Rene Bourque scored twice and Jarome Iginla connected once in the third period for the Flames, who fell short in trying to come back from a 4-1 deficit. Alex Tanguay added a goal and an assist for Calgary, which lost in regulation for only the second time in its last eight games.

Tanguay stretched his points streak to six games and has three goals and seven assists during the run.
Toews opened the scoring 6:46 in, capping a crisp, cross-ice passing play with linemates Patrick Sharp and Patrick Kane. Toews was wide open at the right side of the crease and fired in a shot before Kiprusoff could slide across.
Tanguay tied it midway through the first on a power play, beating Crawford with a high screened shot from the left circle.
Frolik made it 2-1 with 1:35 left in the period when he drove to the net and scored his first goal since Dec. 17 with Florida. It also was his first point in 10 games since being acquired from the Panthers in a trade Feb. 9.

Iginla ripped in a screened shot from the crease at 8:44 to make it 4-3 Just over two minutes later, however, Bolland connected from the right circle to make it 5-3. Bourque scored his second goal, on a long rebound, with 3:56 left to trim it to 5-4.
