You answered you own question! You are in southern Nevada (Las Vegas) which is IN the Angles territory. Local stations have the rights to this broadcast. If any 'local' stations decided not to pick up the game, you're simply 'out of luck'.CJTE said:
Here once again is a link to the MLB territories:

as you can see, your 'local' area is claimed by several teams, including the Diamondbacks, the Dodgers, the A's, the Giants, the Padres, AND the Angles. Basically, good luck getting ANY national broadcasts of any of those teams unless the national broadcaster has paid for the 'full rights' to broadcast the game. Obviously, TBS has not, letting the 'local' broadcasters retain those rights to this game.
