The biggest factor is TV. They want every game stand alone. When the first expanded the playoffs, they had all 4 ALDS series going at once, and no one liked it. So I'd expect tomorrow to stay a night game, and Wednesday and Thursday to be day games, because they've already scheduled the games in San Francisco as night games those days. I doubt they'd move Thursday's NLCS game to day to give us a night game.
Day baseball. Get ready.
