Marchand has 23 points (eight goals, 15 assists) during his streak; Pastrnak has 27 points (13 goals, 14 assists) during his run.

"A lot of that comes … we are playing well as a team and that always helps, and that's a huge pickup," Pastrnak said. "We're all doing well and playing with a lot of confidence, so obviously that helps. But yeah, we're winning, and that's the major thing."

Anthony Duclair and Connor Brown scored, and Craig Anderson made 27 saves for the Senators (3-8-1), who are 0-4-1 on the road.

The game was tied 2-2 entering the third period.

"You know what, I think it's a good learning lesson for us," Ottawa coach D.J. Smith said. "You've got to stay with the plan, you've got to stay [with it] when you're playing a team as good as these guys. I thought we made two mistakes tonight and they end up in the net. …

"But I really did like our effort for a lot of the game. This is one of the best, if not the best team in the League, and I thought we stayed with them."

Pastrnak gave Boston a 1-0 lead on the power play at 1:17 of the first period. Bruins defenseman Torey Krug shot the puck into the offensive zone from his own end, and Pastrnak won a race to the puck before taking it to the net and scoring.

Senators forward Scott Sabourin left the ice on a stretcher at 3:08 after a collision with Bruins forward David Backes.

Their heads appeared to make contact, and Sabourin remained on the ice for more than 11 minutes while he was attended to before being wheeled off. He was hospitalized overnight, and the Senators said he was conscious and speaking.

Backes left the game following the collision with an upper-body injury.

"Yeah, it was tough to get her going after you see [Sabourin] on the ice. It was pretty emotional for all of us," Ottawa defenseman Mark Borowiecki said. "That was one of the first ones, I think for me personally, I've ever been a little choked up. I love that guy. We all love him in here. He's a team-first guy, would do anything for anyone, and to see him down there like that, we were all pretty shook up."

Duclair tied it 1-1 at 12:04.

Bergeron gave the Bruins a 2-1 lead at 1:51, but Brown tied it 2-2 at 3:04.

With the Bruins already killing a minor penalty for too many men on the ice, Marchand was called for a hooking minor and a double minor for spearing at 6:08. The Bruins killed 55 seconds of a 5-on-3 and then 1:05 more of an Ottawa 5-on-4.

"For sure, it definitely helped us," Bergeron said. "And they got some good looks, Tuukka made some great saves, but at the same time, I thought we did a good job overall and yeah, you often say that power play or penalty kill, special teams can give you some momentum, and I thought tonight it was the penalty kill that did it."

Danton Heinen put the Bruins ahead 3-2 at 5:43 of the third period, and Marchand made it 4-2 with a power-play goal at 6:50.

Jake DeBrusk made it 5-2 with 3:44 left.

"He is on another level right now. His ability to make plays … both his pass to [Bergeron] on the second goal and his pass to me on the third, he's just seeing things that other guys just could never see." -- Bruins forward Brad Marchand on linemate David Pastrnak
