Dexter Fowler had three RBI and accounted for two of four Colorado homers as the Rockies rolled to a 7-2 victory over the Los Angeles Dodgers at Coors Field.

Michael Cuddyer and Todd Helton added solo shots to back seven solid innings from Jorge De La Rosa and help the Rockies claim the rubber match of the three-game series. Cuddyer finished with two RBI in the triumph.

De La Rosa (7-3) held the Dodgers to two runs on six hits while striking out five to move to 5-0 in his five Coors Field starts this season.

All four Colorado homers were served up by Matt Magill (0-1), who endured a rough outing in his first-ever appearance at Coors Field. The rookie, called up from Triple-A Albuquerque earlier in the day to fill in for an injured Hyun-Jin Ryu, walked nine batters and was tagged for seven runs -- six earned -- over six innings.

"You're not going to be able to walk that many people...and have any success," Dodgers manager Don Mattingly said. "(Magill) has to get that worked out."

Skip Schumaker went 2-for-3 and knocked in both Los Angeles runs with a second-inning double.

The Dodgers finished a five-game road trip at 1-4.

Helton put the Rockies ahead for good by leading off the bottom of the fourth with his second homer of the series, with the blast snapping a 2-2 deadlock. Colorado tacked on another run later in the frame, when Jonathan Herrera drew one of Magill's multitude of walks, moved up a base on a De La Rosa sacrifice, then came home on DJ LeMahieu's single to center.

Cuddyer further extended the lead with a monstrous shot into the fountains behind center field in the fifth, and Fowler followed a walk to De La Rosa with his second long ball of the afternoon an inning later to up Colorado's advantage to 7-2.

"I was just looking for a good pitch to hit...and I put the barrel on it," Fowler said.

De La Rosa endured a shaky second inning in which he was touched for a pair of runs, but was sharp thereafter in limiting the Dodgers to just four singles over his final four frames of work.

He was staked to an early edge when Fowler socked Magill's second pitch of the day into the bullpen in right center. LeMahieu then walked and was standing on third not long afterward, having stolen second and advancing further when Dodgers catcher Tim Federowicz's throw sailed into center field. He later crossed the plate on a Cuddyer sacrifice fly.

Los Angeles drew even in the second, with Andre Ethier singling and Luis Cruz working a walk in front of Schumaker's liner down the left-field line that got past a diving Carlos Gonzalez.

Ryu was scratched due to bruised left foot he sustained while shutting out the Angels on Tuesday ... Schumaker has now hit safely in 10 straight games ... Fowler had the third multi-homer game of his career and second this season (April 12 at San Diego) ... The Dodgers placed catcher A.J. Ellis (oblique) on the 15-day disabled list to make room for Magill ... The Rockies sent closer Rafael Betancourt (groin) to the DL prior to the game, with veteran reliever Manny Corpas promoted from Triple-A Colorado Springs to fill the roster spot.
