PHOENIX -- Josh Collmenter pitched eight strong innings and Jordan Pacheco homered as the Arizona Diamondbacks routed the Colorado Rockies 9-1 on Wednesday night.

Yasmani Tomas finished 2-for-4 with three RBIs, Paul Goldschmidt had three hits and an RBI and Mark Trumbo added a run-scoring single for the Diamondbacks, who have won two straight after a season-worst four-game losing streak.

Arizona outscored the Rockies 21-6 over the final two games of the three-game set.

Colorado, which did not have a starter last more than five innings in the series against the Diamondbacks, has lost three of four.

Collmenter (2-3) went a season-best eight innings, scattering five hits. He struck out six and did not walk a batter for the second straight start.

After allowing an unearned run in the first and a leadoff single to catcher Nick Hundley in the second, Collmenter was dominant. Hundley was erased on a double play to end the second and Collmenter retired 12 consecutive Rockies before left fielder Corey Dickerson doubled into the right-field corner with one out in the sixth.

Rockies starter Jordan Lyles (2-2) lasted five innings, allowing seven runs -- six earned -- on eight hits with five walks. He struck out one, his lowest total of the season.

Lyles followed a similar pattern as Collmenter early, giving up two runs -- one earned -- in the first before and then holding the Diamondbacks scoreless over the next three innings, albeit with three hits and walk allowed along the way.

Lyles' control abandoned him in the fifth.

He walked center fielder Ender Inciarte to start the inning, and after a sacrifice bunt by second baseman Chris Owings, walked Goldschmidt. Trumbo hit a towering fly ball to the warning track in left for the second out, but Lyles walked left fielder David Peralta. Tomas took one pitch out of the strike zone before lining a single into right, scoring Inciarte and Goldschmidt to make it 4-1.

Pacheco, the former Rockies catcher, followed with his first Diamondbacks home run to extend Arizona's lead to 7-1.

Both teams capitalized on errors to score in the first inning.

Colorado took a 1-0 lead in the top of the inning as shortstop Troy Tulowitzki doubled to left and went to third when Owings couldn't handle a grounder by first baseman Justin Morneau. Third baseman Nolan Arenado followed with a single to center, scoring Tulowitzki for a 1-0 lead.

It was the Diamondbacks' turn in the bottom of the inning. Inciarte beat out an infield single to third, and Goldschmidt singled one out later. Inciarte appeared to be picked off second base by Lyles as he and Goldschmidt broke on a double steal. However, second baseman Daniel Descalso's throw to third hit Inciarte in the helmet and caromed toward the Arizona dugout, allowing Inciarte to score and Goldschmidt to advance to third.

Trumbo singled to center, his fifth consecutive hit, scoring Goldschmidt to put the Diamondbacks ahead 2-1.

NOTES: Arizona RHP Archie Bradley was placed on the 15-day disabled list with a sinus fracture the day after taking a line drive off the side of his face. The Diamondbacks recalled RHP Enrique Burgos from Double-A Mobile. Burgos was tied for the minor league lead with six saves and had not allowed a run while scattering three hits in 6 2/3 innings. ... The 26 runs scored in the series' first two games shouldn't come as a surprise. Colorado and Arizona entered Wednesday's game as two of three teams with six players hitting .300 or higher. ... Rockies 2B DJ LeMahieu, the major league batting leader at .406 through Tuesday, did not start. ... Colorado RHP Rafael Betancourt turned 40 on Wednesday, giving the Rockies two relievers 40 or older. RHP LaTroy Hawkins is on the 15-day disabled list due to biceps tendinitis.
