LOS ANGELES - Rookie Ian Stewart homered and drove in a career-high five runs and the Colorado Rockies beat the Los Angeles Dodgers 8-3 n Tuesday night for their fourth straight victory.

The loss was the second in eight games for the Dodgers, who dropped one game behind NL West-leading Arizona. Brad Hawpe and Matt Holliday homered for the Rockies, who are eight games back.

Stewart hit a two-out, two-run single in the first off Hiroki Kuroda (7-9) and added a three-run homer off Hong-Chih Kuo in the eighth to cap a four-run rally that gave the Rockies a five-run lead. Holliday opened the third of his four hits, his 24th homer off Jason Johnson.

Stewart, a left-handed hitter, is 14-for-33 against left-handers this year, and five of his last 12 hits have been homers. The Rockies have hit at least one homer in 12 of their last 13 games, and have a total of 20 during that time.

Ubaldo Jimenez (9-11) earned the victory despite working a shaky five innings. He allowed eight hits and three runs with one walk and seven strikeouts before being relieved by Luis Vizcaino to start the sixth. Colorado relievers blanked the Dodgers the rest of the way.

Willie Tavares and Holliday singled and Garrett Atkins walked before Stewart hit his first-inning single.

Matt Kemp doubled to open the bottom of the first and scored on a ground-rule double by Jeff Kent — the first of his three hits.

Hawpe hit his 22nd homer in the third on the first pitch after Holliday's shot up the middle glanced off Kuroda's left ankle into short right field for a one-out single.

The Dodgers scored twice in the fourth to draw within one run after Jimenez retired the first two batters. Nomar Garciaparra singled, took third on a double by Casey Blake and scored on Yorvit Torrealba's passed ball. Jimenez walked Kuroda, who came to the plate hitting .100, before Kemp hit an RBI double. Andre Ethier then struck out for the third time.

Kuroda, who had given up one run in each of his previous three starts, retired his last nine batters before being lifted for a pinch-hitter. He allowed six hits and four runs in six innings while walking one and striking out three.

With the Rockies leading 4-3, the Dodgers loaded the bases with two outs in the seventh against Manny Corpas on singles by Kent and Manny Ramirez and a walk to James Loney before Russell Martin flied to right.
