After the team’s exchanged misses, Tanguay’s shot over Jason Bacashihua’s glove gave Calgary the edge. Miikka Kiprusoff denied Doug Weight on a deke, giving Iginla the opportunity to clinch it. He whipped a shot into the corner over Bacashihua’s blocker.
Kristian Huselius had a goal and three assists for Calgary. David Moss, Daymond Langkow, and Dion Phaneuf also scored for the eighth-place Flames, who pulled within one point of Minnesota, Dallas, and San Jose in the Western Conference playoff race.
The Blues outshot the Flames 6-0 in overtime but couldn’t beat Kiprusoff, who was at his best when killing a power play.
The Flames took a 4-2 lead in the third period on Phaneuf’s power-play goal at 3:16 and Langkow’s goal at 6:44. But the Blues responded, making it 4-3 just 22 seconds later when Cajanek scored his 11th goal. Brad Boyes earned his third assist of the night, giving the center eight points during a five-game scoring streak.
St. Louis pulled even at 10:06 on a great play by rookie David Backes. After crossing the Flames blue line and drawing two defenders toward him, Backes neatly dished the puck off to Stempniak darting toward the Calgary net. The Blues’ leading goal scorer jammed in his second of the night and 23rd of the season.
Moss lifted Calgary into a 1-1 tie at 2:28 of the second period.
Bacashihua made his first start since Dec. 13 for St. Louis and made some sensational saves in finishing the night with 30 saves.
Kiprusoff finished with 29 stops.
