Semin got help on his milestone goal as his shot from the right-wing boards hit the helmet of Islanders defenseman Travis Hamonic and caromed off the post past goalie Rick DiPietro at 5:33 of the third period.
Malkin flung a pass from the middle of the right wingboards in the New York end back to Murray, who took a hard drive from above the left circle that sailed past Nabokov to make it 4-2.
