Denver, CO (My Sportsbook) - Garrett Atkins' first hit of the season -- a two-run homer -- highlighted a five-run third inning, as the Colorado Rockies defeated the Philadelphia Phillies, 10-3, in the home opener at Coors Field.

Ryan Spilborghs was 3-for-5 with two doubles, two RBI and two runs scored for Colorado, which took two of three in Arizona to begin the 2009 campaign. Clint Barmes had two hits and scored three times, while Todd Helton drove in three.

Jason Marquis (1-0), who was picked up from the Cubs in the offseason, continued his success at Coors Field, allowing two runs and five hits with two walks and as many strikeouts over seven solid innings. The veteran right- hander is now 4-0 in five starts in the Mile High City. Marquis also helped his cause at the plate, going 2-for-2 with a double and a run batted in.

"Jason came out and threw the ball, and the bats got rolling," said Barmes. "We'll definitely take this win. I don't think we could have hoped for anything better."

Coming off a stellar postseason a year ago in which he emerged as an elite pitcher, punctuated by capturing MVP honors in both the NLCS and World Series, Cole Hamels struggled in his season debut for Philadelphia. The lefty was slated to start on Opening Day, but elbow issues during spring training delayed his start.

Hamels (0-1) was hit hard by Colorado, yielding seven runs on 11 hits with a walk and one strikeout in 3 2/3 innings to take the loss.

"You know, if my arm was causing my ineffectiveness, I would have definitely have taken myself out, because that is not going to help the team win," said Hamels. "Giving seven-spots every time you go out just because you are trying to be tough and muscle through things is not going to be beneficial whatsoever."

Jayson Werth went 4-for-4 with two doubles, a homer and three runs scored for the Phillies, who are off to a 1-3 start. Pedro Feliz knocked in the other two runs.

The Phillies jumped out to a 1-0 lead in the second inning when Werth led off with a double and later scored on a Feliz sacrifice fly.

Colorado then put up a crooked number in the third. Barmes doubled to lead off the frame and raced home after Marquis' grounder found a hole on the left side of the diamond. One out later, Spilborghs lined a double to right and Helton's ground out plated Marquis before Atkins stepped in and homered to left field. Brad Hawpe then hit a ground-rule double and Troy Tulowitzki followed with an RBI triple.

Philadelphia got a run back in the top of the fourth, as Werth, once again, smacked a double to begin the inning and scored following a pair of groundouts, the second one from Feliz.

The Rockies plated two more runs in the bottom half. Barmes had a leadoff single, advanced to second on a sac bunt, took third on a ground out and waltzed home on a double by Spilborghs. Helton then slapped a base hit past a diving Ryan Howard at first for a 7-2 lead.

Colorado added three more runs in the eighth off Chad Durbin on bloop singles by Dexter Fowler and Spilborghs and a sac fly from Helton.

Werth went deep to open the ninth inning.
