Chinakhov, 2021 first-round pick Cole Sillinger and defenseman Jake Christiansen all had good looks in the first period, but none could best Toronto goalie Ian Scott. Meanwhile, the Maple Leafs scored twice on the other end to take a 2-0 lead after 20 minutes. Nicholas Robertson was left alone in front 6:16 into the game and put an Alexander Steeves pass past CBJ goalie Jet Greaves, while at 9:11, Semyon Der-Arguchintsev pushed a rebound into the net.
But Columbus dominated the second period and made it a 2-2 game in the first 10 minutes. First, Fonstad's clearing attempt off the wall hit Mullin in stride for a 2-on-1, and the latter kept the puck and fired a bar-down wrist past Scott at 1:57. Then at 9:21, just after a CBJ power play expired, the two switched roles, with Mullin's pass across the crease to Fonstad put on a tee for an easy finish. But Toronto took a 3-2 lead on the power play with 4:11 left in the period as Matt Hellickson scored through a screen.
Sillinger hit the post early in the third but linemate Chinakhov didn't miss a few shifts later, taking a feed from Sillinger in transition and ripping a shot past the glove of Scott at 5:33. Columbus thought it had taken the lead with three minutes to go on a goal by 2020 fifth-round pick Ole Julian Bjorgvik-Holm, but it was waved off for goaltender interference.
It didn't take long in overtime, though, for Columbus to win it off an offensive zone faceoff. Dunne won the puck to Meyer, who reversed it far side to Christiansen. From there, a tic-tac-toe move saw Christiansen return it to Meyer in the right circle, and the Powell, Ohio, native fed it to Dunne at the back post for an easy tap-in.
