Uniondale, NY (Sports Network) - Jack Hillen scored the game-deciding goal early in the third period as the New York Islanders tallied three times in the final stanza to dump Boston, 4-2, at Nassau Coliseum.
Matt Moulson and P.A. Parenteau each posted a goal and one assist for the Islanders, who have won four of their last five.
Al Montoya stopped 26-of-28 shots, improving to 7-2-2 on the year.
Nathan Horton and Zdeno Chara provided the offense for the Bruins, who have dropped four in a row. Tim Thomas allowed three goals on 41 shots for his third loss in as many starts.
The Islanders drew even at 1:28 of the third period when Michael Grabner's prayer of a turnaround shot from the right circle slid through Thomas and in, then the home team forged ahead for the first time in the contest when a Hillen point shot caromed off a Bruin in the slot and popped over Thomas at 5:58.
Boston decided to skate with a extra attacker for the final minute of regulation, but the move backfired in rare fashion.
With just under 10 seconds remaining, Parenteau was taken down in the neutral zone by Bruins forward Patrice Bergeron with a clear path to the empty net, meaning an automatic goal was awarded.
Boston got on the board at the 16:29 mark of the first period, when Horton followed up Milan Lucic's rebound and hit the open net with a backhander.
Chara ripped home a shot from the right wing during a two-man edge and the Bruins went up 2-0 at 13:02 of the second, but the Islanders survived the back end of the one-man power play unscathed.
New York cut into its deficit on Moulson's power-play score with two seconds left before intermission.
For the Islanders, it was their first home win against Boston since December 12, 2009...Bruins second-overall pick Tyler Seguin was a healthy scratch once again...Kyle Okposo tallied two assists for the Islanders, and David Krejci picked up two helpers for the Bruins.
