Assuming Candelario gets traded soon I'd imagine Alu/Libscomb/House all get bumped up level.
Does Libscomb have a future move to 2nd base in his future? House could very well be up in 2024 with Woods and Crews if he keeps his pace.
Or Lipscomb shifts to 1B. I remember a great 3B who went to first when his shoulder got too bad. A 1B needs to play like an infielder, the way La Roche did. Or Don Mattingly and Keith Hernandez were, to speak of important stars. (Not to imagine that Lipscomb will hot or field like Hernandez and Mattingly...)
Still, a team needs depth. No way to be certain that any prospect will become am all-star, or even a regular. Having Alu, Lipscomb, House, and Yoyo Morales can only help.
Now, if the Nats had another shortstop coming up, and one who can hit...
