Apple only broadcasts the Friday Night Baseball games (2 pre-scheduled games per Friday night). Other baseball games are broadcast by various other parties (as scheduled through MLB).
Apple can send out their FNB streams to all Apple TV+ subscribers (that wasn’t a requirement initially in 2022), in FNB-supported countries — no local blackouts. It is not about Cleveland per se. Are you an Apple TV+ subscriber? Else not sure what failed for you. What happened exactly when you tried to watch?
