Max Pacioretty scored the winner midway through the second period and Carey Price stopped 29 shots as the upstart Montreal Canadiens defeated Boston 3-1 in Game 7 on Wednesday to oust the league-leading Bruins from the playoffs.
The Canadiens started fast and then stymied the Bruins, winners of the Presidents' Trophy for the best regular-season record, to advance to the Eastern Conference final against the New York Rangers.
Dale Weise and Daniel Briere, with a late power-play goal, also scored for Montreal.
Jarome Iginla's goal, which cut the Canadiens' lead to 2-1 with 2:08 remaining in the second, set the scene for a dramatic third period. The black and gold faithful hoped for yet another Bruins comeback.
They almost got their wish early in the third when Iginla, pouncing on a rare Price rebound, hit the post. Boston came on but the Canadiens held fast and Price, improving his record in elimination games in 2014 to 5-0 including the Olympics, was rock-solid with a disciplined team defending in front of him.
The late Boston surge was not helped by a Johnny Boychuk penalty for interference with 4:31 remaining. Montreal scored on the ensuing power play when Briere's centring pass bounced in off Zdeno Chara's skate at 18:07 to pad the lead to 3-1.
Montreal killed off a late interference penalty to Andrei Markov -- and a 6-on-4 Boston opportunity -- to seal the win.
The Bruins outshot Montreal 30-18.
The game drew two sellouts: 17,565 at TD Garden and some 21,000 at the Bell Centre, where fans paid $10 to watch the game on the video scoreboard with proceeds going to charity.
