So maybe this ends up having adverse impacts? The rule is to urge teams to not keep players in the minors to max out their period of control. Maybe teams see this and just decide to hold players back long enough that they won't get consideration for ROY because they didnt' get enough playing time yet exceed the max # of at bats so they aren't considered a rookie in the next season.
Maybe this doesn't transpire but this sure didn't help the O's losing a year of control. No matter how you slice it its going to cost them. Lose a year or give him an extension that is more costly.
