Being shutout for the first time since opening night, dead legs and the league's best goalie stopped the Devils, Monday night.
Rangers goalie Henrik Lundqvist earned his NHL-leading 8th shutout of the season, and made only 13 saves in the win for New York, who has lead in the Eastern Conference for seemingly the entire season.
The Devils were playing their third game in four days -- all losses -- and managed just three shots in the third period.
New Jersey had their chances, but the troubles came early and often in the second period, where one of their top goal-scorers, David Clarkson, sat in the box for 19 minutes, keeping the Devils on the penalty kill.
Rookie of the year candidate Adam Henrique hit the post in the first period, and forward Ilya Kovalchuk had impressive moments later in the game, but the Devils struggled overall, appearing to be tired from their recently busy schedule.
Patrik Elias was given a prime opportunity for a goal in the second period when he intercepted a pass below the slot, but dumped the puck off for no one instead of taking the shot that could have tied the game.
The Rangers got a goal late in the first period when Carl Hagelin slipped a shot behind Martin Brodeur's pads after the Devils had won the majority of the period.
The third straight loss keeps New Jersey in sixth place in the Eastern conference, and although that isn't the worst place to be, the seventh and eighth spots are closely creeping up on them with 20 games remaining.
Overall, the Devils have been strong since the all-star break with a 9-4-1 mark, but that number is sliding away with their recent play.
New Jersey lost to the Canucks, 2-1 on Friday, the Lightning, 4-3 on Saturday and 2-0 to the Rangers on Monday.
New Jersey will be on the road to take on Bruins, Capitals and Islanders over the next six days, before hosting the Rangers back at Prudential Center on Mar. 6.
