With Trea Turner at shortstop and Starlin Castro at second base, the Nationals have two reliable veterans at the two positions Carter Kieboom has always played.
So now, the Nationals' top prospect is competing for the starting third base job with seasoned veteran Asdrubal Cabrera. Once one of the best shortstops in baseball, Cabrera has fallen off defensively and has limited range nowadays, though he was still a key contributor to the Nationals' World Series championship in 2019.
Instead of viewing Kieboom as just his competition and doing everything he can to win the job, Cabrera has taken on the role of mentor for the 22-year-old infielder.
"(Cabrera) takes ground balls with (Kieboom) every day," Martinez said, according to MASN's Pete Kerzel. "I've asked him, ‘Hey, you need to take ground balls at second, too, and short sometimes.' Religiously, for the purpose of being with Carter, he stands with Carter, helping him with his throws, making sure he understands that footwork is important when he's throwing. ... He talks to him all the time about a bunch of different things, how to play positions, not take your at-bats to the field. He's been unbelievable with him, he really has. It's been good for Carter."
Kieboom has struggled with errors through the early days of spring ball, which is to be expected considering he's a young player at a position he's never played regularly on the professional level. While a bunch of errors in February are nothing to get too concerned over, Kieboom will have to cut those down in March if he wants to win the job.
Cabrera is seen as the backup plan at third if Kieboom can't secure the job during spring training. The 34-year-old is entering his 14th season and would probably be better maximized if he didn't have to play every day.
If Kieboom isn't ready though, it wouldn't be the best idea for the Nationals to force it. So over the course of the next three weeks, we'll see just how much Cabrera can help the youngster.
