Columbus needed just 3:31 to take a 1-0 lead as the Blue Jackets got an early power play and took advantage, as Voracek had time and space in the right circle and was able to beat Buffalo goalie Ukko-Pekka Luukkonen far side. Columbus then doubled the lead at 12:49 as Bemstrom stripped Buffalo's Rasmus Dahlin at the blue line, carted the puck 120 feet, shrugged off a check and lifted a backhander over Luukkonen to complete the breakaway and make it 2-0.
But Buffalo cut the CBJ lead in half with 2:48 left in the period as Casey Mittelstadt scored. Vinnie Hinostroza was open in the slot and fired wide of the right post, but Mittelstadt found the rebound and quickly roofed a shot over Joonas Korpisalo. Columbus nearly got the goal back moments later, but Luukkonen made a second great save of the period on rookie Yegor Chinakhov.
Korpisalo was solid early in the second period in his preseason debut, making big stops on Kyle Okposo and Drake Caggiula early in the frame before Columbus pulled away in the frame. Jenner made it a 3-1 game on the power play just 1:35 into the frame as Patrik Laine found Voracek streaking into the zone, and his pass to Jenner in front set him up to score past Luukkonen. Voracek happened upon a loose puck and set up a wide-open Laine to make it 4-1 at 16:12, and Bjorkstrand beat Luukkonen with a backhander at 17:24 to make it 5-1.
Luukkonen made some nice stops on Zach Werenski and Chinakhov early in the third to keep the score where it was, and Buffalo got one back 6:26 on its first shot of the frame as JJ Peterka won a race to a puck and shot it past the blocker of Daniil Tarasov. Mittelstadt got another to make it 5-3 with 8:45 to go as his sweet writer from the right circle beat Tarasov over the far blocker, but that was it as Buffalo's comeback effort fell short despite some closer calls late.
