Colorado's Miguel Olivo hit his 100th career homer.

Carlos Monasterios (1-0), Los Angeles' seventh pitcher, threw the final 2 2-3 innings. In the 13th, he had allowed runners at second and third with one out. But Dodgers third baseman Casey Blake, who earlier had hit two homers, threw out Ivan Rodriguez at home plate to end the game.
