ATLANTA — Christian Bethancourt had a three-run single to help the Atlanta Braves beat the Washington Nationals 3-1 on Wednesday night and preserve their fading playoff hopes.
The Braves, who snapped a five-game losing streak, began the day 5 ½ games behind Pittsburgh for the second NL wild card.
Stephen Souza Jr. hit his first career homer for the Nationals. Washington manager Matt Williams gave his regulars a day off one day after the Nationals clinched the NL East title.

The Braves loaded the bases against Ross Detwiler (2-3) in the sixth. Bethancourt's sharp grounder bounced off first baseman Tyler Moore's glove and into right field.

Shortstop Danny Espinosa's throwing error allowed Bethancourt to advance to third base.
Gosselin had three hits.
