UNIONDALE, N.Y. – Chris Kunitz scored his second power-play goal of the game 8:34 into overtime, off a pass from Sidney Crosby, and the Pittsburgh Penguins shook off an early deficit and a late blown lead to beat the New York Islanders 5-4 on Sunday in Game 3 of the first-round series.

The Eastern Conference's top-seeded team rode severe ups and downs in taking a 2-1 lead in the best-of-seven matchup.

Pittsburgh trailed 2-0 just 5:41 in but rallied to lead 3-2 before the first period was over. The comeback started with power-play goals just 19 seconds apart by Jarome Iginla and Kunitz.

The Penguins seemed in control in the third period, but New York erased a 4-2 deficit on goals by Kyle Okposo and John Tavares.

Game 4 is Tuesday on Long Island.
