ATLANTA - The Nationals have followed a five-game losing streak with two close losses that were painfully familiar to Jayson Werth.

Washington's struggles against Atlanta continued as Justin Upton hit a home run with one out in the 10th inning to power the Braves to a 3-2 win over the Nationals on Friday.

The loss followed a 4-3 home loss to the Giants on Thursday night in a game decided by a three-run homer in the ninth.

Back-to-back tough losses?

"Boy, you aren't kidding," Washington manager Davey Johnson said.

Werth said there have been far too many close losses this season.

"It's not easy losing, that's for sure," the right fielder said. "It's kind of been the story of the year so far; we play just good enough to lose."

The Braves, who swept a three-game series at Washington on Aug. 5-7, lead the season series 11-3, including six straight wins.

Jason Heyward had two hits and scored one run for Atlanta, which stretched its lead over the second-place Nationals to 15 1/2 games.

"There's a lot of baseball to be played," Upton said. "Our lead is pretty big right now, but crazier things have happened in baseball."

Upton's 23rd homer to left-center came on a 2-2 pitch from Ian Krol (1-1).
