The Islanders got into penalty trouble to start the second period, racking up eight penalty minutes in just over half of the period. The shorthanded unit held strong going 5-for-5 on the night, but offered the Islanders limited chances in the offensive zone to close the two-goal gap.
"You give a team like that that many power plays in three games, they are going to feel really good about handling the puck," Cal Clutterbuck said. "Whether they're scoring on their power plays or not, the confidence translates."
As the period wore on, the Lightning's chances turned into goals, with Nikita Kucherov and Vladislav Namestnikov each burying a backdoor feed to make it 4-0 Bolts before the end of the second period.
The Islanders outshot the Lightning 20-4 in the third period, but could not bust Vasilevskiy's shutout.
"You just keep going, keep working, keep trying to find your way out of it," Tavares said. "Obviously we don't want to be in the spot that we're in, but we're not going to quit, we just have to stay positive and stay together. All you can do is get up tomorrow and find a way to get better, work yourself through it."
The Islanders have three days off until they host the Pittsburgh Penguins on Friday night. Puck drop is at 7 p.m.
