The goal came from an unlikely source: Matt Carkner, who didn't even become a full-time NHL player until this season. He blasted a shot past Marc-Andre Fleury from above the right circle.
It was, he conceded without reluctance, the biggest goal of his life.
"Yeah, a little bit, he said.
"Definitely an unbelievable feeling. All of the guys, we battled hard all night and stuck with it even though we lost some momentum here and there. Three overtimes, and we knew it wasn't going to be a pretty goal, and I think it deflected off someone — I don't even know how it went in.
"But it's just a great feeling."
The series, which the Penguins lead 3-2, now shifts to Scotiabank Place for Game 6 on Saturday night.
