Carter Kieboom Scouting Report- LINK


Kieboom had a banner regular season in 2018, finishing the year in Double-A and holding his own as a 20-year-old against much older competition. He turned 21 days after the Fall League started, and the Nationals continued to challenge their young star prospect by sending him to AFL after his longest season as a pro. Kieboom looked tired at times this fall, hitting for less power than he’s capable and moving a bit worse defensively. Still, the pure swing, contact ability, and mature feel for the strike zone all showed through. He moved between SS and 2B, getting good reps at both positions.


The Nationals have showed they aren’t afraid to rely on young players if they’re ready. Kieboom was out in AFL for a reason, as he has a chance to contribute to the big club in 2019 if he performs and has a good Spring Training. If Kieboom can stay at shortstop, there’s all-star potential given his offensive upside. He’s a safe bet to be at least a solid regular.
