Duclair's goal midway through the third pulled Isles within 4-3, but Pageau's apparent tying goal was waved off for goalie interference.

A controversial major penalty assessed to Islanders forward Casey Cizikas led to two Dallas Stars power-play goals in New York's 4-3 loss on Sunday.

This was the return to normal, and with it came the return to normal old controversies, normal old frustrations and normal old losses. The 4 Nations Face-Off, it was not, at UBS Arena on Sunday night.

The New York Islanders (25-24-7) lost their third straight game as the Dallas Stars (37-18-2) utilized a Casey Cizikas major penalty to storm past New York in the second period.

The hat trick was Robertson’s fourth in the NHL. Sam Steel also scored, and Roope Hintz and Matt Duchene each had two assists for the Stars (37-18-2), who have won three straight and eight of 10, including a 4-2 win at the New Jersey Devils on Saturday. Jake Oettinger made 35 saves.

Jason Robertson completed a hat trick within nine minutes of the second period Sunday night for the surging Dallas Stars, who knocked off the New York Islanders 4-3 in Elmont, N.Y.
