I see where tact you are taking is going, but the Twins have gone from a Leading team to a mediocre team.
They are not the laughing stock of the league but get mention only for there poor performance; if they turn into a AAA and one-half team, they will be the humor point of the league, and fans do not pay to see a AAA and one-half team, that is finding out if they have winners or losers.
Let them play out the year with the starters they started with using rookies only if absolutely necessary.
Leave the rookies in AAA to get experience and come to Training Camp next spring with confidence, not come up and get destroyed psychologically by getting hammered due to not being ready yet.
At least one or two teams have old school rookies who are ready before they even hit AAA, nowadays that is rare, very rare; it seems a lot are not going to last long even in AAA as baseball is run now.
