I get it, you are a bit infatuated with rookies in AAA; if they show they belong in the Big Show they will be in the Big Show.
Years back , I read an article how some very talented rookies never really make it out of AAA for more than a hit miss; it said if a team has very good gents in AAA they are not going to send them to another team and remove the talent that can be called up if needed, until they have a place for them, until then, some one as good , or better, if already in the Majors wil stay .
Next spring, if they are as good as you hope , they can show their stuff and the FO will decide where they end up.
