BOSTON -- Bruce Cassidy got a win in his coaching debut, and Patrice Bergeron had a goal and three assists when the Boston Bruins defeated the San Jose Sharks 6-3 at TD Garden on Thursday.
The Bruins (27-23-6), who promoted Cassidy from assistant coach after firing Claude Julien on Tuesday, ended a two-game skid despite playing without defenseman Zdeno Chara because of illness.
"I feel great," Cassidy said. "It's been a busy two or three days, so I'll tell you this, I'm going to sleep well tonight. But tomorrow's a new day, we'll get back to work and see if we can build on this one. But I mean, yeah, who doesn't enjoy a win?"

Unsung performance of the game
The line of Schaller, Dominic Moore and Riley Nash got rewarded when Schaller scored but the importance of that line couldn't be understated. Schaller's goal came after a Sharks penalty kill could've shifted momentum. The Bruins fourth line did yeoman's work on the forecheck and the cycle before the goal and throughout the game. All three forwards contributed to Boston's 2-for-2 penalty kill performance.
They said it
"You knew they would have a little wakeup call over there and they would come out ready to play. You know what, as players you understand that, you have to match the effort. That's the bottom line and the puck was going in the net different ways early on and they found a way to keep it going." -- Sharks captain Joe Pavelski
"You jump on the ice and all of the sudden you're in the slot with the puck rolling at you. Those are the ones you dream about. I was able to put that in and the rest of the game started to slow down for me. I stopped squeezing my stick into a bunch of shrapnel out there and was able to capitalize." -- Bruins forward David Backes on scoring in the opening minute of the game
