Montreal - Michael Cammalleri scored his second goal of the game midway through the second period and Jaroslav Spacek netted the go-ahead tally 2:30 later for the Montreal Canadiens, who forced a Game 7 in the Eastern Conference semifinals with a 4-3 victory over the Pittsburgh Penguins on Monday night.

Maxim Lapierre also scored 11:03 into the third to give Montreal a 4-2 lead.

Bill Guerin deflected Sergei Gonchar's slap shot from the right point past Jaroslav Halak with 1:24 remaining to draw Pittsburgh within one. But the Canadiens held on to set up Game 7 in Pittsburgh on Wednesday.

Halak stopped 34 shots for the eighth-seeded Canadiens, who came back to beat Washington in the first round after falling into a 3-1 series hole against the Presidents' Trophy-winning Capitals.

Pittsburgh captain Sidney Crosby scored his first goal in seven games in the first period. Crosby earned an assist for his 19th point in 12 games when Kris Letang scored for a second game in a row early in the second.

That made it 2-1 for the Penguins, who had closed out five straight playoff series with a road win.

Cammalleri, who opened the scoring 1:13 in, drew the Canadiens even 10:45 into the middle period when he put a backhand past goalie Marc-Andre Fleury from the slot for his second of the game. He has 11 goals in 13 games.

Spacek, who returned to the lineup after missing nine games with a virus, drove a slap shot from the point past Fleury at 13:15 to touch off a thunderous ovation from the crowd. Fleury made 21 saves.
