It may very well be the moment Devils rookie defenseman Eric Gelinas went from being an impressive young prospect to a dynamic NHL star.

That’s what an overtime goal against the Rangers can do.

“The way he plays, he might be a superstar in this league if he keeps working,” winger Jaromir Jagr said.

Gelinas, 22, was modest about the booming one-timer which went past goalie Henrik Lundqvist at 1:15 of overtime, giving the Devils a 4-3 victory over the Rangers Saturday night at Madison Square Garden.

But the triumph was big in several ways.

* The Devils have won all three games against the Rangers this season, with their next showdown coming outdoors in Yankee Stadium on Jan. 26.

* A team running on fumes, playing its sixth game in nine days, refused to pack it in after falling behind, 2-0, and pulled off a memorable comeback.

* And in Gelinas, called up from Albany (AHL) on Oct. 23, the Devils have found a dangerous power play point man.

“That’s an asset we have that we really never had before,” goalie Martin Brodeur said.

After battling back to tie the game on goals from Cam Janssen and Travis Zajac, the Devils took a 3-2 lead when Michael Ryder scored at 15:56 of the third period.

Ryder skated past Rangers defenseman John Moore and his shot from th right circle went through Lundqvist. It was Ryder’s third goal in four games after failing to score in 11 straight.

With a victory within the Devils’ grasp, Zajac shot the puck over the glass with 1:11 left in regulation time to give the Rangers a power play. When Lundqvist left for an extra skater, it gave the Rangers a two-man advantage.
