Matt Kemp went 4-for-5 with four RBI and Chad Billingsley fired 7 1/3 shutout innings Saturday in the Los Angeles Dodgers\' 10-0 rout of San Francisco. Kemp set the tone with a two-run homer in the first inning, later adding a pair of run-scoring doubles, and Hanley Ramirez chipped in with three RBI for the Dodgers, who clinched their three-game series against their National League West rivals. A.J. Ellis went 2-for-4 with a solo homer as second-place Los Angeles pulled to within one game of division-leading San Francisco. Billingsley (6-9) didn\'t issue a walk and scattered four hits in taming the Giants, striking out two. Javy Guerra pitched 1 2/3 scoreless frames to complete the whitewash. San Francisco starter Barry Zito (8-7) was touched for four runs on seven hits over 5 1/3 innings, absorbing his first loss in three starts.
