The team said Tuesday that Tlusty agreed to a deal that will pay him $1.5 million next season and $1.7 million in 2013-14.
The 24-year-old forward had career highs this season with 79 games, 17 goals, 19 assists and 36 points. He could have become a restricted free agent July 1, meaning the team had the right to match any offers he received.
General manager Jim Rutherford says Tlusty "showed that he can contribute as a top-end NHL forward."
It's cool when you think about how many great American players have played the game and the two players that were at that 18-game point streak and what they've done in their careers. It's pretty cool right now, but it was kind of overshadowed by the loss.
