Ok, not saying you’re wrong but here’s what BTS just posted
Unowned players with no MLB experience that are added to a real life roster can only be added at 8PM ET two days after their MLB debut. So if they debut on Tuesday, they can be added at 8PM on Thursday. Commissioners reserve the right to manually add any such player to actual waivers, and owners can request that any such players are added to waivers.
Am I misinterpreting? Please explain it to me. Sorry im new to this stuff.
