MONTREAL -- Max Pacioretty's slump is over.
The big left wing had a goal and an assist in the second period and Carey Price made 26 saves and the Montreal Canadiens blanked the Boston Bruins 4-0 on Monday night to force Game 7 in their Eastern Conference semifinal series.
The series is tied 3-3 going into Game 7 on Wednesday night in Boston.
Pacioretty, who had only one assist in the first five games, scored and set up Thomas Vanek's goal in the second period. Lars Eller scored in the first for Montreal and Vanek added his second of the game into an empty net with 3:56 left.
"I was just waiting for my time to pitch in offensively," Pacioretty said.
"Obviously you wanted it to happen more often in the playoffs, but it's two do-or-die games where I've scored a goal so I feel confident that I'm helping the team.
"You want to feel you're helping the team win and I think I did that tonight."
Rookie Nathan Beaulieu, the Canadiens' 2011 first-round draft pick who was given a surprise start by coach Michel Therrien, picked up an assist in his first NHL playoff game and was plus-2.
"I never played at a pace like that before," the 21-year-old said. "It was incredible. It was good to get the first period under my belt and I felt I settled down after that."
The Canadiens repeated the scenario of their 2011 first-round series against the Bruins, winning at home to force a Game 7. That year, they lost Game 7 in overtime. The Bruins went on to win the Stanley Cup.
Boston coach Claude Julien felt his team played well, but didn't finish its chances.
"The second goal probably hurt us the most because we were spending a lot of time in their end and we had some great chances to tie the game, but that kind of turned the tide around," Julien said. "I didn't like the way they got their goals tonight.
"But we had more lines going than we've had this whole series. We spent a lot of time in the offensive zone, but if you hit posts and miss open nets. ... You've got to bury those chances. Tonight they came back to haunt us."
Montreal got off to a strong start after a rousing pregame show and the teams played at a ferocious pace through the first two periods.
Despite having the best of the play in the opening 20 minutes, the Canadiens needed an unusual play for the only goal.
The second period was marked by a remarkable 5:11 stretch without a whistle in which the Bruins bottled the Canadiens in their end for minutes at a time, only to see Milan Lucic miss their best scoring chance from the edge of the crease.
Pacioretty kept a puck alive with his feet amid a crowd in front of Rask during a power play and saw the puck slide to Vanek for a shot into an open side at 17:39.
The Bruins came close at 11:05 of the third when a Chara shot went off Price and dropped behind him. But with Jarome Iginla digging in the crease, David Desharnais was on his knees to stop the puck with his stick just as it had almost crossed the goal line.
The no-goal call stood up to video review.
