The Penguins led 6-0 after the second period. They are the first team to win an NHL game being outscored by five goals in the third period; it had never been done in 270 regular-season games or nine playoff games.
"Well, I've never been through an experience like that," Sullivan said. "It's not an easy one to react to. I'm not sure I have a valid answer for you, and that's what I told the players. … We need to be a whole lot better in a lot of areas to close out games."
Scott Wedgewood allowed four goals on 13 shots before being pulled after the first period for the Devils (14-25-6), who were eliminated from playoff contention with a seventh straight loss despite scoring six third-period goals. Aaron Dell made 16 saves in relief.
Devils goalie Mackenzie Blackwood was unavailable because of an upper-body injury.
"Here's what we need, to start it off, we need better goaltending," New Jersey coach Lindy Ruff said. "Flat-out, need better goaltending. We've made some mistakes. Every team makes some mistakes. You've seen some of the goals that went in. Those are saves that need to be made. ... At the end of the day, I need my guys between the pipes to be the difference for us."
The teams will play the second of a three-game set here Thursday.
