The win avenges a 2-0 loss to Toronto on Tuesday and ends a three-game losing streak for the Sabres, who have won just three of their last 12 games to sit 19-19-5 for the season.

Buffalo gained the early advantage with two goals on their first three shots against Toronto goalie Jonas Gustavsson, who claimed a shutout on Tuesday.

Matt Ellis scored one minute into the game when his centering pass deflected off Maple Leafs defenseman Cody Franson. Paul Gaustad then doubled the lead three minutes later with a wrist shot from distance that Gustavsson probably should have saved.

The Maple Leafs levelled the score late in the period with goals by Mikhail Grabovsky and Joey Crabb three minutes apart.

The Sabres then scored the game-winner in the second period when Jason Pominville converted a beautiful pass from Thomas Vanek, who threaded the puck through two Maple Leafs defenders.

Sabres goalie Ryan Miller made 24 stops, nine of them in the final period, to help deliver the win.
