Cubs reliever Carlos Marmol took the mound with the game knotted at five apiece in the top of the ninth, but struggled with his command per usual and walked a pair of batters. Marmol's early control problems would quickly prove costly, as the inconsistent right-hander soon gave up consecutive RBI singles to San Francisco hitters to put the Giants ahead on the scoreboard.
Starter Travis Wood scattered seven hits over 5.2 innings, but took the loss to drop to a woeful 4-12 on the season. Offensively, outfielder Alfonso Soriano continued his second-half power surge despite the outcome, by belting out his 25th home run of the season in the fifth inning. The 36-year-old Soriano now has nine RBI over his last 10 games and could be in store for his first 30+ homer season since his debut in a Cubs uniform back in 2007.
