DENVER - The Chicago Blackhawks' record streak ended with a thud.
Matt Duchene and John Mitchell scored 33 seconds apart in Colorado's four-goal second period and the Avalanche ended Chicago's historic run with a 6-2 win on Friday night.
Chicago started the season with at least a point in 24 straight games, an NHL record. The Blackhawks earned a point 30 straight games over two seasons, bested only by the 1979-80 Philadelphia Flyers, who did it in 35 straight games.
Now, those marks are in the books after last-place Colorado did what no other NHL team could this year. The Blackhawks' last regular-season regulation loss was 6-1 to Nashville on March 25, 2012.
Duchene added three assists and P.A. Parenteau and Paul Stastny had a goal and two assists each. Ryan O'Reilly and Jamie McGinn also scored for Colorado, which avenged a 3-2 overtime loss in Chicago on Wednesday.
Jonathan Toews and Bryan Bickell scored for the Blackhawks, who lost in regulation for the first time in nearly a year. They also had their franchise-record 11-game winning streak snapped.
Early, it looked like they would make it 25 straight when Marian Hossa, back after missing Wednesday's game with an upper-body injury, fed Toews for his 11th goal of the season 5:44 into the game.
Colorado tied it 11 minutes later when Stastny scored his seventh of the season to start the Avalanche onslaught. Duchene gave Colorado the lead with his ninth goal 4:16 into the second, Mitchell beat Corey Crawford at 4:49 and the rout was on.
O'Reilly got his first goal of the year four seconds into a power play midway through the second and McGinn ended the rally with his fourth goal at 13:58.
Crawford allowed five goals on 19 shots before being replaced by Ray Emery to start the third.
Bickell made it a 5-2 game with goal midway through the third period and Parenteau scored with 4:14 left.
Semyon Varlamov finished with 30 saves for Colorado.
NOTES: Blackhawks forward Patrick Sharp was scratched with an upper-body injury. Forward Michael Frolik (illness) was back in the lineup after missing two games. ... Johnson returned after missing 11 games with a head injury. He took the place of rookie Tyson Barrie. ... Friday was the nine-year anniversary of Todd Bertuzzi's hit on Colorado's Steve Moore. Bertuzzi, then with Vancouver, hit Moore from behind and drove his face into the ice. Moore suffered three fractured vertebrae, a concussion and some brain damage, which ended his career. Bertuzzi was suspended for 17 months, but a majority of that time was during the 2004-05 lockout. Bertuzzi returned to the league and is now playing for the Detroit Red Wings.
