Winning Goal: Brock Nelson’s second goal of the game, at 12:39 of the second period.
Key statistic: The Islanders improved to 12-2 in potential Game 6 clinchers and 8-0 at Nassau Coliseum.
Turning point: Nelson’s first goal, where he stripped Boston D Matt Grzelcyk of the puck and scored on a breakaway to make it 2-1 at 5:20 of the second period and give the Isles the lead for good.
Did you notice? The sellout crowd broke into its first "New York Saints" chant after two penalties were called against the Islanders in the first period, mocking Bruins coach Bruce Cassidy after his assertion of how the Islanders portray themselves.
