Avalanche 1, Penguins 0: Jean-Sebastien Giguere turned aside 34 shots for his 38th career shutout as Colorado snapped host Pittsburgh's four-game winning streak.

Captain Gabriel Landeskog scored for the third consecutive game as the Avalanche (8-1-0) remained perfect in five road games and handed the Penguins their first defeat in six home contests. Giguere improved to 3-0-0 and posted his second shutout of the season by making 16 saves in the final 20 minutes.

Marc-Andre Fleury stopped 13 shots as he absorbed his first loss in eight games for the Penguins, which held Colorado without a shot for the first 13 1/2 minutes of the game and for nearly the first 12 minutes of the third period. Pittsburgh went 0-for-7 on the power play against the league's No. 4 penalty-killing unit.

Landeskog broke the scoreless deadlock at 5:26 of the second period, coming out of the penalty box and streaking down the right side before unleashing a wrist shot that hit a defender's stick and sailed past Fleury.

The Penguins dominated the first period, going on the power play three times in the first 12 minutes while keeping the Avalanche from registering a shot, but they were unable to muster many solid chances against Giguere. The 36-year-old netminder made his best stop with just over 7 1/2 minutes to play in the game, denying Chris Kunitz with a glove save.
