Tuukka Rask stopped 30 shots and the Boston Bruins won their fifth game in a row, 2-0, in Pittsburgh over a Penguins team missing Sidney Crosby and minus Evgeni Malkin for most of the game Saturday.
Crosby, the Penguins' leading scorer, was a surprise late scratch after he participated in the pregame warmup. There was no word on why the center was out.
Malkin, the team's second-leading scorer, got hurt on his first shift and did not play after the first period. There was no immediate report on the center's injury.
Milan Lucic scored in the first period and Zdeno Chara added an empty-net goal. Boston is 7-0-1 in its last eight games.
Rangers 2, Sabres 0 - Keith Yandle's third-period goal helped lift New York to a win in Buffalo.
Martin St. Louis added an empty-net goal and Mackenzie Skapski made 20 saves for his first career NHL shutout. It was just Skapski's second NHL win, and both milestones came this season against Buffalo.
The goal was Yandle's first since being acquired from Arizona on March 1, and gave New York its fourth straight win. All have come on the road, and the Rangers have allowed just two goals during the streak.
Canadiens 3, Islanders 1 - Tomas Plekanec and Max Pacioretty scored 2 minutes, 15 seconds apart in the second period, and Carey Price stopped 35 shots as Montreal dealt slumping New York a loss.
The Islanders have hit the skids at Nassau Coliseum, their soon-to-be former home once they relocate to Brooklyn next season. New York is 1-3-1 in its last five overall. At home, the Islanders have lost four straight in regulation, including three this past week.
