Hockey roundup: Three Michigan State recruits at U18 worlds; Bruins top Sabres

Bowen Byram and Peyton Krebs scored as Buffalo climbed within 4-2 in the closing minutes.

Sabres goalie Ukko-Pekka Luukkonen allowed four goals on 19 shots before Alex Lyon entered in relief following Arvidsson's second marker, which came just 16 seconds into the third period.

Buffalo had a 36-26 shot advantage, including 20-8 in the third period, but its power play went 0-for-5. Boston finished 1-for-6 on the man advantage.

The physical contest featured 47 penalty minutes for each team.

Following a scoreless opening period, the Bruins took over in the second, scoring on three of their 11 shots against Luukkonen.

Arvidsson broke the deadlock 4:54 into the middle frame, taking Aspirot's lob pass in ahead of the defense and beating Luukkonen five-hole with a backhander from the left circle.

A gaffe by Luukkonen helped Boston double its lead with 3:31 left in the period, as Geekie's high backhanded dump from the far side of center ice eluded him over the glove.

The Bruins' power play got in on the action 1:41 later. After Geekie's one- handed keep-in at the blue line extended the play, Zacha tipped in Pastrnak's shot from the top of the right circle while stationed in the bumper position.

Arvidsson made it 4-0 early in the third, prompting Sabres coach Lindy Ruff to change goaltenders. Aspirot banked a long feed off the boards to set up the play, leading Arvidsson down the left wing to score on a 2-on-1 rush with Zacha.

The Sabres struck twice in a 1:14 span to make things interesting. Byram accepted Beck Malenstyn's back pass for a wrister from the top of the right circle to break Swayman's shutout bid with 6:06 left.

Krebs soon made it 4-2, batting down and scoring the rebound of a Rasmus Dahlin point shot that caromed off the post and back into the crease.
