Tuukka Rask dominated at one end of the ice and his teammates controlled the opposite side, helping the Boston Bruins play a near-perfect game on the road to earn their fourth straight win. Brad Marchand scored the go-ahead goal in the second period and the Bruins continued their dominance of the Islanders with a 4-1 victory on Tuesday night -- Boston's 16th victory in its last 20 games against New York.
