Ryan Zimmerman had two hits and drove in a run, Bryce Harper 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 four 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.

Haren (8-11) kept the Cubs off-balanced and frustrated despite not throwing a pitch faster than 89 all night. Rafael Soriano gave up a leadoff homer to Donnie Murphy in 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.
