LOS ANGELES — Adrian Gonzalez homered twice and Zack Greinke gave the Los Angeles Dodgers the clutch performance they needed in a 6-4 victory over the Cardinals on Wednesday that trimmed St. Louis' lead to 3-2 in the NL championship series. Carl Crawford and A.J. Ellis also went deep for the Dodgers, who rediscovered their power stroke just in time to save their season. They held in the ninth, when St. Louis scored twice off closer Kenley Jansen before he struck out pinch-hitter Adron Chambers with two on to end it.
