Johnny Estrada hit a two-run double as part of a six-run first Tuesday night that sparked the Braves to a 9-5 victory over the worst team in the majors.
Estrada, Ryan Langerhans, Raul Mondesi and pitcher John Thomson all had two-out RBI in the first. The Braves scored all nine of their runs with two outs and have now scored 79 of their 164 runs this season -- a whopping 48 percent -- with two gone.
"Tonight, we got them when we needed them," said Marcus Giles, who had four hits and an RBI. "You aren't going to come through every night, but I think we are going to do it more often than not."
Andruw Jones had three hits and an RBI for Atlanta, which has won six of seven.
The Rockies, meanwhile, failed in their third attempt this year to string together three straight wins. They fell to 8-22, putting them on pace to lose 118, which would be just two short of the modern-day record of 120 set by the 1962 New York Mets.
Much of the blame for this one falls on starter Jason Jennings (1-4), who has allowed 12 runs in the first innings of his seven starts this season.
"It was basically just embarrassing the first inning," Jennings said. "The way I was pitching was not acceptable."
Jennings got ahead in the count on Chipper Jones in the first but walked him, then blew an 0-2 advantage and walked Andruw Jones to load the bases.
Estrada, who finished with three hits, followed by hitting the ball hard to right for a 2-0 lead. Langerhans kept things going with a two-run single, then Mondesi hit an RBI double that left fielder Cory Sullivan misjudged in the swirling wind. Thomson followed with a hard-hit double to the left-field fence to make it 6-0.
"You've got two outs and an 0-2 count," Rockies manager Clint Hurdle said. "Six runs later, the inning is over."
Jennings faced 11 batters in the first, walked three and threw 48 pitches. He allowed seven runs and nine hits in four innings.
Thomson, one of Colorado's first draft picks back in 1993, only made it through 4 2/3 innings.
The win went to Jorge Sosa (2-0), who entered with an 8-5 lead and was rescued by Langerhans, who made a diving catch in left off a well-hit ball by Clint Barmes with runners on first and second. Langerhans also made a pair of nice catches to take hits away from Aaron Miles in the eighth and Brad Hawpe in the ninth.
"If they were going to give a save tonight, they should give it to the left fielder," Hurdle said. "That kid can go get the ball."
Colorado got 3 2/3 innings of shutout relief from its bullpen Monday in a 7-6 win over the Braves and was forced to burn its bullpen again. Marcos Carvajal, David Cortes and Jay Witasick all worked -- on the day before the Rockies give a spot start to Byung-Hyun Kim, who will take the place of hurting Joe Kennedy in the rotation.
Preston Wilson had three hits, including a double as part of Colorado's three-run fifth inning. Pinch-hitter Garrett Atkins hit an RBI single to pull the Rockies within 8-5 in the fifth and chase Thomson.
After Sosa worked an inning and allowed one hit, four Braves relievers combined to hold Colorado scoreless over the final 3 1/3 innings. In two games against the Rockies, the Atlanta bullpen has allowed four hits and no runs over 8 2/3 innings.
"I think guys are being effective with their location and making the right pitches at the right times," said closer Danny Kolb, who worked the ninth in a non-save situation.
Injured Rockies reliever Bobby Seay (pectoral muscle) was scheduled to throw in the bullpen Wednesday and Saturday. ... Rockies catcher J.D. Closser fell to 0-for-14 on stolen-base attempts this season when Rafael Furcal stole second in the seventh. ... Braves manager Bobby Cox said Adam LaRoche will likely not play Wednesday because of a slight injury to his left leg. ... The Braves placed RHP Kevin Gryboski (viral infection) on the disabled list, and recalled pitcher Frank Brooks from Richmond.
