For the second straight day, the Los Angeles Dodgers leaned on a big inning. For the second straight day, the St. Louis Cardinals found themselves hopelessly behind. Juan Rivera homered and knocked in three runs and the Dodgers scored an early knockout with a six-run third, completing their first road sweep of the season with a 9-4 victory on Wednesday. The Cardinals have been swept twice at home and Rivera homered in both, helping the Blue Jays take a three-game set from June 24-26 before the Dodgers traded for him in July.
