Defending champions Sweden and Canada have qualified for the World Men's Curling Championship playoffs after they both secured an eighth win of the competition in Las Vegas.

The crucial victories came in the evening session where the Swedes recorded a 5-3 win against the United States and Canada defeated South Korea 10-2 in Orleans Arena.

In the morning session, the Swedes swept away Scotland, cruising to an 8-2 win, while Canada suffered a shock 10-6 loss to the US hosts.

Despite that defeat, Canada remain top of the standings with two losses.

Sweden sit second having played and lost a game more.

Skip Niklas Edin was once again a key factor behind Sweden's success, this time playing an influential role in the close match against the US.

In the closing stages of the fifth end, Edin placed a stone on the button to score a point to hand his team a 2-1 lead.

However, neither side could grab control of the fixture and it eventually went down to the wire.

With the score tied at 3-3, Edin had the final stone to win the game, which he did unmistakably, scoring two points.

"It's nice that we’ve qualified," Edin said. 

"It's been tricky - all the teams are trying to figure out the ice, but it’s been different on every draw.

"We have a really high level here, so it’s just trying not to miss too much and making the key shots."

In the fixture against South Korea, the Canadians flew out to a 6-0 lead after skip Brad Gushue scored three in the first end and South Korea’s fourth player Kim Soo-hyuk made a crucial mistake in the second.

Kim’s stone hit another at the front of the house as it made its way down the ice, causing South Korea to give up three points.

In the fifth end, with the score at 7-1, Canada scored another three points to put the match out of sight.

After South Korea added a point in the sixth, the two teams shook hands to confirm Canada’s empathic win.

"It was a discouraging loss earlier, but the US just really out-curled us," Gushue said.

"So, to come back and play the way we did, especially the first end - we played eight great shots and got a three on the board - was good.

"We got fortunate in the second end and got a steal of three and from then on it was in our hands."

The round-robin phase ends tomorrow and plenty of teams are still in contention for qualification.

Italy, Scotland, Switzerland and the US are tied for third with each team having six wins and four losses.

The Italians recorded an automatic victory against Switzerland after the Swiss were forced to forfeit.

Swiss skip Yannick Schwaller ran out of time readying to throw the last stone in the ninth end, handy Italy the win.

Italy also beat the Czech Republic 6-5 while the Switzerland bounced back to overcome South Korea 9-7.

Scotland suffered a shock 5-4 defeat to The Netherlands, who are last in the standings.

Norway experienced a mixed day, winning 10-6 win against Denmark and losing 10-6 versus Germany.

Other matches saw the Czechs defeat Finland 10-4 and Denmark beat the Dutch 7-2.
