The Atlanta Thrashers announced on Wednesday the signing of defenceman Tobias Enstrom to a new four-year deal.

Entering his sophomore NHL season Enstrom has one year remaining on his existing deal. Financial details were not released for the new contract.

"I think it sends a lot of messages for our fans and for our players," said Thrashers general manager Don Waddell. "It shows the commitment that not only the owners but the franchise is making to one of our young players. We talked about keeping our young players and keeping them long-term, and this is a big step towards that."

Enstrom, 23, was the biggest rookie surprise in the league last year. He appeared in all 82 games, scoring five goals and adding 33 assists, with a minus-5 rating. He regularly logged over 24 minutes of ice time per game for Atlanta.

"I really like it here," Enstrom said. "This is the team who drafted me a couple of years ago. I really want to be a part of something good coming up here.

"Last year we missed the playoffs and hopefully we can get the team going and make the playoffs this year and keep it up."

Atlanta selected the Nordingra, Sweden, native in the eighth round of the 2003 draft.

He spent five seasons in the Swedish Elite League before joining the Thrashers and has represented his native country three times at the world junior and senior hockey championships.
