WASHINGTON - Torrey Mitchell scored the tiebreaking goal with 7:42 left, Jhonas Enroth stopped 43 shots, and the Buffalo Sabres beat the Washington Capitals 2-1 Saturday night for their third straight win.
Washington's Braden Holtby made the initial save after Brian Gionta picked up a loose puck in the left circle, but Mitchell knocked in the rebound for his third goal of the season.
Matt Moulson also scored for Buffalo, which began the day last in the league with 12 points and has won three in a row for the first time since Feb. 25-28.
Matt Niskanen tied the score for Washington with a power-play goal at 5:54 of the third period, and Holtby finished with 24 saves.
Enroth, starting in place of the injured Michal Neuvirth, made 20 saves in the second period alone, and closed with several in the final minute after Washington pulled its goalie.
The Sabres were playing their first game since Tuesday following the postponement of Friday night's home game against the New York Rangers due to the severe snow storm in the Buffalo region.
Washington had won two straight and five of seven.
With Mike Weber off for hooking, Niskanen tied it on Washington's 35th shot of the night. He took a pass from Nicklas Backstrom and his shot from the slot deflected off a Sabres defender and past Enroth for his first goal of the season.
The Capitals had gone four games without a power-play goal.
Washington outshot Buffalo 31-14 over the first 40 minutes but trailed 1-0.
Midway through the second, Tyler Ennis fired wide to the right of Holtby. The puck bounced off the end boards to Moulson left of the net, and he backhanded a shot past the sprawling Holtby at the 9:45 mark.
The first 20 minutes were relatively quiet until Washington's Michael Latta and Buffalo's Marcus Foligno dropped their gloves and traded punches at the 17-minute mark.
