"I would have liked to have put it in myself," said Rielly, whose 10th goal is an NHL career high. "It's all good."
Toronto pushed the lead to 3-1 at 5:49 of the third period when Nylander set up Marleau with a pass across the slot.
"I just saw him driving the far post," Nylander said. "I didn't really have anything to shoot at, so I just floated a pass to him."
Mitchell Marner circled the net and passed to a wide-open Tavares to make it 4-1 at 8:29. Marner has 13 assists in the past eight games.
Toronto blocked 19 shots, led by defenseman Nikita Zaitsev, who had five.
"We knew their game plan a little bit," Andersen said. "They want to throw everything at the net, and we came ready to block some shots and be in the lanes for that."
The Hurricanes are 2-4-1 in their past seven games.
"We're not committed enough to doing it every single time we're out there," Williams said. "That was a tough one because we were right there."
