NEW YORK - Brandon Dubinsky and defenceman Dan Girardi scored 2:04 apart during New York's three-goal second period, and Henrik Lundqvist earned his 20th NHL shutout to lift the Rangers to a 3-0 victory.
It sent the New Jersey Devils to a season-high, fifth straight loss Monday night.
Ryan Callahan added his 21st goal for the Rangers, who bounced back from a disappointing 0-1-1 road trip and moved within a point of sixth-place Pittsburgh in the Eastern Conference playoff race.
New York also stretched its lead to four points over Florida, which is below the post-season cutoff.
There was no drama between Rangers agitator Sean Avery and Devils goalie Martin Brodeur, two longtime adversaries.
