DENVER – Rodrigo Lopez allowed six hits in seven innings for his first win since last Aug. 17, and Matt Holliday backed him with four hits and four RBIs to lead the Colorado Rockies over the Arizona Diamondbacks 11-4.

Last year, Lopez led the major leagues with 18 losses and dropped his final six decisions after beating the New York Yankees on Aug. 17. Acquired from Baltimore in January for two minor league pitchers, Lopez (1-0) gave up two runs – one earned – struck out five and walked none.

Doug Davis (0-1) made his Arizona debut and allowed three first-inning runs – all unearned due to two errors by first baseman Conor Jackson. Davis lasted five innings, allowing eight hits and five walks with six strikeouts.

Holliday had an RBI double in the first, hit his first homer of the season in the seventh off Juan Cruz and added a two-run single in the eighth.

Colorado led 4-2 before breaking open the game with seven runs in the eighth off J.D. Durbin, who gave up seven hits in his first big league appearance since Sept. 23, 2004, and left with a season ERA of 94.50.

Jackson’s sacrifice fly in the fourth brought home Orlando Hudson to pull the Diamondbacks to 3-2. But with one out and runners on first and third, Lopez got Scott Hairston to hit into an inning-ending 5-4-3 double play.

Eric Byrnes led off the second with a home run that hugged the left-field foul pole. Byrnes had two more hits Wednesday and finished the three-game series 7-for-13 with four RBIs.

Jackson had a forgettable first inning, committing two errors as the Rockies scored three runs.

After Jamey Carroll drew a one-out walk, Davis had him picked off first. But when Jackson ran at Carroll in the middle of the baseline, Carroll crouched down and Jackson sailed by, missing the tag. Carroll scampered back to first.

Jackson also lobbed the ball over the head of third baseman Chad Tracy after cutting off a throw home on Helton’s RBI single to center, allowing another run to score.
