After six successive wins, Canada’s perfect record was ended when they lost 7-5 to defending world and Olympic champions Sweden at Orleans Arena in Nevada.

With the scores level at 5-5 in the final end, Canada skip Brad Gushue came up short with his last draw attempt before Sweden’s Niklas Edin clinched two points to secure the win.

Despite the blow, Canada responded well as they produced a strong second-half performance to defeat Finland 8-3, scoring two points in each of the sixth and ninth ends.

"It’s very important to come back with a win after a tough game against Niklas, and to go 7-1 feels good," said Gushue.

"I thought we played pretty solid.

"They play an interesting style which caught me off guard a couple of times and made it challenging for us, so very smart of them.

"We try to play it simple and leave ourselves a shot.

"If we score two and threes, then that's a bonus."

Sweden would have been hoping to kick on after their victory over Canada but were brought back to earth by South Korea.

Edin scored two points with a draw to go into the break with a 4-3 lead.

In the eighth end, with the game level at 4-4, Edin came up short with his final draw to only register one point instead of making a multiple score.

The Koreans took advantage of that mistake and went on to win by 7-5 with a single steal in the 10th end.

It was a second successive triumph for South Korea who thumped Italy 10-5 earlier in the day.

The morning session also saw victories for Switzerland and the United States who defeated Denmark 7-0 and The Netherlands 8-3, respectively.

The US enjoyed further success when they overcame Switzerland 7-4 courtesy of a fine showing from skip Korey Dropkin.

"Our front end have been incredible all week," said Dropkin on the performance of his team, who have won five of their eight matches to sit in joint fourth position alongside South Korea and Switzerland.

"They’ve been making so many shots, dragging rocks and it makes such a difference having incredible sweepers.  

"I’ve been struggling a little bit this week, but they’ve been super supportive."

Scotland are Canada’s closest challengers having improved their record to six wins and two losses with an impressive 6-0 win over the Czech Republic.

"All we’re focussing on is turning up and beating whoever's playing us," said Scotland skip Kyle Waddell.

"We’re looking forward to the rest of the games now.

"If the boys play like that there’s no reason why we can't beat anybody."

Norway edged Finland 5-4 before the Czech Republic overcame The Netherlands 11-5 and Germany downed Denmark 10-7 in the final session of the day.

Competition is due to continue tomorrow with more round-robin matches.
