Cubs 11, Nationals 1: Nate Schierholtz hit two home runs and drove in six runs, Donnie Murphy also went deep twice and Dioner Navarro added a three-run shot as host Chicago posted its most lopsided victory of the season.

The outburst came in support of Jeff Samardzija (7-11), who struck out five, allowed one run on six hits and did not issue a walk in his third career complete game. Wilson Ramos broke up the shutout with a solo homer to left in the seventh, the only extra-base hit for Washington.

Chicago had scored only 12 runs in its previous eight home games, a span that included five shutouts. The Cubs wasted no time jumping on Jordan Zimmermann (14-7) as Junior Lake led off the bottom of the first with a double and Navarro drew a one-out walk ahead of Schierholtz's three-run blast.

Schierholtz added an RBI double in the third and made it his fourth career two-homer game in the seventh when he ripped a 3-2 fastball from Fernando Abad just inside the right-field foul pole and onto Sheffield Ave. The blast was his 18th, tying Anthony Rizzo for the team lead.

Murphy led off the fourth and eighth with homers - giving him six in 13 games with the Cubs - and Navarro drove a three-run shot to right-center in the fifth. Three of the five homers came against Zimmermann, who was tagged for eight runs on seven hits over five innings.
