UNIONDALE, N.Y. (AP) - Sergei Gonchar scored with 1 minute left for the Ottawa Senators, who netted four goals in the third period and rallied to beat the New York Islanders 5-3 on Tuesday night.
Gonchar's second goal of the season came on a blast from the point to make it 4-3, and Guillaume Latendresse added an empty-net goal to seal the win. Jakob Silfverberg and Zack Smith scored in a 68-second span early in the third period to tie the game after the Islanders led 3-1.
Ottawa has won three straight.
New York's Josh Bailey had scored the go-ahead goal 14 seconds into the second period, and Lubomir Visnovsky extended the Islanders' lead to two goals.
Keith Aucoin appeared to give the Islanders a 4-3 lead at 7:22, but the goal was disallowed because he kicked the puck past goalie Ben Bishop.
Bishop also stopped Aucoin, who scored New York's first goal, on a sharp-angle shot from the left corner late in the third.
It was the second straight game in which the Islanders squandered a third-period lead. They led Florida 3-0 on Saturday before the Panthers tied it. But Casey Cizikas scored the winner for New York with seven minutes left.
Ottawa's Matt Kassian opened the scoring at 6:23 with his first goal of the season and first with the Senators when he redirected Gonchar's slap shot past Nabokov.
Aucoin tied it with a wrist shot past Bishop at 17:53 of the first, netting his fifth goal of the season.
Bailey's third goal, on a backhand that skittered past Bishop, put the Islanders up 2-1. It was the 50th career goal for Bailey, a first-round draft pick by the Islanders in 2008. Visnovsky put the Islanders ahead 3-1 with a power-play goal at 11:46 of the second.
The Islanders began a four-game homestand after road wins over Tampa Bay and Florida. New York is only 5-9-2 at home.
It was the third and final regular season meeting between the clubs. Ottawa won 3-1 at home on Feb. 19, and the Islanders earned a 3-2 shootout win at home on March 3.
The Islanders have been tied or ahead in the third period in 23 of 29 games this season and are 13-7-3 in those contests.
