ATLANTA — Dustin Byfuglien scored at 1:30 of overtime to give the Atlanta Thrashers a 2-1 victory over New York on Sunday, extending the Islanders' losing streak to 13 games.

The Islanders have their longest winless streak since playing 14 straight without a win Feb. 13-March 15, 1990. That streak included three ties.

Rick DiPietro, who had allowed 17 goals while losing his last three starts, had 33 saves and held the Thrashers to one goal in regulation. DiPietro couldn't stop the powerful winner by Byfuglien, the playoff star for the Chicago Blackhawks last season who leads the NHL with four winning shots this season.

Ondrej Pavelec stopped 28 shots for Atlanta.

The Islanders have only 12 goals in their last 11 games.

Michael Grabner knocked in a deflection in front of the net with only 13 seconds remaining in the second period to give the Islanders a 1-0 lead.

Nik Antropov's power-play shot from the right circle tied it early in the third period.

Jim Slater was denied on his chance to give Atlanta the lead with 6:17 remaining in regulation. Slater skated behind the net and attempted to score by wrapping his stick around the post, but DiPietro made the stop. A video review confirmed the call on the ice.

New York defenseman Mike Mottau was helped off the ice in the first period after he was hit by a puck, leaving a bad cut above his right eye. Mottau did not return.

NOTES: The Thrashers outshot the Islanders 14-6 in the scoreless first period. ... The Islanders were 0 for 4 on the power play, leaving them 0 for 24 in their last six games.
