Daniel Carcillo scored the tiebreaking goal with 49.3 seconds left in regulation and the Chicago Blackhawks won their 11th consecutive game, beating the Colorado Avalanche 3-2 on Wednesday night to extend the best start in NHL history.
Jonathan Toews and Andrew Shaw also scored for Chicago (21-0-3), which reached the halfway point of a lockout-shortened season without losing in regulation. The remarkable Blackhawks have earned at least one point in their first 24 games, stretching their NHL record.
Dating back to last year's regular season, the streak is 30 games.
The Blackhawks broke the previous team record for consecutive wins with their 10th in a row Tuesday night, 5-3 over Minnesota.
Chicago's overall points streak is the second-longest during one season in NHL history. The 1979-80 Philadelphia Flyers set the league record at 35 games with a 25-0-10 run.
Carcillo knocked in a rebound with a backhand shot, his first goal of the season, after Semyon Varlamov made two in-close stops on Viktor Stalberg during a scrum in the crease.
Toews scored a highlight-reel, short-handed goal early in the third period, beating two Avalanche players to tie the score at 2. Chicago trailed after two periods for only the fourth time this season.
John Mitchell and Matt Duchene scored for Colorado, which has lost six of seven.
Ray Emery made 20 saves for the Blackhawks to improve to 10-0. Varlamov finished with 29 stops.
Blackhawks forward Marian Hossa sat out with an upper-body injury. Shaw left the game late in the second period and teammate Patrick Sharp left midway through the third.
Shaw's power-play goal on a deflection opened the scoring midway through the first. Shaw was parked in front of the crease, and Brent Seabrook's drive from the right point ticked in off the shaft of Shaw's stick.
Mitchell tied it with 1:40 left in the first, exploiting a rare Chicago coverage mix-up. Mitchell skated alone to the right side of the net, took a quick pass across the crease from Chuck Kobasew and lifted a backhand past Emery.
Varlamov stopped Patrick Kane on a 2-on-1 break and Carcillo on a point-blank chance early in the second.
Kobasew missed on a breakaway at 6:11 of the second moments after he jumped back on the ice from the penalty box.
Duchene put Colorado ahead 2-1 with 6:43 left in the second, moments after Varlamov made a point-blank pad save on Sharp.
Duchene streaked down the left side, slipped past Seabrook and took a pass from P.A. Parenteau. Duchene fired from a sharp angle near the goal line, but the puck struck Emery and slipped in under his right arm.
Toews scored at 2:19 of the third to tie it 2-all. He moved down the right wing, then cut to the net around Ryan O'Reilly. Toews skated across the crease — behind both O'Reilly and Jamie McGinn — and banked in a shot off the left post.
O'Reilly and McGinn are forwards who got caught as the two men back during the Colorado power play.
Carcillo's game-winner was his first goal since returning from a knee injury on Feb. 22.
