Robertson then pushed it to 5-2 at 8:32 when he one-timed a pass from Knies past Merilainen’s left pad.
“I thought we turned over a few pucks and then we got tired,” Green said. “It was one of those games where you haven’t skated in three days, you’re on a break, if you get tired, you’re going to be in trouble. Some of our shifts were longer because we turned over the puck not just in our zone or the neutral zone but in the offensive zone. Then you have to backcheck and play in your own zone for a while.”
Drake Batherson scored 14 seconds into the third period to cut it to 5-3 after he got behind Oliver Ekman-Larsson and took a pass from Dylan Cozens in the slot before shooting over a sprawling Woll.
Stutzle made it 5-4 at 5:07 when he pulled the puck off the half boards, cut into the slot and shot off Woll’s glove.
Knies responded to put Toronto up 6-4 at 5:53. After Morgan Rielly cut to the net, he swung a pass into the slot for Knies, who dove to slide a backhand past Merilainen.
Spence cut it to 6-5 on his own rebound at 9:18. After his initial shot hit Claude Giroux at the top of the goal crease, Spence shot from the slot past Woll, who was out of position.
Tavares then scored into an empty net at 18:44 for the 7-5 final.
“That was a playoff game,” Domi said. “Every game from here on out is going to be like a playoff game and that’s how you have to treat it. Everyone was battling, everyone was competing every shift.
“They’re a heck of a team. You have to respect them, they play hard and have some serious talent. When teams like that go head-to-head, especially when they’re a couple hours down the road and they’re ahead of us, we’re trying to claw back in here, every game is going to feel like (a battle) now.”
Nylander’s power-play goal gave the Maple Leafs a 1-0 lead 40 seconds into the first period when he took a pass from Matthews to put him in alone on Ullmark before beating the Senators goalie with a backhand deke.
Knies scored on the power play to make it 2-0 at 14:42, one-timing a pass from Domi over Ullmark’s glove from the slot. The goal ended a nine-game drought.
“In morning skate, we were working on it the whole time,” Knies said of the play. “It was a good sift from him there.”
