ATLANTA (AP) -- A.J. Pierzynski and Juan Uribe hit back-to-back homers in a four-run fourth inning and the Atlanta Braves beat the Washington Nationals 4-1 on Wednesday night to end a streak of nine straight losses in the season series.
Rookie Matt Wisler allowed one hit in 5 1-3 scoreless innings to make up for a loss to the Nationals in his last start. Wisler had a run-scoring single in the big fourth inning, his first career hit.
Wisler (2-1) overcame five walks in his rematch against Nationals' right-hander Doug Fister (3-4), who allowed four runs in six innings.
Pierzynski hit a two-run homer to right field off Fister before Uribe followed with his shot over the wall in center.
The start of the game was delayed 2 hours, 9 minutes by rain.
The Braves beat Washington for the first time since the opening game of the season series on April 27 -- also against Fister.
Wisler and five relievers combined to allow only four hits. Jason Grilli had two strikeouts in a perfect ninth for his 22nd save.
The Nationals had runners on first and third with one out in the third and sixth innings. Each time the inning ended with a double-play grounder -- from Yunel Escobar in the third and Wilson Ramos in the sixth.
Denard Span's single off Nick Masset drove in Ian Desmond in the seventh. With two outs and runners on first and third, David Aardsma struck out Danny Espinosa.
The Nationals took only their second loss in their last 11 games, a span that included sweeps of the Braves and Pittsburgh Pirates.
The Braves sent nine batters to the plate in the four-run fourth. Cameron Maybin singled, stole second and scored on Pierzynski's fifth homer. Uribe's homer gave Atlanta back-to-back homers for the first time since April 15 against Miami.
Kelly Johnson had an infield hit and scored from second on Wisler's dribbler through the hole into right field.
HUSTLE FOR HARPER
Nationals manager Matt Williams said before the game he spoke with OF Bryce Harper about not running hard to first base on a fly ball in Tuesday night's win.
"I spoke to him today," Williams said. "It's important for him to be passionate about the way he plays. In every aspect. ... He'll be out there again today and I guarantee if he hits one in the gap he'll go hard."
Nationals: 1B Ryan Zimmerman (left foot plantar fasciitis) hit and fielded grounders but still has some soreness and wasn't ready to run the bases as he continued his rehab with Class A Potomac. "He's progressing. It's still there," Williams said.
Braves: 1B Freddie Freeman (bruised right wrist) is scheduled for more treatment on Thursday. Freeman is eligible to come off the 15-day DL on Friday but is expected to need more recovery time.
Nationals: RHP Max Scherzer will face the Braves for the first time since joining the Nationals. Scherzer was 1-2 in six games, including four starts, against the Braves while pitching for Arizona and Detroit.
Braves: LHP Manny Banuelos is expected to be recalled from Triple-A Gwinnett for his major league debut. Banuelos is 6-2 with a 2.29 ERA at Gwinnett.
