I don't think they're going to keep him down for keeping him down's sake, but he still has fewer than 100 plate appearances in Triple-A, where he was good but not other-worldly in a SSS. I trust the org to make the smart decision. I've been on the Triple-A train for a while but I have come around on the possibility of him breaking camp with the club.
The problem is, if he starts in Norfolk he probably won't be down for long, and that leaves the team exposed for him finishing top 2 in ROY. So that tilts it toward having him on the OD roster. Plus, the PPI is not just for ROY, but for top 3 in MVP and Cy Young in any pre-arb season, so it is *possible* that Carter wins ROY but Holliday finishes 3rd in MVP in two years and nets the team a pick. Probably not likely enough to enter the equation, just something I forgot about until recently.
Credit to the union for making this interesting. Three years ago it would have been "keep him down for a month" and we would all move on.
