Avalanche 1, Penguins 0
Colorado captain Gabriel Landeskog, fresh out of the penalty box, scored the game-winner at 5:26 of the second period.
Landeskog corralled a loose puck near the top of the right faceoff circle, used Penguins defenseman Brooks Orpik as a screen and wristed the puck through Orpik's legs and past Pittsburgh goaltender Marc-Andre Fleury for his third goal of the season.
Goalie Jean-Sebastien Giguere stopped all 34 shots he faced for the Avalanche (8-1-0).
The Penguins (7-2-0) lost despite holding the opponent to a season-low shot total. Pittsburgh went 0-for-7 with the power play and failed to take advantage of a career-high seven shots from Sidney Crosby.
Fleury made 13 saves while suffering his first loss of the season.

Niemi blanked Detroit for the third time in his career.
All three Detroit skaters - Pavel Datsyuk, Daniel Alfredsson and Todd Bertuzzi - were unsuccessful in the shootout. San Jose's Patrick Marleau had his attempt stopped by Howard.
