Howie Kendrick and Anthony Rendon homered and Max Scherzer returned from injury as the visiting Nationals beat the Pirates 7-1.
Washington won three of four games in the series, outscoring the Pirates in the four games 32-6.
Victor Robles and Asdrubal Cabrera added RBI singles for the Nationals, who broke things open with a four-run eighth.
Adam Frazier homered for Pittsburgh, which has lost six of its past eight games.
Scherzer, who came off the injured list (back and shoulder) for his first start since July 25, pitched four innings, giving up one run, the Frazier homer, and four hits, with three strikeouts and one walk.
The Nationals indicated Scherzer would be on a pitch count after the time off. He threw 71.
