Jack Eichel had three points (one goal, two assists) and Jeff Skinner had a goal and an assist, and Rasmus Dahlin had three assists for the Sabres, who won their first two games of the season for the first time since 2012-13. Carter Hutton made 18 saves.
"We wanted to come out and show the fans what it's going to be like this year and the type of product we want to put on the ice, just get them excited for the season," Eichel said. "I think we did a pretty good job of that tonight. It's all about consistency, and we just want to keep doing it every night and make this place a hard place to come in and try to play."

Buffalo went 3-for-3 on the power play after going 1-for-2 in a 3-1 win at the Pittsburgh Penguins on Thursday.
"We know that those are huge opportunities in the League the way it is today and how tight these games are," Sabres coach Ralph Krueger said. "Our penalty kill, again, has been outstanding. But more than anything, the way we're moving the puck, the way we're staying in motion. We're not stuck anywhere in one spot, and the way everyone's filling the lanes, we're lethal there right now."
