Some pitchers just aren't good on the road. That's certainly been the case this year for Miami's Wei-Yin Chen. He has a 10.27 away ERA. Opponents are batting .350 against him on the road. The Marlins' bullpen has imploded so Chen can't expect much help there. The Marlins have surrendered 38 runs in their last five games, an average of 7.6 runs.

The Nationals are averaging 5.2 runs per game in their last seven contests. They've seen Chen twice this season. Chen has a 6.17 ERA versus Washington this year.

The Marlins could do damage, too, facing journeyman Tommy Milone. He's only in Washington's starting rotation because of an injury to Stephen Strasburg. The Marlins faced Milone on July 26 reaching him for three runs on eight hits in five innings.

Milone has a 5.24 ERA and 1.43 WHIP on the year. Milone has allowed nine runs during his last two starts spanning 9 1/3 innings giving up a staggering 20 hits during this time frame.

Ted Barrett is slated to be the home plate umpire. The Over has cashed 68 percent of the time this season in the 22 games Barrett has been behind the plate.
