Tuukka Rask stopped 30 shots and the Boston Bruins won their fifth game in a row, 2-0 over a Pittsburgh 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 past eight games.
