Pittsburgh's Kris Letang scored the only goal of the shootout with a pretty backhand past Islanders rookie goalie Jean-Francois Berube to lift the Penguins to a 2-1 victory on Tuesday night.
Marc-Andre Fleury stopped Frans Nielsen, Kyle Okposo and John Tavares in the shootout as Pittsburgh strengthened its hold on the first wild-card spot in the Eastern Conference.
Fleury finished with 25 saves for the Penguins. Chris Kunitz scored his 14th goal of the season in the 800th game of his career. Sidney Crosby picked up the secondary assist to extend his points streak to nine games.
Berube made 33 stops in his third NHL start, including several in the extra period. Okposo's score at 14:35 of the third sent the game to overtime, but the Islanders couldn't pick up the additional point when they failed to solve Fleury in the shootout.
