It was only appropriate that a game featuring the NHL's two best overtime teams wasn't settled in regulation.
"He does have a lot of moves in his bag and sure it was a nice goal but it was a bad read on my part," Brathwaite said. "I should have come out and made him make a move."
The win moved the Blues past the Detroit Red Wings into first place in the Western Conference.
"We let a couple goals in at the end and we have to learn from these kinds of mistakes, but we won in overtime and that's most important," Demitra said.
The late-game excitement overshadowed a solid performance from St. Louis center Marty Reasoner, who scored twice in his first game filling in for the injured Pierre Turgeon.
Reasoner was recalled from Worcester of the AHL on Monday. Scott Pellerin also scored for St. Louis and Demitra extended his point-soring streak to seven games (4-5-9).
The loss, Calgary's fourth in a row, snapped a seven-game home winning streak. It was just the Flames second loss at the Canadian Airlines Saddledome since Nov. 13 (13-2-1).
"We need to be better prepared to start the game," Flames winger Rene Corbet said. "We gave up too many scoring chances early and it cost us the game. If we always have to come back and come back like this at the end, we're going to run out of gas."
Trailing 4-2, Calgary pulled within a goal when Bure scored his 27th from a scramble at 15:12.
Bure's 27 goals are a career high, surpassing the 26 he scored last season.
