Canada's Rob Armitage is a victory away from locking up a playoff spot at the world senior curling championships.

Armitage, from Red Deer, Alta., improved to 6-0 on Wednesday with a 6-3 win over Denmark's Bent Juul Kristoffersen.

The win moves Armitage's rink of third Keith Glover, second Randy Ponich, lead Wilf Edgar, alternate Lyle Treiber and coach Bill Tschirhart to two wins behind Sweden (8-0) in the 10-team round robin.

Canada plays Sweden on Thursday. A Swedish victory would secure first place and last-rock advantage in Saturday's semifinals. Canada has three round-robin matches remaining, and a victory in any of them would lock up a playoff spot for Armitage.

"I would rather be in first place," said Edgar. "I don't want to go in the playoffs in second place. Let's keep the momentum and don't give anybody a chance. Keep winning, don't let them get any rocks in play, and next time you play them, probably they remember that."

The game against the Danes (5-3) was another example of that. Canada gave up a stolen point in the first, but played air-tight defence the rest of the way, and jumped on Danish miscues to score deuces in the second, fourth and seventh ends, all on draws by Armitage.

"That seems to be the key," said Edgar. "We're keeping things fairly open because we can hit and draw as well as anybody here. We're just trying to get ahead and keep things clean."

On the women's side, Cathy King of St. Albert, Alta., had the day off and takes a 4-0 record into Thursday's match against Austria's Veronika Huber (3-1).

Meanwhile at the world mixed doubles curling championship, Canada's Robert Desjardins and Isabelle Neron defeated Russia's Alexey Kamnev and Yana Nekrasova 8-4.

The duo from Saguenay, Que., improved to 3-3 and remained in playoff contention with the victory at the Grant-Harvey Centre.

"Yes, it's a relief," Neron said. "But we've been saying, 'Let's stop putting pressure on ourselves. Just make shots and have fun out there.' And I think we had a lot more fun today."

Canada is in fifth place in its nine-team pool. Eight of the 27 teams will make the playoffs.

The tournament is being held in conjunction with the world seniors curling championships.
