Rutta scored 3:46 into the game when he wheeled around the back of the net and tossed the puck out front, where it hit Toronto center Mitch Marner's stick and squeaked through Andersen and the post.

It wasn't until the midway point of the second that Toronto picked up its pace and was awarded its first power-play opportunity after some sustained pressure by Matthews in the offensive zone.
The Leafs failed to capitalize on the man advantage, but Zaitsev put them on the board soon after, streaking in from the Hawks' blue line and taking a pass from Brown before snapping the puck five-hole on Forsberg at 10:20.
Matthews almost tied the score on a 2-on-1 rush five minutes later with a toe-drag into a wrist shot, but Forsberg stayed with him and got his right arm on the puck.
