Dish Network has the game starting at 8:30, carried on FSN alternate channel #3.
When I lived in Dallas, I expected Astros games to be pre-empted by Ranger games, even when FSN Guide info indicated it was an Astros game. I'm in Austin and I expected it to be the other way around but the Rangers get far more coverage on FSN, with Houston getting bumped to "alternate channels". Drayton better realize that FSN is screwing him over for the Rangers! Seriously, who likes the Rangers?
