PITTSBURGH — Penguins defenseman Kris Letang didn’t even see the puck go in. He just heard the roar of the crowd.

That was all he needed on a night when his team was in dreadful shape earlier in the third period.

Letang capped a wild comeback, scoring the deciding goal with 3:06 to play, and Pittsburgh rallied with six goals in the third to beat the Vancouver Canucks 8-6 on Wednesday night.

Letang’s slap shot from the right circle beat Thatcher Demko to the glove side, completing Pittsburgh’s comeback from a 6-3 deficit.

“I was shooting next to a guy, so I couldn’t see behind him,” Letang said. “I just kind of reacted with the crowd.”

Evgeni Malkin scored twice and had three assists, and Jake Guentzel had two goals and two assists. Guentzel, on a three-game scoring streak, has 14 goals this season and six goals and 11 points on a six-game point streak.

Malkin tied a single-game career high, scoring five points for the first time since March 20, 2012.
