DENVER -- It wasn't easy, but the Colorado Avalanche remained unbeaten for new coach Patrick Roy.
The Avalanche needed an empty-netter from PA Parenteau, his second goal of the game, with 1:12 remaining to secure a 3-1 win against the Nashville Predators on Friday at Pepsi Center.
The Avalanche took a 2-0 lead on goals from Parenteau and Patrick Bordeleau, but the Predators cut the margin on half on a goal by Paul Gaustad at 14:10 of the second period just as a slashing penalty to Colorado's Steve Downie expired.
Parenteau opened the scoring at 18:50 of the first period. Jamie McGinn, who scored two goals in a 6-1 win Wednesday against the Anaheim Ducks, was being covered by Predators defenseman Seth Jones but managed to get off a good shot that goalie Pekka Rinne stopped.
Parenteau was near the right post when he poked in the rebound with linemate Nathan MacKinnon in front as Rinne was falling to the ice in a collision with teammate Mattias Ekholm.
The Avalanche were able to rush the puck up ice with ease after Gaustad and teammate Matt Hendricks collided deep in the offensive end.
The Avalanche fourth line of Cody McLeod, Marc-Andre Cliche and Bordeleau combined for the second goal at 7:54 of the second period.
McLeod worked along the boards behind the net to gain possession and pass to Cliche near the right-wing boards. Cliche fed Nate Guenin at the right point for a shot that 6-foot-6 Bordeleau deflected behind Rinne for his third goal in 48 career NHL games.
The Avalanche weren't able to convert after going on a power play a little less two minutes later when Predators captain Shea Weber was assessed a double-minor for roughing. Weber hit Matt Duchene before Downie checked Roman Josi in the corner. Gabriel Bourque and Weber responded by hitting Downie.
Josi left with an upper-body injury and didn't return.
Gaustad scored while driving down the slot. Mike Fisher passed the puck to Gaustad and fired the puck by Avalanche goalie Semyon Varlamov's glove.
Alex Tanguay nearly regained Colorado's two-goal lead during a delayed penalty. He skated through the goalmouth and took a backhanded shot Rinne stopped with his left skate.
Rinne rebounded from a poor performance Thursday when he gave up three first-period goals on six shots and was pulled in the Predators' 4-2 loss at the St. Louis Blues. He began Friday with an 11-3-1 career record against the Avalanche with a 2.03 goals-against average and .920 save percentage.
