Ryan Zimmerman had two hits and drove in a run, Bryce Harper also had two hits and scored a crucial ninth-inning run, and Dan Haren pitched six strong innings to help the Washington Nationals beat the Chicago Cubs 4-2 Tuesday night.
Zimmerman had two doubles and could have had two more hits as he lined out to third base in the third inning to start a double play and hit a hard shot at the center fielder in the seventh.
Harper doubled leading off the ninth and scored on Ian Desmond's RBI single to right field. Denard Span, a late-inning defensive replacement, added a run-scoring single for the Nationals' final run.
Haren (8-11) kept the Cubs off-balance and frustrated despite not throwing a pitch faster than 89 all night. He allowed just five hits and improved to 4-2 with a 2.20 ERA in eight starts since coming off the disabled list on July 8.
Rafael Soriano gave up a leadoff homer to Donnie Murphy in the bottom of the ninth before getting the last three outs for his 32nd save in 38 chances.
Cubs starter Chris Rusin (2-3) gave up two runs and 10 hits in 5 2-3 innings, managing to work out of jam after jam with minimal damage. However, the Cubs' offense -- which scored just 12 runs in eight home games before an 11-run outburst on Monday -- went back into its Wrigley Field struggles.
The Nationals took a 2-1 lead in the sixth inning as Zimmerman opened with a double, moved to third on Jayson Werth's single and scored one out later on Tyler Moore's run-scoring infield single.
Washington went ahead in the top of the first. Ian Desmond reached on a fielder's chose when the Cubs failed to turn a seemingly routine double play, and then scored on Zimmerman's double to left field.
The Cubs tied it in the bottom of the fourth on Brian Bogusevic's first homer of the season, a two-out shot to right field that landed in the first row of the bleachers.
