David Backes scored in the sixth round of a shootout to lift Boston to a 3-2 win over the Vegas Golden Knights on Wednesday night for the Bruins' season-high seventh straight victory.

Jake DeBrusk and Brad Marchand scored in regulation for Boston, which is 8-1-1 in its last 10 on the road — including wins in the first four games of a western trip. The Bruins' win streak is their longest since a 12-game run in 2014.

With the assist, Krejci extended his point streak to five games (two goals, eight assists).

With the assist, Krejci extended his point streak to five games (two goals, eight assists).

Smith tied it late in the first period when he punched home a rebound from Cody Eakin's shot from the point. Smith, who now has at least one point in five of his last seven games, scored his first goal since Dec. 30 and became the seventh Golden Knights player to hit the double-digit mark in goals. With the assist, Eakin has at least one point in five of his last six games with a goal and four assists.

Marchand gave the Bruins a brief lead, as he took a pass from Danton Heinen and beat Fleury with a blast 69 seconds into the third.
