The two clubs resume their three-game series on Saturday night.
"A great road trip is 8-2," outfielder Marlon Byrd said. "We already have one loss into that so we've got to pick it up tomorrow and try to score some runs early. Their offense is potent. They know how to play here. They love playing here and hitting here. We have to try to back them against the wall early in the game and help our pitching out."
