OTTAWA (AP) _ Martin Havlat and the Ottawa Senators turned a slight edge into a victory.
Havlat scored 2:26 into the third period, lifting Ottawa to a 2-1 win over the Calgary Flames on Saturday.
Tied at 1 early in the third, Havlat was ruled onside on a close play at Calgary's blue line as Jason Spezza carried the puck into the zone.
``I had it in front of me and I didn't think it was offside, and the refs didn't call it offside so we just continued to play,'' Spezza said. ``It's a game and the refs are human, and if they did make a mistake, they made a mistake. But to us, it felt like it was onside and I think it was.''
Havlat took Spezza's pass and, with his legs spread wide as he closed in on goalie Roman Turek, reached across to his backhand and lifted a shot over Turek's outstretched pad for his 21st goal.
``I'd like to see the replay to see if it was actually offside because everybody on our bench was yelling, 'It's offside! It's offside!''' Flames center Craig Conroy said. ``We didn't get a break and he buried it.''
The game was the first of an all-Canadian tripleheader broadcast nationally involving each of Canada's six NHL teams. In other games, Toronto hosted Montreal and Vancouver was at Edmonton.
Bryan Smolinski scored a power-play goal in the first and Patrick Lalime made 18 saves for Ottawa, which lost 3-2 to Atlanta in overtime Thursday to end a five-game unbeaten streak.
The Senators are undefeated in regulation in their last eight games (5-0-1-2).
``We knew we were in for a battle but we weren't going to lay down for them, and maybe it was a perfect game for us _ we knew they were going to be in our face and we responded and it's a great two points,'' Smolinski said.
Defenseman Jordan Leopold scored on a power play midway through the first for Calgary, which has lost two in a row on the heels of its third four-game winning streak of the season.
``It was tied going into the third so it was going to come down to one scoring chance,'' Flames coach Darryl Sutter said.
Mike Fisher and Antoine Vermette returned to the Ottawa lineup after lengthy absences due to injury. Fisher, who missed the last 25 games, has appeared in just three games this season because of a right elbow injury. Vermette missed eight games with a shoulder injury.
After Ottawa was called for too many men 8:48 in, Leopold beat Lalime with a wrist shot from the point at 10:26 for his seventh of the season.
Smolinski's 16th goal of the season tied it at 15:25, when he deflected Daniel Alfredsson's point shot over Turek.
Turek, who missed two games for the birth of his child, stopped 22 of 24 shots. He has lost seven of 11 starts _ including four of his last five _ since returning from a knee injury that caused him to miss 39 games.
``I have to find a way to win more games in a row,'' said Turek, who lost the starting job to Miikka Kiprusoff during his absence. ``So far I win one, then lose one, and it's not working. If I play, I have to find a way to put more wins together and go from there.''
