom was seen as a polished high school shortstop without a true standout tool, but average to above average ability almost across the board. That scouting report didn't exactly bear fruit in his professional debut, as he hit just .244 with 43 strikeouts in 36 games in the Gulf Coast League, but plenty of prospects have gone on to excellent careers after struggling as 18-year-olds in their debuts. Long term he may outgrow shortstop and move to third base, but he has the arm for the position, and his ultimate fantasy value will depend on how his power stroke develops as he likely won't offer much on the basepaths. He's not an elite dynasty asset by any means, but assuming he bounces back in 2017, Kieboom figures to provide the Nationals with solid production with both his glove and his bat beginning in the early 2020s.
