Denver, CO (SportsNetwork.com) - Hyun-Jin Ryu pitched six solid innings and remained unbeaten on the road this season, as the Los Angeles Dodgers topped the struggling Colorado Rockies, 7-2, at Coors Field.

Dee Gordon went 3-for-4 with a pair of triples, drove in three runs and scored twice. Hanley Ramirez added two RBI for the Dodgers, who won for just the third time in their last nine games.

Ryu (7-2), who surrendered eight hits and a pair of runs, won his fourth consecutive start since coming off the disabled list on May 21. The left- hander has given up just four runs in six road starts this season, posting a 5-0 mark with a 0.95 ERA.

"He's basically been a fastball, changeup guy," Dodgers manager Don Mattingly said of Ryu. "He's throwing more breaking balls now."

Right-hander Eddie Butler (0-1) lost in his major league debut after making 11 starts for the Double-A Tulsa Drillers. Butler surrendered 10 hits and six runs over the first 5 1/3 innings.

"You can't pitch over the middle of the plate. I learned a few things," Butler said.

Drew Stubbs homered and Charlie Culberson slapped an RBI triple for the Rockies, who lost their eighth in a row.

Gordon tripled to right on the second pitch of the game. Ramirez followed with an RBI groundout.

Drew Butera's double to center scored Andre Ethier in the second; and the Dodgers tacked on two runs in both the fifth and sixth for a 6-0 cushion. Gordon's triple to right-center scored Ryu, who had doubled to start the fifth. Gordon, who came home on a Ramirez base hit to left, added a two- run bloop single to right-center in the sixth.

Stubbs went deep with one out in the sixth, and Culberson's triple later in the frame plated Michael McKenry.

Matt Kemp sacrifice fly to right scored Yasiel Puig in the ninth.
