BUFFALO — A road trip that started on a high ended with a giant splat.

The six-game win streak that saw the Islanders vault themselves back into playoff contention moved well out of sight in the rearview mirror on Thursday with a second straight defeat in disastrous fashion, 4-0 to the Sabres, as the visitors turned in a dilapidated and tired performance at KeyBank Arena.

Instead of taking momentum back home with them, the Islanders are trudging back to New York needing very much to re-find the game they so recently unlocked with just a solitary day off before a matinee back-to-back against Ottawa and the Rangers.

This was a night where pretty much everything that could go wrong did, with the Islanders struggling to put together basic fundamental parts of their game, passing and receiving the puck poorly and looking out-of-sync all night.

Their first shot on goal didn’t come until 10:15 into the game.

Then after recording one 30 seconds into the second period, it took until the 7:20 mark to get their second of the frame.

Shortly after, the train flew right off the tracks.

It looked for a while as though Ilya Sorokin could bail the Islanders out, with the goaltender playing at the top of his game, particularly in a first period where he repeatedly bailed out his teammates.

But just 19 seconds after Anders Lee went off for interference early in the second period, Victor Olofsson found a way past the netminder, beating him with a sharp-angled look from below the right circle.

Just 5:19 later, the rout was on.
