Rookie defenceman Ryan Wilson scored his first NHL goal and added an assist to lead the Colorado Avalanche to a 3-2 win over the Calgary Flames on Tuesday night.

Milan Hejduk scored the game-winning goal on a power play for the Avalanche (13-5-3), who moved three points ahead of the Flames (12-5-2) in the battle for top spot in the Northwest Division. Cody McLeod also scored, while Paul Stastny chipped in with a pair of assists.

Calgary captain Jarome Iginla continued his hot streak with his 12th goal of the season, and eighth in his past seven games. Rene Bourque also scored for the Flames, who had earned points in six straight games prior to Tuesday's setback.

Avalanche goaltender Craig Anderson made 34 saves on 36 shots, none bigger than a pad save on a point-blank shot by Olli Jokinen with three minutes left in the third period.

Calgary goalie Miikka Kiprusoff made 21 saves as he lost in regulation for the first time in November.

Aided by an early power play, the Flames fired the first six shots of the game on net but couldn't get one past Anderson.

The Avalanche then bounced back to fire seven straight shots at Kiprusoff, scoring on one. After Kiprusoff made two straight pad saves on shots by Colorado forward Wojtek Wolski, Wilson crept in off the point and picked up a loose puck in the slot before backhanding a shot into the Calgary net.

At 11:39 mark of the second period, Curtis Glencross spotted Iginla wide open in the high slot and fed him a perfect pass that the Calgary captain one-timed into the top corner past Anderson.

Less than six minutes later, with the Avalanche enjoying a man advantage, Bourque snapped a shot into the top corner over Anderson's outstretched glove to put Calgary up 2-1.

Prior to the play, Avalanche defenceman Kyle Quincy broke his stick when he took a slap shot from the point. Dustin Boyd alertly picked up the puck and sent it to Jay Bouwmeester, who feathered a great cross-ice pass to Bourque on the left wing in the Colorado zone.

Only 42 seconds after Bourque's goal, McLeod converted a feed from Stastny past Kiprusoff to tie the game at 2-2. Wilson also recorded an assist on the play to double his point production to four points on the season.

The scoring outburst continued 66 seconds later when Hejduk attempted to hit Darcy Tucker with a cross-crease pass while the Avs were on another power play. The puck deflected off of Bouwmeester's skate instead and behind Kiprusoff to give Hejduk his eighth goal of the season.
