MONTREAL — The newcomer got most of the glory last night, but the player who has established himself as a lineup mainstay in his first full year in North America made it happen with his typical brand of physicality in front of the net.

Center Carl Soderberg, an impact player on the third line since the Olympic break in February, capped an all-around outstanding night with the assist on Matt Fraser’s overtime goal in last night’s 1-0 Bruins victory in Game 4 that evened the best-of-seven Eastern Conference second-round series at 2-2 heading into Game 5 tomorrow night at the Garden.

Fraser was called up for Game 4 to replace Jordan Caron in the lineup. Soderberg’s been in search of some offense this whole series.

Soderberg had five shot attempts, including two on net and one that hit the crossbar. He threw his weight around for a couple hits and withstood some bone-rattlers from Montreal defenseman Douglas Murray late in the third period. Most important, he and his linemates did what they were supposed to do — take advantage of the Canadiens’ third pair of defensemen, Murray and Mike Weaver.

On the winning play, defenseman Johnny Boychuk’s shot went off the high glass, and Soderberg outmuscled Weaver for the puck in the left side of the slot. Soderberg’s backhand pass found Fraser for the tap-in game-winner at 1:19.

The goal ended what was an eventful night that could’ve easily ended in frustration.

“Yeah, it was nice to help the team win,” Soderberg said. “But we played a pretty good game, our line, and it’s all about team now. We’re really happy with this win.”

The scoring chance was reminiscent of many Soderberg and his linemates came up empty on throughout the game. The trio combined for 11 shot attempts and several misconnections on passes both at the Montreal blue line and around the Canadiens’ net. The crossbar Soderberg hit late in the first period, after Fraser’s tough angle shot went off goaltender Carey Price right to him in the slot, was also crucial.

“I just tried to elevate,” he said, “but it hit the crossbar.”

Soderberg — who was excused from and did not participate in the morning skate — had one assist in the prior three games in the series. Although he had seven shots on net, he hadn’t been able to provide the secondary scoring needed. He said he felt like he was playing well, but it just wasn’t showing up on the score sheet.

With Montreal’s top two defense pairs — Josh Gorges with P.K. Subban and Andrei Markov with Alexei Emelin — doing an airtight job on the Bruins’ lines centered by David Krejci and Patrice Bergeron, the Soderberg line broke through just in time.

“I thought he had a great game,” Bergeron said. “And you know he definitely gives us the depth that we need against that team. And it was great to see that line play like they did.”
