A Lassi Thomson wrister from the high slot 4:01 into the third frame broke the Toronto shutout bid. Bobby McMann restored the Marlies’ two-goal advantage 23 seconds later, shortly after Belleville initially got on the board.
Again, the Senators were brought to within one, as an Egor Sokolov dump-in from the red line found the back of the net after the awkward bounce beat Erik Kallgren with 5:50 left to play.
After sustained pressure in the Toronto zone, Antti Suomela sent a long clearance down the length of the ice to find the empty net with just over a minute to play, clinching the Marlies’ victory.
