WILMINGTON -- While reigning Vezina and Conn Smythe Trophy winner Tim Thomas continues to play at a high level, his backup for the Boston Bruins, Tuukka Rask, has been even better.

In 13 games, Rask (8-4-1) has a 1.61 goals-against average and .945 save percentage, both best in the NHL. He recently had a shutout streak of 170:26 and is riding a four-game winning streak with two shutouts during that stretch.

The situation presents Bruins general manager Peter Chiarelli with a problem any GM would love to have. Thomas, 37 and still at the top of his game (16-6-0, 1.94 GAA, .939 save percentage), is under contract through next season at a salary cap hit of $5 million. Rask, 24, is due to become a restricted free agent July 1; if he continues his stellar play, he rightfully could expect a decent raise from his $1.5 million salary. And who could blame Rask if he preferred to go elsewhere for a chance to be another team's No. 1?

Chiarelli wouldn't comment on negotiations but did say in an email that "Tuukka is a large part of our present and our future."

And that's just fine with Rask, whether he's the starter here or not.

Following practice Tuesday, Rask made it clear he wants to remain with the Bruins for the long haul.

"I think everyone does," Rask told ESPNBoston.com. "I bet a lot of guys want to come and play here as well. We've got a good group of guys here that have been here for a couple of years now and I think that's my goal as well.

"I haven't really put a lot of thought into it, but he's [Thomas] got a year left on his contract and mine is up obviously, but I want to stay here. I'm sure they have a plan for that too and it will all work out good. I'm a young guy and I want to have a long future ahead of me as a Bruin and make more good things happen for the team and our fans."

Rask was asked if he'd be willing to open contract talks now should Chiarelli approach him or his agent?

"Yeah, for sure. Offer me 10 years and a hundred million, I'll take it!" Rask joked.

That positive, easy-going approach is a big factor in Rask's success this season. Instead of letting a contract year serve as a distraction, Rask has used it as motivation.
