DENVER (AP) -- Chris Carpenter kept Colorado at bay long enough for St. Louis to finally get to Jason Jennings.

Elias Says ...

The Cardinals beat the Rockies 1-0 in Colorado. It was the 10th shutout in 46 games in Colorado this season (22 percent). From 1993-2005 there were only 38 shutouts in 1020 games played in Denver (4 percent). The game was only the fourth 1-0 game played in Colorado, and only the second in which the only run scored via a homer. Ryan Howard and the Phillies did it earlier this season. • For more Elias Says, click here.

Albert Pujols hit his 33rd homer, Carpenter scattered seven hits over 7 1/3 innings and the St. Louis Cardinals beat Colorado 1-0 Tuesday night to hand Jennings the first complete-game loss for a Rockies pitcher at home in franchise history.

"Guts. A lot of guts on both sides," Cardinals manager Tony La Russa said.

Pujols hit a 1-1 pitch from Jennings (6-9) into the right-field stands in the sixth. That was all the Cardinals could manage against Jennings, who allowed four hits and two walks.

"It's a changeup outside and four inches off the ground," Jennings said of the pitch to Pujols. "Not many people can hit that out."

Carpenter (10-4) repeatedly worked out of trouble to put St. Louis in position to win. He allowed runners to reach third base in each of the first three innings and retired the side in order just twice.

"I battled tonight, no question about it, but you are going to have those nights," Carpenter said. "I'll battle every night if I go 7 1/3 and not give up any runs; especially against a lineup like this. So it was a nice night."

Carpenter struck out four and walked three, one intentionally. He was pulled in the bottom of the eighth after giving up a one-out single to Matt Holliday, but reliever Randy Flores got Todd Helton to fly out to center and Brad Hawpe struck out swinging.

Jason Isringhausen pitched the ninth for his 28th save.

It was the eighth time this season the Rockies have scored one or no runs in one of Jennings' starts.

Jamey Carroll led off the bottom of the first with a double and took third on Clint Barmes' sacrifice bunt, but third baseman Scott Rolen threw him out at the plate when he tried to score on Garrett Atkins' bouncer to third.

The Rockies ran themselves out of the inning again in the fourth when Choo Freeman struck out on a 3-2 pitch and Brad Hawpe, who had singled, was thrown out at second on a botched hit-and-run play.

Rolen stopped the Rockies again with one on and two out in the fifth, stretching to his right to spear a grounder by Atkins, then firing from his knees to throw him out.

"That play he made was huge," La Russa said. "As it turned out, it changed the complexion of the game."

The Cardinals threatened in the first when David Eckstein and So Taguchi hit consecutive singles, but Pujols lined out to shortstop and Juan Encarnacion hit into a double play to end the inning.

Jennings settled in after that, giving up a walk in the second and then retiring 12 consecutive batters before Pujols' homer with two out in the sixth.
