Although the game-winner was scored at even strength, it came just as a penalty expired on San Jose defenseman Scott Hannan. Hannan was called for hooking All-Star Paul Kariya with 27 seconds left in regulation.
Anaheim took advantage of the NHL's worst penalty-killing unit and spent most of the extra period in the Sharks' zone. They continued their record-setting week by picking up their 37th win and moving one point ahead of idle Minnesota into sixth place in the NHL Western Conference.
Seconds after he missed another chance to win it, Havelid took a cross-ice pass from Adam Oates. Using screens set by Kariya and Steve Rucchin, his blast from the point sailed over goaltender Evgeni Nabokov for his 10th goal.
The Ducks trailed, 2-0, midway through the second period before Petr Sykora scored twice in a 3:35 span. He leads the team with 32 goals and has seven in as many games.
