DENVER – David Ross and Jayson Werth homered and Wilson Alvarez pitched five solid innings, helping the Los Angeles Dodgers beat the Colorado Rockies 3-2 on Thursday.

Alvarez allowed two runs and four hits to win his third straight decision, combining with Duaner Sanchez, Darren Dreifort, Guillermo Mota and Eric Gagne on the four-hitter. The Dodgers have won 13 of their last 17, and 10 of 13 on the road.

Todd Helton hit his 22nd homer and Jamey Wright had another solid outing for the Rockies, who couldn’t mount another late-inning comeback against Los Angeles’ bullpen.

The Rockies didn’t have a hit after Alvarez left in the fifth, a day after rallying for the go-ahead run against the Dodgers’ bullpen in the eighth inning of a 5-4 victory.

Gagne got the final out in the eighth, and pitched a perfect ninth for his 30th save in 31 chances.

The Dodgers got off to a good start against Wright, with Werth hitting a long solo homer in the first that hit the base of the concourse behind the foul pole in left.

But that was about it.

The Dodgers had a runner on third with one out in the third inning after Ross tripled. Wright followed by getting Alvarez on a comebacker and Cesar Izturis on a flyout to end the inning.

Alex Cora led off the fifth with a double, but was left standing there after Wright got a pair of popups and a groundout to finish off the inning.

Alvarez (6-3) was just as good in the early going.

Aaron Miles led off the first inning with a double, but the Rockies didn’t get another hit off the left-hander until Helton led off the fourth with his third homer in four games.

Charles Johnson put the Rockies up 2-1 in the fifth with a line-drive, RBI double over Milton Bradley in center.

The Dodgers took the lead back in the sixth, when Scott Dohmann (0-1) hung a 1-2 curveball that Ross hit over the wall in left for a two-run homer. Wright walked Juan Encarnacion just before that and was pulled after giving up two runs and seven hits in 5 1-3 innings.

Alvarez was lifted for a pinch hitter in the sixth after striking out six, walking two and hitting a batter.

Notes: Colorado played with a short bench for the second straight game because C Todd Greene (hamstring) and INF Luis Gonzalez (knee) are still nursing injuries. … Werth started an impressive double play to end the sixth, catching Jeromy Burnitz’s drive against the wall and throwing the ball back in from his back. Two relay throws later, Preston Wilson was doubled off first. … Los Angeles is 50-0 when leading after eight innings. … Colorado 3B Vinny Castilla was 0-for-4, ending his hitting streak at 11 games.
