Robin Lehner made 41 saves and held off a furious late push by New York to lift the Ottawa Senators to a 3-2 victory that prevented the Rangers from clinching an Eastern Conference playoff berth on Saturday night.
The Rangers needed only one point to secure a postseason spot for the fourth straight year, but were shut down by the Senators, who hold only faint playoff chances.
Mark Stone and Mika Zibanejad scored in the first, and Jason Spezza made it 3-1 in the second for Ottawa, which squandered a 3-0 lead in a 7-4 loss to Montreal on Friday.
Mats Zuccarello deflected in two goals in the middle period to bring the Rangers within a goal each time. Henrik Lundqvist made 31 saves in the loss.
