Japan were the only team to switch up their pairings on Friday, having lost to Thailand on day one.

But it didn't help as Lee and Kyriacou combined successfully again to down Nasa Hataoka and Ayaka Furue 2-up in cold, blustery conditions at Harding Park in San Francisco.

Teammates Hannah Green and Sarah Kemp tied their match with Yuka Saso and Hinako Shibuno.

Having won both matches against South Korea on Thursday, the Australians' effort was enough to guarantee they will advance to the semis from four teams in Pool B along with leaders Thailand with one day of pool matches still to be played.

They face sixth-seed Thailand on Saturday in a contest to decide who they will face in the final four.

Thailand made it a perfect four match victories as the sister tandem of Ariya and Moriya Jutanugarn beat South Korea's Hye-Jin Choi and In Gee Chun 2&1, and Patty Tavatanakit and Atthaya Thitikul taking care of Jin Young Ko and Hyo Joo Kim 3&2.

In Pool A, Sweden's pairings – Anna Nordqvist/Caroline Hedwall and Madelene Sagstrom/Maja Stark – locked in their semi spot with a perfect four-point total by winning both matches against China.

"I was uncomfortably cold when we got to 11 and 12, but was trying to do these little jumps and stuff. But we're not used to this. We'd prefer the sun to come out tomorrow." - Sarah Kemp.

Top-seeds the United States have three points after two days in and will clinch the final spot in Sunday's knockout round by getting at least half a point on Saturday against Sweden or if China don't sweep England.

Lexi Thompson sealed the final US match of the day when she holed a birdie putt from about 12 feet on the 16th hole to give her and Danielle Kang a 3&2 victory over England's Bronte Law and Jodi Ewart Shadoff.

Nelly Korda and Lilia Vu won for the second straight day, beating Alice Hewson and Liz Young 2&1.

The toughest part for the Australians might have been dealing with the weather with temperatures barely above 10°, a brisk wind and light rain at the end of the day. Green wore big white earmuffs to try to stay warm.

"We all have a lot of layers on," Kemp said.

"We grew up playing in just a shirt, that's it, and shorts. So this is very different for us. When I have this many layers on I'm probably at least half a club less, and it got really windy out once we came out the back.

"I was uncomfortably cold when we got to 11 and 12, but was trying to do these little jumps and stuff. But we're not used to this. We'd prefer the sun to come out tomorrow."

This is the fourth time this tournament has been held after being cancelled in 2020 because of the COVID-19 pandemic.

Spain won the inaugural tournament in 2014, followed by the US in 2016 and South Korea in 2018.
