Henrik Lundqvist needs help.

Though the Rangers goalie did just about everything possible to send thefirst-round playoff series back to New York tied at one — making 37 saves — the team’s reeling offense couldn’t provide a fraction of his success, allowing the Capitals to secure a 1-0 overtime win in Game 2 yesterday at the Verizon Center.

“[Lundqvist] was unbelievable,” Rangers forward Rick Nash said. “We have to get goals for him. There are no excuses.”

Lundqvist saw and swallowed nearly every puck in sight, putting together a nearly 68-minute compilation of mind-blowing and heart-stopping saves. That was, until Mike Green’s one-timer, on a power play eight minutes into overtime, rocketed past Lundqvist, giving the Capitals a 2-0 lead in the series that shifts to the Garden for Game 3 tomorrow.

“I didn’t pick it up until it hit the post pretty much,” Lundqvist said of Green’s shot. “It’s a tough one. I think both teams played well enough to win this game. ... We have to play even harder, even better, and we need everybody to play their best if we’re gonna beat this team. They’re a good team, no question, but we’re right there.”

While Capitals goalie Braden Holtby did all that was required, earning his first career playoff shutout with 24 saves, Lundqvist earned points on degree of difficulty, which couldn’t be transferred to the scoreboard.

Before making seven saves in overtime, Lundqvist made a key stop to keep the game tied with 9:20 left in regulation, blocking a streaking Jason Chimera’s one-timer, on a pass from Steve Olesky, in front of the net.
