The Dodgers used a six-run third inning en route to a 9-4 win over the Cardinals Wednesday afternoon. Juan Rivera and A.J. Ellis hit home runs for Los Angeles, which notched its first road sweep of the season and first three-game sweep in St. Louis since 1993. Jaime Garcia took the loss. Skip Schumaker went 4-for-4 and Gerald Laird homered for the Cardinals in defeat. The Redbirds welcome the Pirates to Busch Stadium tonight for the start of a four-game series.
