Only one unbeaten team remains at the 2008 World Men's Curling Championship.

Canada's Kevin Martin moved to 4-0 with an 8-2 win over France and Germany's Andy Kapp dropped his first game, to Australia, by a 5-3 count to fall to 4-1.

Meanwhile, China cashed their second win of the tournament with an 8-5 victory over Denmark, and Switzerland finally scored a win, taking a tight battle over Sweden by a 5-4 scoreline.

Kapp brought in alternate Felix Schulze as his next two matches are against Norway and powerful Canada. The 27-year-old fired an 88 in shooting percentage but it wasn't enough as the Germans dropped two deuces while scoring only singles.

"I feel worse because of my playing," said Kapp.

"My team played really well and I did not."
