Sidney Crosby might be creating an intriguing subplot for the Winter Classic: He's riding one of the NHL's longest scoring streaks in the last 20 seasons. Crosby scored twice during a four-point night to extend his scoring streak to 25 games, and the Pittsburgh Penguins won their final home game before the New Years Day's outdoor game by beating the Atlanta Thrashers 6-3 on Tuesday. Crosby twice answered Thrashers goals by scoring in the first period, then set up Chris Kunitz's goal 9 seconds into the third period and another by Matt Cooke. Craig Adams also scored short-handed for Pittsburgh, which has won 16 of 19. Crosby will try to extend his streak against the New York Islanders on Wednesday night, Pittsburgh's final game before the Classic. The only longer streak over the last two decades was Mats Sundin's 30-game run for Quebec in 1992-93. Read more: http://sports.espn.go.com/nhl/recap?gameId=301228016
