Three unanswered goals in the third period sent the Lightning to a 5-1 defeat to the Islanders at Amalie Arena on Monday night.
After a scoreless opening period, the Islanders caught the Bolts out of position in transition on two occasions in the second frame to build their lead.
After Semyon Varlamov stopped Cory Conacher on a breakaway at one end of the ice, the Islanders' Ross Johnston fired home a shot from the right circle as the Bolts struggled to get back defensively. Less than two minutes later, Josh Bailey capitalized on four Lightning players jumping up on the rush and scored on a shorthanded breakaway.
The Bolts got one back late in the period on Steven Stamkos' 10th goal of the year. Stamkos worked his way open at the far post and scored on his backhand while falling to the ice to make it 2-1 through 40 minutes.

Brock Nelson extended the Islanders' lead to two midway through the third period, cleaning up his own rebound after a turnover behind the Lightning net.
Victor Hedman scored minutes later to get the Lightning back within a goal but video review revealed that Anthony Cirelli had entered the zone ahead of the puck and the goal was disallowed.
Nelson added his second goal of the game with just over five minutes remaining and Anders Lee scored on a power play late to put the game away.
Special teams proved to be the Lightning's unpinning on Monday. The Bolts were 0-for-3 on the power play, while the Islanders scored goals on the power play and shorthanded.
The Bolts are back in action tomorrow against the Panthers in Sunrise.
