MONTREAL – Max Pacioretty’s slump is over.

The big left wing had a goal and an assist in the second period, Carey Price made 26 saves and the Montreal Canadiens blanked the Boston Bruins 4-0 on Monday to force a deciding Game 7 in their Eastern Conference semifinal series.

Game 7 is Wednesday in Boston.

Pacioretty, who had one point 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.

“I was just waiting for my time to pitch in offensively,” Pacioretty said.

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 playoff game and was plus-2.

“I never played at a pace like that before,” the 21-year-old said. “It was incredible.”

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.”

Ducks beat Kings, lead series 3-2

ANAHEIM, Calif. – Devante Smith-Pelly scored two goals 1:23 apart in the second period, and the Anaheim Ducks beat the Los Angeles Kings 4-3 to take a 3-2 lead in their West semifinal series.

Rookie John Gibson, 20, made 39 saves in his second career playoff start as the Ducks defeated the Kings for the third game in a row.

“I’m just trying to take it all in and win some hockey games,” Gibson said.

Nick Bonino and Jakob Silfverberg also scored for the Ducks, who jumped to a three-goal lead in the second period and earned the first home victory by either team in the series.

Marian Gaborik scored twice for the Kings, who host Game 6 Wednesday.
