Jeff Skinner scored twice, with his second capping a three-goal, second-period outburst, and the Buffalo Sabres defeated St. Louis 6-2 Wednesday night, snapping the Blues' seven-game winning streak.

Minor-league callup Ukko-Pekka Luukkonen stopped 34 shots for his fourth career NHL win, and first since Dec. 16. Getting his second start since Eric Comrie sustained a lower-body injury, Luukkonen's best save came with 4:24 left in the second period, when he kicked out his right pad to stop Vladimir Tarasenko set up on the doorstep.

Rookie Jack Quinn capped the win with two third-period goals, and Victor Olofsson and Dylan Cozens also scored.

Pavel Buchnevich and Brayden Schenn scored for the Blues, and Jordan Kyrou had an assist to extend his points streak to six games (two goals, nine points).

Jordan Binnington stopped 25 shots in his first loss in seven starts, and was denied in his bid to win his 100th career game.

With St. Louis trailing 4-1, Buchnevich scored a second time 6:11 into the the third period, but the goal was disallowed after the Sabres challenged the play for being offside. Replays showed Tarasenko losing possession just before he entered Buffalo's zone a step ahead of the puck.

A day after Buffalo scored three times in the first 2:13 at Montreal, Skinner opened the scoring 18 seconds into the game.

The Sabres then took control with three goals over an 11-minute span in the second period, and after Buchnevich tied the game with a power-play goal 53 seconds into the frame.

Skinner capped the surge by driving in from the left boards, stick-handling the puck through this legs to avoid Justin Falk, and then going against the grain by back-handing in a shot inside the left post.
