Matt Moulson scored the only goal of the shootout to lift Buffalo to a 5-4 victory over the Ottawa Senators on Monday night for the Sabres' sixth straight home win.
Moulson and Rasmus Ristolainen also scored in regulation for Buffalo, while Brian Flynn and Marcus Foligno each had a goal and an assist as Buffalo has won a season-high four straight overall. The Sabres improved to 10-3 since starting the season 3-13-2.
Alex Chiasson had a goal and an assist for the Senators, and Bobby Ryan, Curtis Lazar and Mark Stone also scored.
The game was moved from Feb. 20 to accommodate the rescheduled Nov. 21 game between the Sabres and New York Rangers.
Buffalo's Jhonas Enroth and Ottawa's Robin Lehner both had 29 saves through overtime. Enroth also stopped Mika Zibanejad, Kyle Turris and Ryan in the shootout, while Lehner stopped Tyler Ennis and Zemgus Girgensons.
Buffalo had the first five shots of the game, including an attempt by Cody Hodgson as he glided into the slot and put a wrist shot off the cross bar 2 1/2 minutes into the game.
Enroth made a sliding right pad save to deny Clarke MacArthur after a deflected pass, but Ottawa scored less than a minute later.
Zibanejad won a loose puck to Mike Hoffman, who pushed a spinning backhand pass through the crease to Ryan for the goal.
Sabres defenceman Nikita Zadorov flipped a puck in from the left point that arched into the slot, where Chris Stewart redirected the puck past Lehner with a baseball-type swing of his stick. After video review, it was deemed that Stewart's stick was above the crossbar and the goal was disallowed.
The Sabres tied it up at the 4:11 mark, as Brian Gionta moved off the half wall to find Stewart to the right of the goal. Stewart passed the puck to the left circle, where Ristolainen beat Lehner along the ice to make it 1-1.
Buffalo secured its first lead when Girgensons dug Andrej Meszaros' point shot free from Lehner, and Moulson backhanded the loose puck into the goal.
Just 32 seconds later, it was Brian Flynn who found Foligno on a 3-on-2 to make it 3-1.
Another odd man rush for the Sabres was foiled when Lehner got a pad on Flynn's shot in close.
Then Erik Karlsson pinged a shot off the crossbar midway through the second period.
Ottawa did halve its deficit when Stone finished Turris' pass on a 3-on-2 with 6:28 left in the second.
The Senators needed just over 2 minutes of third-period play to tie the score, as Lazar crashed the crease to jam a loose puck past Enroth for his first NHL goal.
Ottawa took a 4-3 lead when Enroth misplayed Chiasson's low backhand shot.
The Senators managed 10 of the period's first 11 shots, but Flynn shot Foligno's rebound past Lehner to tie the score with 3:29 remaining in regulation.
Ottawa carried play in overtime, outshooting Buffalo 4-2.
NOTES: Sabres C Torrey Mitchell was injured blocking a shot in the first period. He returned to the ice, but left the game before the second period. ... The Sabres are 6-0-1 when leading after two periods.
