Jordan Zimmermann pitched eight strong innings, Asdrubal Cabrera homered and the Washington Nationals kept up their dominance of two-time Cy Young Award winner Tim Lincecum, beating the San Francisco Giants 6-2 Saturday. Jayson Werth added a pair of RBI singles and Denard Span had a triple and single for the NL East-leading Nationals, who resumed their winning ways one night after San Francisco ended their 10-game winning streak. Zimmermann (9-5) got off to a shaky start when Angel Pagan led off with a double and Hunter Pence followed with a home run.
