BOSTON -- The Boston Bruins moved to within one victory of the Eastern Conference finals with a 4-2 victory over the Montreal Canadiens in Game 5 of their semifinal series Saturday night.

Center Carl Soderberg scored one goal and set up two others as the Bruins took a 3-2 lead in the series.

The Bruins, who earned a 1-0 Game 4 win when left winger Matt Fraser capped his first career playoff game with the overtime goal, built a 3-0 lead Saturday. The last two goals came 32 seconds apart early in the second period -- when Boston snapped its 0-for-39 power-play drought against Montreal that dated back to 2009.

Right wingers Reilly Smith (his fourth of the playoffs), Jarome Iginla (No. 4) and Loui Eriksson (No. 2, to go with an assist) also scored for the Bruins, while right winger Brendan Gallagher and defenseman P.K. Subban both scored their fourth respective goals of the playoffs for the Canadiens.

Soderberg became the sixth Bruins player to score his first career playoff goal when his shot from the slot hit Canadiens goaltender Carey Price and went in at 13:20 of the first period.

Two penalties called on Montreal center Tomas Plekanec led to the power play goals. Smith tipped a shot by defenseman Dougie Hamilton off Price and then defenseman Mike Weaver 1:04 into the second period. Plekanec came out of the box and then went right back in, leading to defenseman Torey Krug setting Iginla up alone in front.

The Montreal power play got one back with 5:21 left in the second period to make it 3-1 when Plekanec's shot hit Gallagher and beat Boston goalie Tuukka Rask.

Eriksson, who assisted on the Soderberg goal, picked up a rebound of a Fraser shot and beat Price with 5:48 left in the third to restore the Bruins three-goal lead.

Soon after, the Canadiens pulled Price. Then, with defenseman Matt Bartkowski off for holding, Subban blasted his fourth goal of the series home with 2:29 left.

Game 6 is Monday night in Montreal and the teams would return to Boston for Game 7 on Wednesday if necessary. The winner gets the winner of the Pittsburgh Penguins vs. New York Rangers series.
