Winnipeg's Jeff Stoughton scored a double in the final end to beat Edmonton's Kevin Martin 5-4 on Friday at curling's Players' Championship in Toronto.
Stoughton has won three in a row heading into the playoffs. He lost his opening round-robin match to Regina's Steve Laycock.
Martin tried to score a deuce in the fourth with Stoughton leading 2-1, but after a measurement his rink was only able to claim a single to tie it.
Martin went ahead 3-2 after Stoughton couldn't drag his final shot to the button, giving up a steal of one in the fifth. The teams then traded singles heading into the eighth.
Martin (2-2) now faces defending Players' champion John Epping (2-2) in a tiebreaker.
In other Draw 13 action, Glenn Howard scored a triple in the seventh end to pull ahead and win 5-3 over Winnipeg's Mike McEwen.
