Norris batted the puck out of midair off a pass by Tkachuk at the edge of the crease to make it 2-1 at 15:01.
“I think we battled hard,” Stutzle said. “I think everybody played hard. Every line played strong, and I think [Tkachuk], Josh and [Giroux], when they had the puck in the [offensive] zone, were really dangerous.”
Tkachuk tapped in a long-range backhand seam pass from Giroux on the rush to make it 3-1 at 2:10 of the second period.
“It was a huge relief and just an awesome feeling,” said Tkachuk, the Ottawa captain. “Forsberg made some huge saves to keep us in it, so it’s a huge relief. And we get Jacques his first win [in] part two with us.”
Rakell finished a centering pass from Sidney Crosby on the rush to cut it to 3-2 at 4:59. It was his first goal this season.
“It feels good to get the first one,” Rakell said. “Hopefully, it just takes some weight off my shoulders, and I can just start helping out our team a little bit more.”
Brannstrom scored in tight off a pass from Tkachuk on a 2-on-1 to extend the lead to 4-2 at 7:30. It was Brannstrom’s first goal in 14 games.
Drew O'Connor tipped a Marcus Pettersson point shot to cut it to 4-3 at 1:51 of the third period.
“It was a big point, don’t get me wrong,” Pettersson said. “It was a big point. But we didn't give ourselves a chance to get two.”
