Islanders 3, Senators 2 (OT)
Defenseman Thomas Hickey scored at 3:06 of overtime as New York matched its longest home winning streak in 11 years with its seventh straight victory at Nassau Veterans Memorial Coliseum.
Hickey's wraparound attempt caromed off the skate of Ottawa defenseman Cody Ceci and into the net as the Islanders won for the 12th time in 14 games and remained perfect beyond regulation (8-0-0) this season. Hickey added an assist, Brock Nelson scored a goal and set up another and Ryan Strome also tallied while Jaroslav Halak made 16 saves to win his 10th consecutive start.
Mike Hoffman and Clarke MacArthur scored for the Senators, who have lost five of six (1-4-1) and will host New York on Thursday in the back end of the home-and-home series. Craig Anderson turned aside 25 shots as Ottawa fell to 4-0-2 in its last six visits to Long Island.
Ottawa opened the scoring midway through the first period as Mika Zibanejad sent a pass to the high slot for Hoffman, who unleashed a bullet that beat Halak. The Islanders drew even with 1:34 left in the second on a breakaway goal by Nelson following a misplay by Ceci.
New York missed taking the lead by one-tenth of a second as Casey Cizikas' slap shot got past Anderson and trickled over the goal line just as time expired in the period. The Islanders got that one back 67 seconds into the third, when Strome jammed home Hickey's stuff attempt, but MacArthur supplied the equalizer 10 minutes later by accepting a feed from Mark Stone and chipping a shot past Halak.
