CHICAGO — Corey Crawford threw his gloves off and ditched his helmet as the Chicago Blackhawks poured onto the ice and swarmed the goaltender at one end of the frenzied United Center.

And just like that, the celebration was on. The marquee at Wrigley Field had a congratulatory message for the Stanley Cup champions, and there were fireworks and honking horns all over Chicago.

Call it a Windy City party 77 years in the making.

Duncan Keith scored in the second period and led a dominant defense that shut down Tampa Bay’s high-scoring attack, and the Blackhawks beat the Lightning 2-0 in Game 6 on Monday for their third NHL title in the past six seasons.

Patrick Kane had a goal and an assist, helping the Blackhawks clinch the Cup on home ice for the first time since 1938. Crawford, who was pulled from Chicago’s first-round series against Nashville, had 25 saves in his fifth career playoff shutout.

NHL Commissioner Gary Bettman called the Blackhawks a dynasty, and the delirious crowd of 22,424 agreed wholeheartedly.

“We won it for each other, for the city,” captain Jonathan Toews said. “In so many ways, winning a championship like this in our home city, I think it really transcends the sport. Everyone wants to be a part of it. It’s amazing.”

Keith was a unanimous selection for the Conn Smythe Trophy for playoff MVP after he finished with 21 points while playing more than 715 minutes during a grueling postseason. It was the sixth NHL title for the franchise.

“It feels so great. You want to keep being a part of these things,” Keith said. “You don’t get these awards without being on great teams with great players and like I said, I’m just proud to be a part of this group of guys who cares so much and do whatever it takes.”

It was an appropriate conclusion to a series full of near misses and close calls that had fans in Chicago and Tampa Bay on the edge of their seats for almost two weeks. It was only the second final to begin with five one-goal games, and no team enjoyed a two-goal advantage until Kane buried a perfect pass from Brad Richards at 14:46 of the third.

It was Kane’s first goal of the final, and it prompted more chants of “We want the Cup! We want the Cup!” from the fans.

“Just wanted to play my best game and control the puck as much as possible and try to step up for my team,” Kane said.

Ben Bishop kept the Lightning in the game with 30 saves.
