TAMPA, Fla. - Martin St. Louis and Teddy Purcell each scored twice, resilient goalie Dwayne Roloson weathered a hat trick by Boston's David Krejci, and the Tampa Bay Lightning stayed alive in the Eastern Conference finals with a 5-4 win over the Boston Bruins in Game 6 on Wednesday night.

Game 7 is Friday night in Boston. The Bruins are seeking their first trip to the Stanley Cup Finals in 21 years, and the Lightning will try to clinch their first appearance on hockey's biggest stage since they won their only NHL championship in 2004.

Canucks back in Finals

VANCOUVER, British Columbia - Vancouver Canucks captain Henrik Sedin didn't hesitate to compare winning Olympic gold to the chance to play for the Stanley Cup.

For Sedin, who won the Olympics with Sweden in 2006, it was just as important to earn a trip to the Cup Finals for the first time in his career.

"It's up there with the Olympic gold," Sedin said. "It's a tough journey to go through to get here. The Olympic medal, it's a short tournament, you play a few games, you get a few bounces, you're there. This is way tougher."

The Canucks certainly didn't make it easy on themselves Tuesday night.

Ryan Kesler tied the game with 13.2 seconds left in regulation, and Roberto Luongo made 54 saves before Kevin Bieksa scored a strange and lucky goal 10 minutes, 18 seconds into the second overtime to send the Canucks to the Finals for the first time since 1994 with a 3-2 win over the San Jose Sharks in Game 5.

Rafalski hangs 'em up

DETROIT - Three-time Stanley Cup winner and two-time Olympic silver medalist Brian Rafalski announced his retirement from the NHL on Wednesday. Rafalski said spending time with his family in good health is more important than the $6 million he would've made next season in the final year of his contract with Detroit.
