PHOENIX -- Aaron Cook finally added to his franchise-leading wins total for the Colorado Rockies.
It sure took a while.
Cook went six innings for his first victory of the season, and Dexter Fowler and Mark Ellis each had three hits and drove in a run as the Colorado Rockies beat the Arizona Diamondbacks 8-4 on Friday night.
"It's good to get that monkey off my back, get a win and give us a chance to win a ball game," said Cook, the Rockies' career leader with 70 wins. "It was aggravating, being on this team as long as I've been here and not being able to contribute to the wins."

Cook (1-5) allowed four runs and eight hits for his first win since Sept. 8, 2010, against Cincinnati. He also went 2 for 3, scoring a run and driving in another.
More impressive to Rockies manager Jim Tracy was the right-hander's ability to escape the sixth inning with only one allowed despite an outfield misplay leading to Miguel Montero's leadoff triple.
"He is very well-grounded and I give him credit," Tracy said. "We put him in what was a 3-3 game and put him in a very tough spot. He did a tremendous job of getting out of that inning with just the one run."
Fowler finished 3 for 5, needing only a home run for the cycle, and scored twice. Ellis was 3 for 4 with two runs scored and a stolen base. Troy Tulowitzki also doubled and drove in a pair of runs for the Rockies, who have won three of their past four.
Geoff Blum hit his first home run and Willie Bloomquist added an RBI triple for the Diamondbacks, who have lost three of four.
Gerardo Parra gave the Diamondbacks a 4-3 lead in the sixth when he singled home Montero after the leadoff triple. But Colorado rallied in the top of the seventh against Daniel Hudson (10-6).
Fowler doubled, and Hudson hit Ellis and Todd Helton with pitches to load the bases. Hudson retired Tulowitzki on a run-scoring grounder to short to tie the game at 4. But Seth Smith followed with a sacrifice fly to center off reliever Joe Paterson to give the Rockies their first lead.
Colorado added two more runs in the eighth off Sam Demel. Eric Young Jr. drew a two-out walk and scored on a triple by Fowler high off the center-field wall. Ellis then lined a single to right, scoring Fowler to make it 7-4.
"We made it really tough on ourselves," Diamondbacks manager Kirk Gibson said. "We didn't make a couple of plays he [Hudson] had to throw more pitches, he didn't get a sac bunt down. Colorado did a good job of extending him. He spent a lot early."
Hudson allowed five runs on 10 hits in 6 1/3 innings with a walk and seven strikeouts.
"It was one of those things where I couldn't find it out of the stretch," Hudson said. "You have to be able to make an adjustment better than that. I couldn't get a strikeout when I needed to."
Blum's first home run since last Sept. 20, a span of 255 at-bats, and an RBI groundout by Hudson gave Arizona a 3-0 lead in the second.
Helton hit a sacrifice fly and Tulowitzki added an RBI double to cut Arizona's lead to 3-2 in the third, and the Rockies tied it on an RBI single by Cook in the fourth.
