"It was pretty surreal," Power said. "It's obviously nice just to get it out of the way."
Power, who was selected with the No. 1 pick in the 2021 NHL Draft, made it 4-2 at 8:33 of the third period when he scored from the bottom of the left circle off a feed from Jeff Skinner. The 19-year-old defenseman has two points (one goal, one assist) in five NHL games since making his debut against the Toronto Maple Leafs on April 12.
"It's great," Buffalo forward Kyle Okposo said. "He's such a talent and you could tell that he wanted it. The last few games, he's up in the play all the time, he's always around the net and making great plays, so it was just a matter of time before he was going to get it. Great place to do it."
Rasmus Dahlin and Skinner each had a goal and an assist, Victor Olofsson had three assists, and Craig Anderson made 29 saves for the Sabres (30-38-11), who have won three in a row.
"I loved our third period because we give up a goal, the first goal of the period, and then the game tightens up and we were pushing each other," Buffalo coach Don Granato said. "Everybody collectively, we just said, 'Let's go. Let's get another. Let's go after them. We're not going to sit on a one-goal lead.'"
