DENVER (AP)Artturi Lehkonen and Valeri Nichushkin each scored two power-play goals, Mikko Rantanen had four assists and the fast-skating Colorado Avalanche began their Stanley Cup title defense with a 5-2 victory over the Chicago Blackhawks on Wednesday night.

Shortly after raising their newest banner to the rafters, the Avalanche went to work. Andrew Cogliano scored Colorado’s first goal of the season, the only goal in the game that wasn’t on the power play. Nathan MacKinnon, fresh off a new lucrative contract, contributed two assists, while new goaltender Alexandar Georgiev stopped 15 shots.

Jonathan Toews and Max Domi had goals as Luke Richardson made his coaching debut for the Blackhawks. Petr Mrazek finished with 30 saves against an Avalanche team that won the title last season by dethroning Tampa Bay in six games.

The crowd was revved up well before the puck even dropped.

The appetizer: A highlight video of Colorado’s run to the franchise’s third Stanley Cup title. Then, some music as Mark Hoppus of the Blink-182 led a sing-along of the band’s tune ”All The Small Things,” which became an anthem for the Avalanche.

There also was captain Gabriel Landeskog hoisting the Cup and skating around with the trophy (he missed the game with a lower-body injury). Of course, there were plenty of on-ice pictures, including a memorable shot of the team with Blackhawks defenseman Jack Johnson joining in. Johnson was with Colorado last season.

WASHINGTON (AP) – David Pastrnak had a goal and three assists, captain Patrice Bergeron scored and Boston beat Washington in the season opener for both teams.

He sought and received help for alcohol abuse, spent time as an assistant in St. Louis and is getting another chance with Boston.

Linus Ullmark made 33 saves for Boston. Hampus Lindholm scored an empty-netter with 1:05 left.
