ATLANTA — Matt Wisler is trying to close out the season on a strong note after struggling at times for the Atlanta Braves.

"I've had my ups and downs this year," he said. "I've shown that I can be really good and I've shown I can be really bad. It's just a matter of not taking any start for granted."

Adonis Garcia drove in three runs, Wisler pitched five-plus innings and Atlanta beat the Washington Nationals 6-2 in a rain-shortened game Sunday.

The game was official with two outs in the bottom of the seventh. The two delays totalled 2 hours, 57 minutes.

Washington has dropped two straight and needs any combination of six Nationals wins and six New York Mets losses to earn its third NL East title in five years.

After a 1-hour, 7-minute delay in the top of the sixth, the Braves scored three runs in the bottom of the inning to make it 6-2 on Garcia's two-run single and Freddie Freeman's RBI double.

Wisler (7-12) allowed two runs, five hits and struck out two in 5 2/3 innings to earn the win.

He faced a limited lineup as Nationals manager Dusty Baker gave sluggers Daniel Murphy and Anthony Rendon the day off and used Ryan Zimmerman as a pinch-hitter.

"Today I thought I came out aggressively, made them put the ball in play," Wisler said. "They were swinging kind of early. They weren't squaring up a lot of balls like they were the last game (he faced them)."

Joe Ross (7-5), reinstated from the disabled list after missing 66 games with right shoulder inflammation, took the loss. Ross, on a pitch count, allowed one run and six hits, one run and struck out five in three innings. It was his first start since July 2.

"It's a welcomed sight to see him back," Nationals manager Dusty Baker said.

Ross trailed 1-0 in the second on Jace Peterson's RBI single. He gave up three singles to begin the third, but retired the next three batters to escape the jam.

"Pitched myself into a jam and was able to work out of in the third," Ross said. "Felt good, and that's the main thing I was concerned with today. I could have kept pitching, but probably best to keep it to three innings."

Reynaldo Lopez took over in the fourth and trailed 3-0 on Dansby Swanson's RBI double and Garcia's RBI single.

Washington made it 3-2 in the sixth. Trea Turner tripled and Jayson Werth doubled off Wisler. After the first delay ended, Bryce Harper's single off Ian Krol scored Werth.

Wisler is 3-3 with a 4.83 in five career starts and one relief appearance against Washington.

The Nationals went 15-4 against Atlanta this season and 36-13 in the series since June 21, 2014. They played their last game at Turner Field with the NL-worst Braves moving to a new ballpark next year.
