Jake DeBrusk, Elias Pettersson and Liam Ohgren scored in the third period for the Canucks (16-21-5), who have lost four straight (0-2-2) and six of their past seven. Brock Boeser had two assists, and Thatcher Demko made 15 saves.
“Obviously, we knew Buffalo is one of the hottest teams in the League. We weren’t ready to play. That’s on us,” DeBrusk said. “‘Demmer’ kept us in it, and I liked the fight we had in the third period, but in saying that, there’s a fine line between winning and losing. Little plays at the beginning of the game, little plays at the end of the game can make a difference.”
Tage Thompson gave Buffalo a 1-0 lead at 2:01 of the first period when he collected a loose puck in the slot and beat Demko inside the left post.
Ryan McLeod buried a wrist shot off a feed from Tuch on a short-handed 2-on-1 rush to make it 2-0 at 11:24.
“We’ve killed a lot together over the last two years now,” Tuch said. “Always looking for that, especially when you face a power play. Sometimes there’s only one defenseman out there, so you've got guys that are thinking about offense so you may be able to jump them. … If we catch them cheating, we can capitalize on them. We know we have the skill to do so, but we don’t try to sacrifice defense to do that.”
Tuch pushed it to 3-0 at 9:37 of the second period, taking Byram’s backhand cross-crease pass at the back door and quickly putting it past Demko, who couldn’t get over in time.
Zach Metsa scored his first NHL goal to put the Sabres ahead 4-0 at 6:13 of the third period. The defenseman, who was playing in his 12th NHL game, jumped up to the right circle and put a wrist shot to the far side.
“Crazy feeling,” said Metsa, who signed his first NHL contract in the offseason after playing two seasons on an American Hockey League contract with Rochester, Buffalo’s affiliate. “It’s something you’ve dreamed about since you were a little kid.”
