TAMPA, Fla. -- The struggling St. Louis Blues keep finding ways to lose.

John Grahame tied a Lightning record with his eighth consecutive win, and Martin St. Louis scored a tiebreaking goal with 6:30 left in Tampa Bay's 5-4 victory against the Blues on Thursday night.

Grahame made 18 saves in equaling the top Tampa Bay winning streak set by Nikolai Khabibulin in 2004. Ruslan Fedotenko had two goals, including an empty-netter with 33.5 seconds remaining.

Mike Sillinger and Keith Tkachuk each had two goals and an assist for the Blues, who have lost five of six and have the NHL's worst record (5-17-3). Tkachuk got the Blues within 5-4 with 18 seconds remaining.

"We had them down 3-1 ... we can't be scared to make the next play," Sillinger said. "It's almost like we're afraid of success. You've got to know how to win. You've got to want it."

The Blues (2-4-2) have lost six of eight when leading after two periods.

Tim Taylor and Fredrik Modin also scored for Tampa Bay, which has won 9 of 11.
