St. Louis, MO (Sports Network) - Dion Phaneuf scored the game-winning goal in overtime to lift the Calgary Flames over the St. Louis Blues, 2-1, at Scottrade Center.

Jarome Iginla scored the other goal for the Flames, who were coming off a 3-2 overtime win against the Stars on Wednesday. Calgary defenseman Jay Bouwmeester played his 356th consecutive game, the longest active streak of any player. Miikka Kiprusoff turned aside 30-of-31 shots for the victors.

"I think overall it was probably our best road game of the year. We were suddenly more patient in the way we played. I thought our neutral zone play was much better," Flames head coach Brent Sutter said.

Lars Eller scored his first career goal in his NHL debut for the Blues, who were shut out in their previous two games. Chris Mason stopped 29-of-31 shots for St. Louis, which has lost four of its last five contests.

"I thought we played a lot better tonight. That's a really good hockey team over there," Mason said. "I thought we played them really strong. I think the biggest thing is that we played well and stuck with the system."

Phaneuf's slapper from the point made its way through a number of players in front before finding the back of the net at the 2:50 mark of the extra session.

Down 1-0, the Blues snapped a scoreless drought that lasted 171 minutes and 5 seconds. A Dustin Boyd tripping penalty put St. Louis on the power play at the 5:20 mark of the third. After winning a faceoff in the Flames' zone, Erik Johnson fired a slapshot on net. The disc deflected off Eller's arm and into the back of the net to tie things with 12:45 remaining.

The Flames drew first blood at the 3:34 mark of the first period. Olli Jokinen's perfect pass from center ice set up Iginla on a breakaway. Iginla fired a wrister that trickled through the pads of Mason. The disc slowly crossed past the goal line before Mason could find the puck.

A pair of Calgary hooking penalties, which were separated by 23 seconds, gave St. Louis a 5-on-3 power play in the second. The Blues failed to score on five shots during the power play.
