Final score: Islanders 5, Bruins 4
Winning Goal: Brock Nelson’s slot shot at 1:59 of the third period.
Key statistic: The Islanders averaged 2.71 goals per game in the regular season — 21st in the NHL — but have scored at least four goals in seven of their 11 playoff games.
Turning point: Mathew Barzal’s goal at 18:49 of the first period tied it at 1 after the Bruins dominated the period.
Did you notice? Defenseman Scott Mayfield was furious there was no penalty on Nick Ritchie in the first period after the hulking forward hit Mayfield in the head with his elbow while Mayfield was on a knee on the ice.
Injury report: Bruins defenseman Brandon Carlo remained out for a second game after Cal Clutterbuck’s hit in Game 3 . . . Islanders winger Oliver Wahlstrom (lower body) missed his sixth straight game . . . Bruins defenseman Kevan Miller (undisclosed) remained unavailable.
Other news: Wahlstrom took part in the Islanders’ optional morning skate. He remains day to day . . . Bruins center Patrice Bergeron responded to Islanders coach Barry Trotz calling him a "veteran guy who knows how to cheat on the faceoffs," and saying he was "relying" on the linesmen to "make sure that the cheating doesn’t go on." Bergeron said: "He said it was a veteran play. I think it’s a veteran play by him as a coach to talk to try to get the linesmen and the officiating to think about it." Bergeron was tossed from his first faceoff of the game.
