Islanders 6, Penguins 3: Kyle Okposo erupted for four goals, including the game winner with just over eight minutes remaining in the third period, as host New York upended Pittsburgh in a battle between two of the top teams in the Eastern Conference.

Just over five minutes after tying the game, Okposo completed his first career hat trick with a well-placed wrist shot from the slot and added some insurance with 2:31 left to lead the Islanders to their fourth consecutive victory. Ryan Strome scored a second-period goal, Michael Grabner added an empty-netter, captain John Tavares and Josh Bailey notched three assists apiece and Jaroslav Halak stopped 21 shots.

Captain Sidney Crosby scored twice - his first multi-goal effort since Oct. 28 - and added an assist for the Penguins, who have lost three straight meetings between the Metropolitan Division rivals. David Perron also tallied and All-Star Marc-Andre Fleury made 29 saves in defeat.

Crosby opened the scoring during a power play at 10:52 of the first period as the rebound of Chris Kunitz's shot deflected off his elbow and in, and Perron doubled the lead 90 seconds later with a low blast from above the right faceoff circle. Okposo halved the deficit with 3:09 remaining in the session, as Tavares used a sensational move to get around Pittsburgh defenseman Simon Despres before whipping a pass that glanced off Okposo's skate and past Fleury.

Strome drew the Islanders even 12:31 into the middle period, outmuscling a pair of New York defenders before beating Fleury between the pads. Crosby scored a back-breaker with 4.4 seconds remaining in the session - gathering a cross-ice feed from blue-liner Paul Martin and lifting the puck over a fallen Halak - but Okposo responded at 6:42 of the third, pouncing on a rebound and lofting a backhand shot past Fleury.
