PITTSBURGH — The Montreal Canadiens scored five third-period goals, and the most important one came shortly after Pittsburgh tied the game.

Christian Dvorak scored the first of those five, helping the Canadiens end a lengthy road drought by beating the Penguins 6-3 on Saturday night.

Evan Rodrigues tied it at 1 with his power-play goal at 2:33 of the third period, but Dvorak scored 32 seconds later to help keep Montreal in front for good during a wild third period in which the teams combined for five goals in the final 2:37.

“You can’t always answer with scoring a goal back,” Canadiens coach Dominique Ducharme said. “But obviously, doing that and getting rewarded with a goal is huge. That’s a good way to react.”

Artturi Lehkonen also added to Montreal’s third-period fluffy, as well as Josh Anderson’s two empty-netters and an empty-netter from Tyler Toffoli. Jonathan Drouin scored his third goal in the second period for Montreal, which snapped a seven-game road slide and a two-game losing streak, and Jake Allen stopped a season-high 47 shots.

“Obviously, we’ve been down in the dumps a little bit as a group, and not playing our best hockey,” Allen said. “I just thought it was an important game to play well with a lot of effort, and most importantly, get the win.”

Sidney Crosby scored a goal and had two assists for Pittsburgh, which saw its five-game winning streak end. Rodrigues and Jeff Carter also scored for Pittsburgh, which frantically tried to rally after falling behind 3-1 and 4-2 in the third period.

Casey DeSmith stopped 27 shots in just his fourth start of the season. He hadn’t played since Nov. 13 at Ottawa.

“It was unfortunate that (Montreal) scored right after our power-play goal to tie it up,” Penguins coach Mike Sullivan said. “You’d like to think you can build on that and create some momentum. To give up that one as quickly as we did was a little bit discouraging.”

Montreal’s only other road victory this season came Oct. 28 at San Jose. The Canadiens are 2-9-1 on the road.
