Slovakia's Marian Hossa scored 1:44 into overtime as the Chicago Blackhawks extended their record for the best start in NHL history by beating the Edmonton Oilers 3-2 on Monday.
Swedish forward Viktor Stalberg and Patrick Kane also scored for Chicago, who are riding a league record of 19 straight games with at least a point (16-0-3) to open the season.
The Anaheim Ducks held the previous record of 16 games to begin the 2006-07 season.
"The biggest thing is that we don't want to lose right now," Kane, of the US, said. "We want to keep this thing going. I'm telling you, after the second period guys weren't very happy that we were down a goal and we knew we wanted to come back and change that right away."
Canadian goaltender Ray Emery stopped 17 shots for Chicago, who have won six in a row and improved to 8-0-1 at home this season.
American Jeff Petry and Russian rookie forward Nail Yakupov scored goals for the Oilers, who began a nine-game road trip on Monday.
Nikolai Khabibulin stopped 31 of 34 shots in the loss.
Stalberg tied the game 2-2 early in the third period. Michal Rozsival threw the puck toward the crease for Stalberg, who stabbed at it and it slid under Khabibulin, of Russia.
In overtime, Hossa knocked in his own rebound to enable Chicago to extend the streak.
Edmonton were without forward Taylor Hall, who was serving the second of a two-game suspension.
