If Zack Greinke can improve upon two previous starts at Wrigley Field, the Los Angeles Dodgers have a chance to rebound from a rough series on their final trip of the season. Greinke can end his road struggles against the Chicago Cubs by winning a third straight start while helping the Dodgers avoid matching a season high with their third consecutive defeat Thursday night. Los Angeles (86-66) began its trip by taking two of three in San Francisco, but after Monday's 11-3 win in Colorado was outscored 26-6 in the final two games of that set. The Dodgers lead the Giants by two games in the NL West after a 16-2 loss Wednesday.
