How has he lost it? No one has outplayed him
Kieboom was given 3B in 2020. He hit .202 with a .556 OPS. Josh Harrison also played some 3B that year. Kieboom was given 3B in 2021, and hit .207 again with .619 OPS, as Stalin Castro won the job. He had his surgery in March, 2022, but the Nats had brought in Maikel Franco, suggesting that the organization did not trust Kieboom at 3B.
