Atlanta, GA--For a team on the precipice of playoff contention, the Islanders delivered an eyesore of a performance last night at Philips Arena, where they were pounded 6-3 by the Thrashers.

Entering last night’s game only five points out of eighth place in the Eastern Conference, the Islanders sputtered to allow even more separation between them and the last playoff spot up for grabs.

In a performance marred by sloppy play and numerous turnovers, The Islanders suffered from a costly first period, during which they gave up four goals despite out-shooting the Thrashers 21-10.

“In the first period, all their scoring chances came from things we did. Bad turnovers, bad line changes,” coach Scott Gordon said. “No team can live with those mistakes.”

Nik Antropov finished with two goals and Atlanta’s two trade-deadline acquisitions--Clarke MacArthur and Evgeny Artyukhin—both scored their first goals as Thrashers.

“They took advantage of our mistakes,” said defenseman Mark Streit. “They’re fast, they’re skilled and they took scored when they had chances.”

Atlanta scored three goals on their first seven shots before goaltender Dwayne Roloson was pulled and replaced by Martin Biron. Biron didn’t fare much better, giving up three goals of his own over the remainder of the game, but neither netminder got much help with the gallery of gaffes in front of them.

With less than 17 seconds remaining in the first, Streit made a dent in Atlanta’s 4-0 lead with a slapshot from inside the blue line at 19:43 for the Islanders first power-play goal in five games.

The Islanders did not score again, however, until the third period, when the damage was done and the deficit too steep.

A power-play goal from Rob Schremp at 11:38 and a spinning, turnaround strike from Tim Jackman 1:10 later cut the Thrashers lead in half but the effort fell short of a legitimate comeback attempt.

Worsening the blow of last night’s defeat was the team’s inability to build on a spirited 5-3 win against Chicago Tuesday.

“I hope this is a wake-up call for everyone because we were only five points out and there isn’t much time left,” Biron said. “No one can point the finger at anyone tonight. It was everybody.”
