WASHINGTON -- As Atlanta clings to its slim postseason chances, starter Lance Cormier gave the Braves just what they needed.
Cormier allowed two runs and six hits over 6 1/3 innings and the Braves hit three home runs in a 7-3 victory over the Washington Nationals on Wednesday night.
"Lance came up with another gem I thought," manager Bobby Cox said. "His curveball was really working, and that's a great pitch, because nobody can hit that thing."
Atlanta, which has 10 games remaining, is games behind Los Angeles and Philadelphia, the NL wild-card co-leaders. The Braves have been in the playoffs every year since 1991.
Brian McCann hit a three-run homer in the third and Andruw Jones, who had an RBI single in the first, hit a solo shot -- his 36th -- in the fifth. Jeff Francoeur added a solo homer, his 26th, in the sixth.
The Braves have 202 home runs this season, fifth-most in franchise history.
"Especially considering we don't play in a hitter's park," it's impressive, said McCann, who has 21 homers. "We've got a lot of guys with power."
Cormier (4-5) won for the second time in his last three starts. He walked four, struck out five and gave up Ryan Zimmerman's 19th home run in the first inning.
"I'm just trying to continue to believe that I've got the stuff to be a starter," Cormier said. "Just go out there when you have the chance to start and give it everything you have."
Ramon Ortiz (10-15) allowed five runs and eight hits, including the home runs to McCann and Jones, in five innings. In his last eight starts, he is 1-6 with an 8.08 ERA. He has lost all three games since his near no-hitter against St. Louis on Sept. 4, and he is tied with the Cardinals' Jason Marquis for the National League lead in losses.
"Every time I make a mistake -- home run," Ortiz said. "I don't want to think about my last three games. I have to keep pitching well. I want to finish strong. I want to do the best I can my last three games."
Zimmerman's homer gave him 99 RBI for the season, tops among NL rookies. He scored in the fourth on Bernie Castro's infield single.
Cormier left with one out in the seventh after Nook Logan reached on a bunt single and Jose Vidro walked. Reliever Chad Paronto forced groundouts from Alfonso Soriano and Felipe Lopez to end the threat.
Edgar Renteria had an RBI double in the ninth for Atlanta.
Brian Schneider of the Nationals doubled in the ninth to extend his hitting streak to a career-high 11 games. He scored on a two-out single by Brandon Harper.
