DENVER — Even Atlanta closer Craig Kimbrel blows saves from time to time.
Kimbrel was one out away from earning his ninth save of the season before he gave up two runs in the ninth inning.
The Braves went on to lose 6-5 in 12 innings to the Rockies, denying Atlanta of a three-game sweep.
"Closer is a tough situation and saves are tough to come by," Atlanta manager Fredi Gonzalez said. "He is human and there are days when they won't convert them.'
"Today, he didn't convert it," Gonzalez said.
Kimbrel had converted all eight saves this season and the last 10 chances to preserve games a year ago when he was 42-for-45. He last blew a save on Aug. 31, 2012 against Philadelphia.
"I got hurt with some pitches," Kimbrel said. "I didn't execute."
Wilin Rosario scored from second on Yorvit Torrealba's single to left and the Colorado Rockies rallied to beat the Braves on Wednesday.
The Rockies rallied off Kimbrel in the ninth to deny Tim Hudson his 200th career win. Dexter Fowler hit a tying double off the wall in left with two outs. Jonathan Herrera hit a one-out double and pinch-hitter Troy Tulowitzki followed with a single before Eric Young Jr. struck out.
"I tried to elevate it to Herrera, but I didn't get it up enough," Kimbrel said. "Tulo came up and hit a good curveball and then Fowler hit the ball well.
Fowler's drive took leftfielder Justin Upton back to the wall. The ball eluded Upton and carried back toward thr infield.
"I misread it," Justin Upton said. "It was hit hard and I retreated, but not far enough back to catch it."
Rosario led off the 12th with a double to left off Luis Ayala (1-1). After Cuddyer was intentionally walked, Belisle, who had to bat with no one else left on the bench, struck out on a bunt attempt.
Torrealba ripped a single to left, and Justin Upton's throw home was wide as Rosario slid in with the winning run.
Hudson looked set for his milestone win after he allowed three runs on six hits in six innings, struck out three and helped out with an RBI single in the fourth.
It was 48 degrees at first pitch, more than double Tuesday's 23-degree start to the doubleheader. Sunshine bathed Coors Field in the final game of a 10-game homestand that included three postponements due to snow.
Right-hander Tyler Chatwood was recalled from Triple-A Colorado Springs before the game and made his first major league start of the season. He allowed five runs, four earned, on nine hits and struck out three in six innings.
He left trailing 5-3 after Atlanta scored twice in the fourth on Herrera's throwing error and Jordan Schafer's RBI single.
The Rockies took a 2-0 lead when Cuddyer and Rutledge homered off Hudson on consecutive at-bats. It was the first time this season Colorado has hit back-to-back home runs this season.
Atlanta rallied to take the lead in the fourth. Freddie Freeman's double to right scored Upton from first, Juan Francisco singled to center to drive in Freeman and Hudson's single made it 3-2.
Chatwood answered in the bottom of the inning with an RBI single that bounced off home plate, allowing Chris Nelson to score from third.
"There will be no residue the next time he goes out there," Gonalez said of Kimbrell. "He will be fine and he will take the ball the next time."
