Carolina has won four straight and six of its past seven playoff games.
"I'm not really surprised by our play because we've been playing playoff hockey the entire second half of the season," Foegele said. "This is a real resilient group, and we keep getting injuries each game, but someone else is stepping up, whether that's blocking shots or contributing in some way. This group's real resilient, and I'm really proud of the group."
Niederreiter said, "We had to stick to the game plan, get pucks to the net and traffic in front of their goalie, and that's exactly what we did,"
Mathew Barzal gave the Islanders a 1-0 lead on a power-play goal 13:17 into the first period. Barzal's attempted pass below the left circle to Josh Bailey deflected off the stick of Hurricanes defenseman Jaccob Slavin. The goal ended Mrazek's shutout streak of 135:04, dating to Game 7 of the first round against the Washington Capitals.
