CALGARY, Alberta -- The Calgary Flames continued their recent mastery of their provincial rival.
Calgary is playing its best hockey of the season. A 6-1-1 run has the Flames within one point of the Oilers in the Western Conference and just two points back of a playoff spot.
"Our whole game as a group is getting better," said Iginla, who leads the team with 11 goals.
"Our confidence is growing, we're moving the puck better, we've got more puck possession, and we're skating better. And our goaltending's been outstanding all season."
All three of the Flames' wins against Edmonton this season have come with the Oilers on the second of back-to-back games, a situation Oilers coach Tom Renney expressed his frustrations about after the game.
"I'd like that opportunity, I'd like to be able to play Calgary three times on the back end of a back-to-back and talk about intensity and jump and that kind of stuff," Renney said.
The Flames have also been unbeatable against the Oilers at home, with 10 consecutive wins at the Saddledome.
"I don't think there's a mental block or anything like that," Renney said. "I think we're closer to beating them than we believe we are."
Tom Kostopoulos' power-play goal was the winner for Calgary (14-13-2), which begins a difficult stretch with 11 of its next 13 games on the road.
Edmonton (14-13-3), winners of just two of its past eight, are off for the next four days before starting a short two-game road trip in Phoenix on Thursday.
The game was scoreless for the first half of the game until the Flames put out their fourth line for the final seconds of a power play and a faceoff deep in the Edmonton end.
"We knew they only had four men for 5 seconds so we wanted to set up a quick shot," Kostopoulos said. "The clean win off the faceoff was huge by Stajan and Smitty just having the presence of mind to put it at the net quick so maybe we could get a 2-on-1 in front and the puck was just lying there."
The goal came with Edmonton's Sam Gagner in the penalty box for a slash on Kostopoulos that prematurely ended an Oilers' 4-minute power play.
Calgary went in front 2-0 with 16 seconds left in the second.
With the teams skating 4 on 4 and Calgary on the attack, Iginla worked himself free in the high slot, took a pass from Brendan Morrison and sent a one-timer into the top corner.
Kiprusoff earned his second shutout of the season and 42nd of his career.
The most dangerous chance Kiprusoff faced was the result of his own misplay. Late in the first period, Kiprusoff mishandled a harmless looking dump-in and ended up kicking the puck right onto the stick of Ryan Jones in front of the net.
Jones let a quick shot go, but Kiprusoff threw out his left arm and grabbed the 20-footer with his glove.
"I don't know what I was doing, I didn't read it right," Kiprusoff said. "I just tried to kick it and tape-to-tape, so pretty lucky save there. It was a good feeling I was able to stop that because that was my mistake."
Nugent-Hopkins and Eberle entered the night with eight points each during six-game points streaks. Gagner had six points in his past four games.
"We're disappointed, we took a lot of penalties," Oilers defenseman Tom Gilbert said. "It's frustrating especially since it's a divisional team. They're a high-pressure team and we weren't moving the puck as well as we have been."

Edmonton D Andy Sutton served the second game of an eight-game suspension, which was handed down by the NHL prior to the game for his hit Wednesday night on Carolina's Alex Ponikarovsky. ...
