DALLAS (AP) - Tyler Seguin scored his fifth power-play goal of the season in Dallas' four-goal first period, and Stars beat the Buffalo Sabres 5-1 on Saturday night.

Seguin's goal on a slap shot from the left faceoff circle made it 4-0 just 12:51 into the game.

Remi Elie, Radek Faksa and Stephen Johns also scored in the first, and Antoine Roussel added a second-period goal. Johns' goal chased Buffalo goaltender Robin Lehner from the game at 10:27 of the first.

Lehner made only four saves before Chad Johnson came in and stopped 13 shots.

Kari Lehtonen had 27 saves to win his second straight start. Ryan O'Reilly broke up Lehtonen's shutout bid by winning a faceoff and sending a shot between the goalie's legs late in the second.

John Klingberg had a season-high three assists.

Elie opened the scoring at 3:09 of the first. Roussel intercepted a clearing pass on the left-wing boards and sent a slap shot at Lehner. Elie took the rebound in front for a short wrist shot into the net.

Faksa scored at 7:07. Lehner deflected Gemel Smith's cross-ice pass in front of the net and on to Faksa's stick for a tip-in.

Smith also assisted on Johns' goal, dropping a pass back into the slot for the defenseman. Johns put a wrist shot past Lehner.
