Instant analysis: Islanders vs. Panthers, Game 5

SUNRISE, Fla. -- Alan Quine scored at 16:00 of the second overtime to give the New York Islanders a 2-1 win against the Florida Panthers in Game 5 of the Eastern Conference First Round Series at BB&T Center on Friday.
Frans Nielsen scored and Thomas Greiss made 47 saves, including a penalty shot in overtime, for the Islanders, who lead the best-of-7 series 3-2.

Aleksander Barkov scored in the third period, and Roberto Luongo made 40 saves for the Panthers.

What we learned:The Panthers again controlled play for much of the game at even strength and were the victims of some brilliant goaltending by Greiss, who lost a shutout when Barkov scored 1:59 into the third period. The Islanders played a disciplined game despite spending so much time in their end, giving the Panthers one power play. Quine ended the game when he scored on New York's second power play of the second overtime.
What this means for Islanders:New York has a 3-2 series lead for the first time since they defeated the Washington Capitals in six games in the opening round of the 1993 Stanley Cup Playoffs. The Islanders are one win away from their first series win since that year, when they defeated the Pittsburgh Penguins to advance to the Wales Conference Final.
What this means for Panthers:Florida, which hasn't won a playoff series since reaching the 1996 Stanley Cup Final, is on the brink of elimination. Forward Vincent Trocheck made his series debut; he had been out since sustaining a foot injury March 29. Forward Jaromir Jagr has gone 36 consecutive Stanley Cup Playoff games without a goal.

Key moment: Greiss kept the Islanders alive 7:19 into overtime when he denied Barkov with a left-pad save on a penalty shot. Barkov was awarded the shot after defenseman Calvin de Haan gloved the puck and tossed it away from the crease.
Unsung player of the game: Islanders coach Jack Capuano on Friday morning said he expected more from his fourth line, and it got the message; center Casey Cizikas won eight of 18 faceoffs and had five hits.
What's next: The series shifts back to Barclays Center in New York for Game 6 on Sunday (7 p.m. ET; NBCSN, CBC, TVA Sports), when the Islanders will try to win a playoff series for the first time in 23 years.
