Ellis' solo home run in the fourth got the Dodgers on the board, but the Giants got the run back in the bottom of the frame on a run-scoring fielder's choice off the bat of Blanco.
A big fifth inning saw the Dodgers surge ahead. With one out, Kemp got the scoring started with a two-run single and back-to-back singles from Skip Schumaker and Juan Uribe later in the frame each drove in a run.
