Giguere made 38 saves to help the Anaheim Ducks beat Calgary 4-1 on Thursday night.

Kunitz gave Anaheim a 2-1 lead with 41 seconds left in the first period.
Getzlaf, showcasing the playmaking ability that made him a fan favorite in his four seasons with the Western Hockey League's Calgary Hitmen, carried the puck into the Flames' zone, made a slick fake on defenseman Dion Phaneuf, then slid the puck across to Kunitz left uncovered in the slot for an easy tap-in.
"I just went to the front of the net and he made a nice backhand pass and I had a wide-open net," said Kunitz. [Getzlaf] has world-class hands, a great shot, he's big, and he's physical. We call him the franchise because that's what he is. He goes out there and plays with his heart on his sleeve."
Getzlaf, the 22-year-old star who signed a $26.5 million, five-year contract extension last week, has points in nine of the past 10 games, amassing six goals and eight assists over that span.
"He's an elite level player," Anaheim coach Randy Carlyle said. "Not too many people can carry the puck into the offensive zone and make those kinds of moves. He's a special player."
With the victory, the Ducks improved to 8-3-3 in their last 14 games, and moved within two points of first-place Dallas in the tight Pacific Division.
Calgary has lost four of its last five games.

Iginla played in his 804th career game, moving him past Hall of Fame defenseman Al MacInnis into first place on the Flames' career list.
