The Bruins went to the man advantage after Brad Marchand drew a trip 40 seconds into overtime on just the third penalty of the game. The play began with a stellar rush from Torey Krug - playing in his 500th NHL contest - as the blue liner lugged the puck from deep in Boston's end through neutral ice and into the Islanders zone before finding Bergeron in the slot.
It was there that Bergeron quickly opened up and fired a wrist shot by the blocker of Islanders goalie Semyon Varlamov to secure the victory.
"It was an amazing play by Torey," said Bergeron. "I was reading that there were two guys going at him so I figured that if I would stay in that pocket and the puck would come, I'd have a little bit of time and I did. Great play by him."
The tally also gave the Bruins a power-play goal in 13 consecutive games, which is a new franchise record.
"Especially 4-on-3, we feel very confident with our group on the power play," said Marchand. "When you get a 4-on-3 - you just played a whole game - we feel pretty good about the situation we're in. We did a good job capitalizing."
Given the Bruins struggles in extra time (now 3-11), coupled with the Islanders' success (10-4), pulling out a victory had the Black & Gold feeling that some momentum might be back on their side.
"We hadn't had much luck in [overtime]," said Bruins coach Bruce Cassidy. "Good for us. They've got a great overtime record and shootout. Us not so much. Maybe this will be the beginning of balancing the scales with that part."
