2020 Fantasy Outlook
It was a three-part season for Kieboom, who peaked (.379/.506/.636) in 18 games at Triple-A before getting promoted and falling flat (17 wRC+) in 11 big-league games. He was then optioned back to the Pacific Coast League, and from there he performed as expected, hitting .289/.391/.458 with a 19.7 K% in his final 90 games. Kieboom was 23% better than the average PCL hitter despite being the youngest qualified hitter on the circuit. Despite significant struggles in his brief MLB stint, his batted-ball profile at Triple-A was encouraging (22.4 LD%, 39.8 Pull%), so it still seems likely that Kieboom will acquit himself well with the bat over the long run. That said, he may not be amazing in any one fantasy category and certainly won't contribute much with his legs. The Nationals brought back Asdrubal Cabrera and signed Starlin Castro, so Kieboom may have to bide his time in the minors for a little while yet. Read Past Outlooks

Getting comfortable at plate
SSWashington Nationals
March 9, 2020
Kieboom went 2-for-3 with a double and an RBI in Sunday's Grapefruit League game against the Tigers.
ANALYSIS
The two-bagger was his first extra-base hit this spring. Kieboom had a sluggish start to camp, but he appears to be getting comfortable in the batter's box and has pushed his slash line up to .250/.419/.292 through 31 plate appearances. The same can't be said for his defense, however -- the 22-year-old committed his third error in 11 games Sunday, a clear sign that his conversion to third base remains a work in progress. Kieboom still has a couple weeks to prove to the Nats' coaching staff that he's ready to handle the position right from Opening Day, and that he won't need more time in the minors to adjust.

2017
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.
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.
