With both teams already assured playoff spots, the Rockies cut the Dodgers' division lead to one game. Colorado needs to sweep the three-game series to win the West.

The Rockies won their fifth in a row and Dodgers lost their season-worst fifth straight. Clayton Kershaw is scheduled to start Saturday for Los Angeles against Jorge De La Rosa.

Troy Tulowitzki hit a two-run homer and Yorvit Torrealba had a two-run double for the Rockies.

Dodgers star Manny Ramirez struck out all four times up, matching a career high. He fanned in the seventh inning with two runners on base.

Jimenez (15-12) allowed one run and two hits, and matched a season high for strikeouts. The right-hander lowered his ERA to 3.51, the best by a starting pitcher in franchise history.

Huston Street, the fifth Rockies pitcher, got four outs for his 35th save in 37 chances.

Randy Wolf (11-7) gave up two runs and five hits over five innings. He was 6-0 with a 2.45 ERA in his previous nine outings.

Wolf needed 20 minutes and 37 pitches to get out of the first inning. He gave up a two-out, two-run double by Torrealba that struck the wall in right-center on the fly.

Tulowitzki greeted Ronald Belisario with his 32nd homer, a drive deep into the pavilion seats in left-center on an 0-2 pitch, to give Colorado a 4-1 lead. Tulowitzki connected after Todd Helton led off the seventh with a double against Scott Elbert.

The Dodgers scored twice in the seventh on Russell Martin's leadoff homer against Matt Daley and an RBI single by Andre Ethier against former Dodgers reliever Joe Beimel that narrowed the gap to 4-3.

NOTES: Ramirez has struck out four times in a game five times. ... Dodgers RHP Hiroki Kuroda had an MRI exam that revealed a herniation in his cervical spine, so he is unavailable for the division series. He already has sat out two months with an oblique strain and another three weeks after he was struck by a line drive. ... Hall of Fame manager Tommy Lasorda was honored before the game to commemorate his 60 years in the Dodgers' organization as a player, scout, minor league manager, coach and manager. Fifteen of his players took part in a ceremony on the pitcher's mound, and knuckleballer Charlie Hough threw out a ceremonial first pitch "in relief" of the 82-year-old Lasorda.
