Long Trip

Many times when a team travels across the country, they do so on an off day or following an afternoon game.
Last night, the Dodgers, after losing to the Braves 4-3 when Atlanta scored 3 in the bottom of the 9th, had to get on a plane back to Los Angeles to open up a three-game series tonight with the Rockies (who were off on Monday).
Why didn't they play a day game in Atlanta yesterday?
I'm guessing the Dodgers will be a tired team when they take the field tonight. I'm also guessing they'll win since the Rockies can't play on the road.
