The power play has been a concern of the Bruins for a long time. But last night at the MTS Centre, the man-advantage finally produced a victory for them.

After he drew a penalty just nine seconds into the third period, Brad Marchand scored his eighth goal of the year on the ensuing power play, beating Ondrej Pavelec with a backhander over the glove 36 seconds into the final period, and the B’s hung on for the 3-2 win over the Winnipeg Jets.

The B’s have now scored three power-play goals in their last four games, and Marchand said it’s no accident.

“It’s huge,” he said. “A few games back we had a big meeting and wanted to make sure we really improved on the power play. In (three of) the last (four) games we’ve had a power-play goal and we’re very proud of that. You see like tonight, it wins games for us and that’s what we need.”

The win, which snapped a two-game losing streak, didn’t erase all the scoring problems of the B’s, but the fact that it was their longtime bugaboo that helped them win made it all the more gratifying.

“There’s a lot of pressure that comes from the outside, there’s a lot of pressure that comes from the inside,” said coach Claude Julien. “Guys want to do well, but I think it’s important that we understand that how we execute and how we compete is what’s going to make things happen. We needed to move the puck quicker and crisper. The last couple of games have been better, but you don’t want to get carried away with that stuff. You want to build on it. We capitalized on our only power play tonight and that’s a good sign. It turned out to be the winning goal.”

The game wasn’t always pretty from a Bruins standpoint. There were a couple of defensive breakdowns in front of goalie Tuukka Rask that led to Winnipeg goals, but unlike their last two games, the B’s battled for three periods. With three of the four lines jumbled because of the absence of Milan Lucic (personal reasons), the B’s got very good games from Tyler Seguin, who scored on a tip in front and also had a big diving backcheck on a Winnipeg odd-man rush, and Chris Bourque, who picked up an assist on Marchand’s goal and earned a promotion in the game to the David Krejci line for his all-around sound play.
