The New York Islanders are on the cusp of just their second playoff series win in more than a quarter-century.
Jordan Eberle scored for the third straight game, Robin Lehner stopped 25 shots and the Islanders rolled to a 4-1 victory over the stunned Pittsburgh Penguins on Sunday to take a 3-0 lead in their best-of-seven Eastern Conference quarterfinal.
Brock Nelson added his second goal of the playoffs and Leo Komarov scored the first postseason goal of his career for the Islanders, who have pushed the star-laden Penguins to the brink of elimination.
Garrett Wilson scored Pittsburgh's lone goal, a first-period deflection past Lehner that gave the Penguins just their second lead of the series.
It didn't last. Eberle tied it 28 seconds later and Nelson's wrist shot put New York in front to stay just 1:02 after Eberle's third playoff goal in as many games.
Komarov's third-period goal gave the Islanders more than enough breathing room, and Anders Lee put the Penguins away with an empty-net goal with 1:28 remaining.
Matt Murray finished with 32 saves for the Penguins, but Pittsburgh again struggled to generate any sort of offensive momentum against the Islanders. New York, which allowed an NHL-low 196 goals during the regular season, has surrendered just five in three games.
Pittsburgh needs a win in Game 4 on Tuesday to avoid being swept for the first time since the 2013 Eastern Conference finals against Boston.
