BUFFALO -- Robin Lehner made 37 saves, and four players scored to lift the Buffalo Sabres to a 4-0 win against the Ottawa Senators at KeyBank Center on Saturday.
Lehner had 16 saves in the third period for his first shutout of the season, fourth of his NHL career and first against his former team.
"It is a big win, but the big piece is [Lehner] there; [Lehner] gave us a chance all game," Sabres center Ryan O'Reilly said. "Without him playing the way he did, it would have been a much different story."

"It's nice, it's always nice, but I have got to be honest, every two points we get is a really good feeling, every win we get," Lehner said. "We've been in some stretches where we haven't been consistent enough, some stretches where we haven't scored goals, some stretches where me and [Anders] Nilsson wish we came up with some more saves. But wins right now is a really good feeling."
The Sabres (21-20-10) ended a three-game losing streak. The Senators (27-17-6) went 1-2-0 on their three-game road trip.
Kyle Okposo gave Buffalo a 1-0 lead with 9:49 left in the first period on a strong individual effort after taking a pass from Josh Gorges, who returned to the lineup after missing 12 games with a hip injury.

O'Reilly made it 2-0 with 3:09 left in the second period when he tipped a shot by defenseman Rasmus Ristolainen past goalie Mike Condon for his 10th goal.
Sam Reinhart made it 3-0 5:53 into the third period. After receiving a pass from Jack Eichel, Reinhart's initial shot was stopped by Condon, but he gathered the rebound and scored his 11th of the season.
Marcus Foligno scored to make it 4-0 with 9:09 left in the third after he received a pass from Eichel and shot it past Condon. Andrew Hammond replaced Condon following Foligno's goal and made one save; Condon had 21 saves.
"I felt some pressure needing to perform and play a good game for those guys," Foligno said. "Jack and Sam have been working hard, we've all been working hard, but we just haven't had results, and it's nice to have results."

Goal of the game

They said it
"[Sabres goalie Robin Lehner] played really well. We had enough shots, that wasn't the issue, but we didn't pay the price in front of the net. He played well, but we definitely didn't pay the price in front of him, and a goalie that size that's doing it that well, you can't expect to score goals if you're not doing that. ... There was no traffic in front of him. There was not enough fight there." -- Senators coach Guy Boucher
"Any [former] team you get a little more firepower. [Lehner] played phenomenal tonight (and) I think all year. He's been one of the most consistent players. He's given us a chance so many times. It's nice to see him beat his old team like that in a shutout. He played phenomenal tonight." -- Sabres center Ryan O'Reilly

"That's the way we're approaching every game. We want to get to our best. We want to get to where we're a good team every night." -- Sabres coach Dan Bylsma
