Scott Wedgewood made 32 saves for the Devils (8-13-4), who were swept in the three-game set and have lost 11 in a row at home (0-10-1). They have not won here since a 2-0 victory against the Islanders on Jan. 24.
"It's heartbreaking; I feel for the players," New Jersey coach Lindy Ruff said. "They battled hard. Our goalie battled hard and made some great saves. There's ways that we could have been better, but there's still a lot where I feel the pain the players are going through."
The Devils thought they won the game 27 seconds into overtime when P.K. Subban scored on a slap shot from the top of the left face-off circle, but the goal was overturned after New York coach Barry Trotz successfully challenged for offside.
"You're thinking the game's over, and then they started to take a look at it, and our video guys are calling down saying they're pretty sure it's offside, so it's game-changing," Islanders center Brock Nelson said. "Obviously, it gives us some life. You don't want to take a penalty [in overtime], but the penalty kill did the job, and then [Sorokin] made some big saves. They're not always going to be pretty, but a win is a win."
Oliver Wahlstrom scored the deciding goal on his first NHL shootout attempt in the fourth round. Anthony Beauvillier scored in the third round to extend the shootout.
It was also the first shootout of Sorokin's NHL career.
"After they scored on their first shot of the shootout (by Devils forward Nikita Gusev), I thought [Sorokin] really held fort after that," Trotz said. "I thought that was a really huge goal by [Beauvillier] when the pressure is on. If you don't score, game over [but] you get that goal and keep yourself alive, then 'Wally' getting the winner.
"Not the prettiest ... it was drawn out, the longest 60-minute game we've had in a while, that's for sure."
