Through 17 minutes in the second period, the Isles held the Capitals to only three shots on goal in the period. The Caps made a push in the final few minutes of the middle frame, but Varlamov made a tremendous glove save on a long-distance blast from Alexander Ovechkin with 25.7 seconds left in the period.
Down by two goals and on the brink of elimination, the Caps played with a push and a shooting mentality in the final 20 minutes of their season.
The Caps tested Varlamov, but the Isles netminder didn't waver. Varlamov flashed leather on Backstrom, who fired a far-sided one-timer 1:22 into the third period. Through the latter half of the third period, both teams' offenses were stifled and unable to generate much.
The Islanders played a suffocating and detailed game in a determined fashion. As the clock was approaching expiration, the Capitals pulled Holtby from between the pipes in place of an extra skater.
"When we're playing the right way you can feel it on the bench," Bailey said. "It's contagious."
The Islanders cushioned their lead with two empty-net goals to diminish the Caps' hope of surviving one more game. Leddy scored his second of the postseason with 2:47 remaining in the game and Bailey buried the dagger with 1:29 left on the clock.
