But before the Metropolitan Division's leaders could take the game to the second period as a one-goal game, it was a penalty that this time bit Carolina. On what would be Toronto's only man advantage of the night, Auston Matthews had an initially blocked shot glance off of his leg and go by Kochetkov to give his team their two-goal gap back.
In the second period, Martin Necas was the beneficiary of some slick puck work from Teuvo Teravainen and Jesperi Kotkaniemi, briefly giving Carolina some hope.
However, 4:14 after it became a 3-2 game, an overskated puck in neutral ice by the Canes allowed Zach Aston-Reese to work in on a two-on-one and score once again.
There would then be just one goal in the third period, and to round out their night Toronto added one more on an odd-man rush. Morgan Rielly worked in on a two-on-one with Matthews and elected to shoot, placing a wrist shot by Kochetkov's blocker to make it a 5-2 contest.
The final horn would shortly thereafter sound, and Carolina would suffer their second loss to Toronto in as many tries this season.
The two teams will meet at PNC Arena to close out their season series next Saturday.
