Norway's Thomas Ulsrud stayed in contention for a world curling championship with a 7-2 win over Sweden's Niklas Edin in a playoff game Saturday.

Ulsrud, winner of the Olympic silver medal last year, was to face Scotland's Tom Brewster in the semifinal later Saturday in Regina. The semifinal winner takes on Canada's Jeff Stoughton in the gold-medal game Sunday.

Stoughton defeated Scotland 5-2 in a playoff between the top two seeds Friday to earn the day off Saturday.

The Norwegians lost four of their first six games to start the Ford World Curling Championship, but then won seven in a row, including a tiebreaker game, to reach the semifinal.

"We're looking good right now," Ulsrud said.

Canada missed a chance to eliminate Norway from playoff contention in the final round-robin game Thursday. Stoughton was heavy with his final draw to give up the steal and the win.

"The big break for us was Jeff's draw," Ulsrud said. "He's going to make that 95 out of 100. That just gave us an extra boost and since then, we haven't looked back."

Sweden had costly misses early as Norway scored three in the second end and then stole four points over the next three ends.

The win out of reach after six, the Swedes decided it was time to entertain the spectators. Third Sebastien Kraupp delivered his last two stones in a shoot-the-duck position and Edin executed a 360-degree spin out of the hack on his last throw before shaking hands.

The Swedes will play for the bronze medal Sunday against the loser of the semifinal.
