Playing without superstar Artemi Panarin in the lineup, the Rangers fell to the Islanders 4-2 on Tuesday night at Madison Garden.
Panarin has missed two Rangers' practices recently with what's being described as an upper-body injury, and he was announced as a scratch shortly before Tuesday's game.
Playing in his first season with the Blueshirts, Panarin ranks fifth in the NHL with 68 points, including 26 goals.
With the loss, the Rangers will take a 23-21-4 record into the All-Star break, while the Islanders finish the first half with a record of 29-15-5.
The Rangers outshot the Islanders 42-18 on the night, but the Islanders were able to able to jump out to a two-goal lead in the first period, as Josh Bailey scored his 11th of the season, and Anthony Beauvillier followed that up with his 13th of the season.
In the second period, Anders Lee added to the Islanders' lead with his 16th of the season to put the Islanders up 3-0.
After Brock Nelson's 20th goal of the season gave the Islanders a commanding four-goal lead, the Rangers chipped away with two goals in the final six and a half minutes from Pavel Buchnevich and Chris Kreider, but ultimately it wasn't enough.
Rangers goalie Alexandar Georgiev stopped just 14 of 18 shots that came his way.
