Knies shot into an empty net at 17:01 to make it 5-2 before Guenther cut it to 5-3 on the rush at 18:53.
The Mammoth went up 1-0 at 18:49 of the first period. Carcone shot over Stolarz’s right shoulder from the top of the crease after taking a pass from Lawson Crouse, who was behind the net after stealing the puck from Brandon Carlo on the forecheck.
Nylander tied it 1-1 at 4:46 of the second period, flipping a shot over Vanecek’s glove from the top of the crease during a delayed penalty after Knies poked the puck to him through traffic. Nylander has an eight-game personal point streak (16 points; five goals, 11 assists).
Matthews scored for the third straight game, putting Toronto ahead 2-1 at 8:56 when he one-timed a pass from Maccelli over Vanecek’s glove from the top of the left face-off circle.
“Maccelli was all over it tonight: slippery, made a great pass to me on my goal and seemed like the puck was following him,” Matthews said. “He had a big goal for us there. I’m sure that one feels good against his old team.
“I think the last week or so I’ve been getting good opportunities throughout each game. Just want to keep that going and play well defensively and be responsible.”
Sergachev tied it 2-2 at 16:27. McCabe’s backhanded clearing attempt from below the goal line was knocked down by Dmitri Simashev, who fed Sergachev for a one-timer just inside the blue line. The assist was the first NHL point for Simashev in his 14th career game.
“They played well. They’re a great team,” Sergachev said. “They played fast, they play with pace, their forecheck was great and it caused us problems because we didn’t do what Coach asked us to do, which was play simpler in the neutral zone and our zone.”
