Boston — Tuukka Rask rebounded from his first loss with 32 saves for his second shutout, Brad Marchand and David Krejci scored power-play goals in the second period, and the Boston Bruins beat the Buffalo Sabres, 4-0, on Monday night.

David Pastrnak had a power-play goal and Riley Nash scored for the Bruins, who won for the fourth time in five games. Rask recorded his 32nd career shutout after losing 5-2 against the New York Rangers on Saturday. He improved to 7-1 this season.

Robin Lehner made 38 saves for Buffalo, but he fell to 3-7-3 lifetime against Boston. It was just the Sabres’ second loss in six games.

Following a scoreless opening period that lacked many quality scoring chances, the Bruins moved ahead on Marchand’s goal 5:44 into the second. Matt Beleskey got the rebound from the edge of the crease and passed it to Marchand, who fired a wrister that hit off Lehner’s mask and top of his stick before going into the net.

Skating with a two-man, power-play advantage midway into the period, Boston increased its lead when Krejci one-timed a shot from the top of the left circle that slipped inside the left post for his first goal of the season.

Islanders 4, Canucks 2

New York — Cal Clutterbuck and Andrew Ladd scored 1:39 apart midway through the third period to lift New York over Vancouver, giving the Canucks their ninth straight loss.

Jason Chimera and Nikolay Kulemin also scored and Jaroslav Halak stopped 30 shots for the Islanders, who won for just the second time in seven games (2-3-2).

Daniel Sedin scored and Ryan Miller had 28 saves for Vancouver, which fell to 0-8-1 with eight straight regulation losses since opening the season with four wins.

Panthers 3, Lightning 1

Sunrise, Fla. — Reilly Smith scored a tiebreaking goal with 4:28 left, Roberto Luongo made 34 saves and Florida beat Tampa Bay.

Jonathan Marchessault got his seventh goal and Derek MacKenzie also scored for the Panthers.

Smith made it 2-1 after grabbing the puck inside the blue line away from Tampa Bay’s Victor Hedman. His shot from the left circle beat goalie Ben Bishop on the stick side.

Ondrej Palat scored for the Lightning, and Bishop stopped 29 shots.

MacKenzie scored an empty-netter with 36 seconds left.
