Denver, CO (Sports Network) - Aaron Cook pitched a complete game for the first shut out of his career, and Matt Holliday was the only Rockie with two hits as Colorado beat San Diego, 4-0, in the middle of a three-game set from Coors Field.

Cook (11-5) yielded just five hits and struck out four batters for the Rockies, who saw their eight-game losing streak come to a halt. Garrett Atkins and Willy Taveras each had a hit and an RBI in the win.

Josh Banks (2-3) took the loss as he gave up four runs and six hits in five innings.

"It wasn't just his location," Padres catcher Michael Barrett said of Cook. "It was the velocity, the movement and the relentlessness in the strike zone."

The Rockies jumped on top, 4-0, in the fifth inning. Troy Tulowitzki led the frame off with a double and moved to third on Cook's sacrifice bunt. Taveras singled to right, plating the runner, and stole second base. Todd Helton worked a walk and Taveras took third.

"I was looking for a pitch so I could put the ball in play," Taveras said. "He (Banks) left a pitch down and away and I hit the ball to right field."

Holliday was issued a free pass before Brad Hawpe grounded into what looked like a double play. However, Khalil Greene recorded the out at second, but botched the throw to first, allowing Helton and Taveras to score.

Atkins kept it going with a line drive RBI single to right, and the Rockies held a 4-0 lead.

Cook got Jody Gerut to ground to second for the first out in the ninth. Edgar Gonzalez chased the third strike for the second out and Brian Giles flied out to deep center to seal the deal.
