Cubs 2, Nationals 1: Kurt Suzuki's throwing error in the ninth inning allowed the go-ahead run to score as visiting Chicago claimed the rubber match of the three-game series.
Nationals starter Gio Gonzalez didn't allow a baserunner until Dioner Navarro's infield single leading off the sixth, but the Cubs rallied against Washington's bullpen. Starlin Castro tied it with a two-out RBI single against Drew Storen in the eighth, and Chicago stole a run in the ninth.
After consecutive singles by Alfonso Soriano and Julio Borbon to start the inning against Rafael Soriano (0-1), the Cubs put on a double steal with one out, and Suzuki's throw was well wide of third, allowing Soriano to scamper home with the go-ahead run.
Cubs starter Scott Feldman held the Nationals to one run on five hits over six innings and Kyuji Fujikawa and James Russell (1-0) each worked a scoreless inning to get the ball to Kevin Gregg, who retired the side in order in the ninth for his sixth save in as many opportunities.
Navarro and Cody Ransom each had two hits for the Cubs, who have won consecutive road series.
