For a few moments Wednesday morning, it was just Lightning teammates Marty St. Louis and Mike Smith on the ice.

St. Louis had a shootout move he wanted to try. Smith, Tampa Bay's backup goaltender, was, as he called himself, "the guinea pig."

"I was trying to do something a little more fun and not be afraid of not scoring," St. Louis said. "Just go after it."

The dry run worked as St. Louis used a backward backhander to clinch Wednesday night's 4-3 shootout victory over the defending Stanley Cup champion Blackhawks in front of an announced 19,912 at the St. Pete Times Forum.

"Oh, man, it's a huge win," St. Louis said. "We've played some pretty good hockey. We just haven't gotten the results. This time of year, it's all about results."

For the Lightning (38-21-8), it was about breaking a season-high four-game losing streak and staying two points behind the first-place Capitals (who beat the Oilers 5-0) in the Southeast Division.

There was a Steven Stamkos sighting as the right wing scored his league-best 42nd goal, his first in seven games and second in 13. Teddy Purcell scored, and St. Louis got his 25th as Tampa Bay had more than two goals for the first time in seven games.

Dwayne Roloson's stop of Bryan Bickell's breakaway with 1:42 remaining in overtime preserved the tie.
