UNIONDALE, N.Y. (AP) -Alex Ovechkin was held in check, but Alexander Semin scored twice for the Washington Capitals, who netted four goals in the first period and surged to their seventh straight win, 7-2 over the New York Islanders on Tuesday night.
Semin had two unassisted goals, and Brendan Morrison and Mike Knuble also scored against Dwayne Roloson in the first period for the NHL's most potent offense. Washington recorded only 12 shots in the frame but carried a 4-1 lead into the second.
Knuble's goal, scored during a power play just moments after Ovechkin struck Islanders defenseman Jack Hillen in the face with a shot, made it 3-1 with 1:47 left in the first. Semin pushed the advantage to three goals when he scored with 5.2 seconds left.
Roloson stopped eight of 12 shots before being replaced by Rick DiPietro to start the second. DiPietro allowed goals to defenseman John Erskine and Jason Chimera in the middle frame, and to Brooks Laich in the third.
Washington has scored at least four times in 10 of the past 11 contests (10-1). The Eastern Conference-leading Capitals (34-12-6) own the league's longest current winning streak.
