The bench is full of experience at the MLB level. I don't see much reason to clog up AAA with veteran retreads. Let the kids play at that level.
AAA has Larnach, Lee, Severino, Miranda, Martin, Camargo, Woods Richardson, Festa, Headrick and Ohl who should all be playing regularly. That's 6 position players and 4 starting pitchers. The AAA bullpen is already full of non-roster invites.
