ATLANTA -- Chipper Jones hit a two-run homer, Jair Jurrjens earned his NL-leading 12th win and the surging Atlanta Braves beat slumping Colorado 9-1 on Wednesday night.
Dan Uggla added a two-run homer in the eighth and Jordan Schafer had four hits for the Braves, who have won eight of their past nine, including three straight over Colorado.
Jurrjens (12-3) allowed one run and five hits and two walks in six innings. He has allowed no more than one run in four straight starts, leaving his NL-leading ERA at 1.87.
The Braves scored three runs in the first off Aaron Cook (0-4) before Jones' homer in the third pushed the lead to 5-0.
The Rockies (41-46) have lost four straight and are five games under .500 for the first time this season.
Uggla had two hits, including his homer off Rafael Betancourt in the eighth. Uggla has hit homers in back-to-back games as he attempts to emerge from a season-long hitting slump.
Before the game, Jones said a cortisone shot in his right knee after Sunday's game did not provide much relief for the discomfort he has felt much of the season.
He found more pain in the first inning when he fouled a ball off his right ankle and immediately fell in the batter's box. Jones slowly got up and appeared to be favoring the ankle when he ran to first base on his ground out to second.
Jones' reward for remaining in the game came in the third when his fly ball barely cleared the left-field wall for his eighth homer.
Ian Stewart doubled and scored on Matt Pagnozzi's single in the fifth for Colorado's only run.
Cook struggled early in his sixth start after breaking a finger in spring training and missing the first two months of the season.
Schafer led off with a triple past Charlie Blackmon in center field. Alex Gonzalez drove in Schafer with a single to right before scoring on Brian McCann's double to center. With two outs, McCann scored on Eric Hinske's single for a 3-0 lead.
Jurrjens took a no-hitter into the seventh inning of his 4-0, one-hit shutout of Baltimore on Friday night. He also was strong early against the Rockies, recording 10 straight outs before giving up Jonathan Herrera's single with one out in the fourth. Herrera moved to third on Ty Wigginton's infield hit before Seth Smith ended the inning with a fly ball to left.
Scott Linebrink struck out Wigginton with the bases loaded to end the seventh.
Cook gave up 10 hits and seven runs in five-plus innings. He was pulled after giving up singles to Hinske and Uggla in the sixth.
Rex Brothers walked Nate McLouth to load the bases. Pinch-hitter Jason Heyward's double play grounder drove in Hinske before Schafer's single to center pushed the lead to 7-1.
