Calgary captain Jarome Iginla became the all-time franchise leader in points on Sunday, but the Flames lost at home 8-6 to the Tampa Bay Lightning.
Iginla scored twice, including his 400th career goal, and drew three assists.
Iginla now has 834 points for the franchise record, four more than Theo Fleury recorded. He was already the franchise leader in goals and games played (922) heading into the contest.
But Tampa Bay capitalized on a spate of Calgary defensive breakdowns and penalties, as well as a subpar effort from Flames goalie Miikka Kiprusoff, to earn the win.
"It's a wake-up call for us," said Craig Conroy. "If we try to run and gun, that's not the way we're going to win games."
Kiprusoff stopped 14 of 19 shots before being replaced by Curtis McElhinney.
Mike Cammalleri had a goal and two assists for Calgary (38-18-6), while Conroy scored and assisted. Jamie Lundmark and Todd Bertuzzi also found the mark.
The Flames will begin a seven-game road trip Tuesday in Ottawa.
Vincent Lecavalier and Martin St. Louis each scored twice and added an assist for Tampa Bay (20-31-12). Evgeny Artyukhin, Vinny Prospal, Steve Stamkos and Ryan Malone also scored.
Veteran Mark Recchi, whose name has figured in trade rumours, recorded a whopping five assists. He moved past Bryan Trottier into 14th on the NHL's all-time scoring list with 1,426 points (535 goals, 891 assists).
Rookie goalie Mike McKenna stopped 34 shots in net.
Each team potted three power-play goals.
"That was right out of the '80s," said St. Louis. "A wide open game, a lot of goals, everybody got involved — it was a fun game to play."
Not long after David Moss missed a chance on the doorstep, Artyukin picked up a puck that Cory Sarich couldn't control and fired a shot from the slot at the 11:07 mark. It was the forward's first goal in 18 games.
Calgary replied just over four minutes later on the power play in a scramble, with Iginla finding the loose puck and putting it past McKenna.
St. Louis would score the first of seven goals in the middle period when he blasted a slapshot from the right circle through traffic past Kiprusoff for a power-play tally.
Conroy tipped Dion Phaneuf's shot to tie it, with Iginla setting the franchise record with an assist and drawing an ovation from the crowd.
"I was excited to get it at home," said Iginla. "I wasn't too picky about it being a real nice one. It was cool to get it on Conroy's.
"Unfortunately the night didn't go the way we wanted, we let it get away from us. Looking back on it down the road, it's still going to be a great night."
At the 13:17 mark, he factored in on Cammalleri's goal from the doorstep, and the Flames appeared on their way when Lundmark scored his second of the season 77 seconds later.
Tampa would take a 5-4 lead by the end of the period with three goals in a 3:30 span. Lecavalier cashed in a play started by defenceman Cory Murphy, Stamkos re-directed Recchi's pass from the corner, and Prospal roofed the puck over Kiprusoff after a no-look pass from Gary Roberts.
Iginla one-timed a Conroy pass to get Calgary back on even terms early in the third for his 400th, but that was as good as it got for the Flames.
McElhinney's pad save on Recchi went right to Malone for his 22nd at the 2:39 mark, a power-play goal.
Lecavalier also scored on the man advantage at 8:32 on a slapshot from the right circle to give the Lightning their first two-goal lead.
Bertuzzi converted Iginla's fifth point from a scramble to draw Calgary close, but St. Louis scored his 22nd into an empty net.
Iginla now has six goals and seven assists in his last six games.
The teams were meeting for the third time since the 2004 Stanley Cup final. The last contest was also a high-scoring affair, won 9-6 by Calgary last season.
