DETROIT The Calgary Flames proved there's more to their offense than Jarome Iginla.
Marcus Nilson's first career playoff goal at 2:39 of overtime lifted Calgary to a 2-1 victory over the Detroit Red Wings on Thursday night in Game 1 of their Western Conference semifinal series.
Calgary's Robyn Regehr, who like Nilson played in his eighth postseason game, scored his first career playoff goal late in the second period to tie it at 1.
Iginla, a finalist for NHL MVP, didn't mind being held to just two shots both in the second period.

''That's part of what's been so fun this year,'' he said. ''It's been somebody different scoring big goals each night. That's why we're where we're at.''
Goaltender Miikka Kiprusoff is a big reason the Flames are in the second round for the first time since winning the Stanley Cup in 1989. And he helped them win their first Game 1 since the finals 15 years ago. Calgary was 0-7 in series openers since.
Kiprusoff's 28 saves lifted the Flames to their fourth straight road victory in the playoffs.
''It's huge,'' Kiprusoff said. ''We're playing the Detroit Red Wings.''
Curtis Joseph made 16 saves for Detroit, which was 3-0 at home this postseason.
On the winning goal, Martin Gelinas passed the puck from behind the net to Nilson, whose shot from the left circle got past Joseph's glove.
''He made a good shot,'' he said. ''I wish I would've had it.''
Game 2 in the best-of-seven series is Saturday in Detroit.
The Flames played their third straight overtime game. Calgary beat Vancouver in overtime in Game 7 of the first-round series after losing Game 6 in triple overtime. Detroit played its first overtime of the postseason after getting past Nashville in six games.

PHILADELPHIA Marcus Ragnarsson scored the go-ahead goal in the second period, leading the Philadelphia to a victory over Toronto in Game 1 of their Eastern Conference semifinal series Thursday night.

Tony Amonte and Simon Gagne also scored for Philadelphia. Alexander Mogilny scored for Toronto.
Robert Esche had 22 saves and outplayed Ed Belfour, who stopped 23 shots in a subpar performance.

Sharks 5, Avalanche 2
SAN JOSE, Calif. Patrick Marleau had his second three-goal game of the postseason, and San Jose scored three first-period goals in defeating the Colorado Avalanche in the opener of their second-round playoff series.
Marleau took over the NHL's postseason goal-scoring lead during San Jose's relentless offensive performance for nearly two periods.
He scored San Jose's opening goal and added two more in 94 seconds midway through the second, chasing shaky Colorado goalie David Aebischer.
Vincent Damphousse and Scott Hannan also scored during the first period, which the Sharks dominated with a 79-44 goal advantage during the regular season. Rookie Niko Dimitrakos had three assists, and Evgeni Nabokov made 26 saves.
Game 2 is Saturday in San Jose.
Steve Konowalchuk and Peter Forsberg scored power-play goals for the Avalanche.
