Edmonton's Kevin Martin and Sweden's Niklas Edin will clash in the final at the GP Car and Home Players' Championship.
Martin delivered a careful bump into a crowded house to score two and defeat city rival Kevin Koe 7-6 on Saturday, while Edin survived a stolen 10th end to defeat Glenn Howard of Coldwater, Ont., 5-4 to also book a place in Sunday's final.
Koe, the 2010 world men's champion, fought back from deficits of 2-0 and 4-1 and held a 6-5 lead into the 10th end.
It appeared that Martin's outrageous record of 74 wins and only one loss when scoring two in the first end might need an adjustment.
But Koe was low on his time clock and rushed his final stone with two seconds remaining, leaving Martin with the delicate tap for the win.
Meanwhile, Edin's world bronze medallists held a 2-0 lead at the halfway mark and missed a shot for the win in the 10th before scoring their single in the 11th for a 5-4 win. Howard elected to force the hard-hitting Swedes to draw against three counters for the win, and Edin used his brushers well and made no mistake.
Edin, who finished fourth at the 2010 Olympics, are the first international team to win the championship final of a Capital One Grand Slam of Curling event.
Watching with interest was Winnipeg's Mike McEwen team. Losses by both Martin and Howard would keep their hopes for the top prize in the Capital One Cup alive, but the mixed result still guarantees them second place money worth $25,000. Martin clinched the Cup and its $50,000 top prize, while Howard earns third-place money of $10,000
A further $41,000 is available in Sunday's final.
Koe's loss marked the end of his squad, as third Blake MacDonald has announced his retirement. Regina skip Pat Simmons has already been confirmed as MacDonald's replacement.
Saturday began with men's C-qualifiers and women's semifinals and included a miraculous game-winning shot from McEwen and a bizarre injury to Brandon, Man., skip Rob Fowler, who finished his game with a separated shoulder.
The women's final saw Winnipeg's Jennifer Jones defeat Ottawa's Rachel Homan 7-5. The victory gave Jones, Kaitlyn Lawes, Jill Officer and Dawn Askin the $25,000 winner's cheque to conclude their World Curling Tour season winnings at $76,000. In addition, Jones claimed another $50,000 for the top prize in the women's Capital One Cup.
In the men's quarter, the injured Fowler was replaced by World Curling Tour president Pierre Charette of Gatineau, Que. The seven-time Brier competitor called the game and threw lead stones in a 6-5 loss. In another quarter-final matchup, Koe looked to have missed his last shot against Winnipeg's Jeff Stoughton but the stone caught a piece of debris and slowed, settling into the scoring area for the 5-4 win.
"That's just the rub of the game," said Stoughton, who won the world championship last weekend. "They take it, and we get to go home. But we missed too many opportunities to score two.
"It's been an amazing couple of months, the whole season has been awesome. The team just pulled everything together and it's been wonderful."
