England's Bronte Law and Mel Reid are through to the last 16 of the Bank of Hope LPGA Matchplay in Las Vegas.

After halving with Amy Olson and beating Austin Ernst 2&1 earlier in the week, Law won 6&5 against Annie Park on Friday to move into the knockout stage.

She will next play American world number six Danielle Kang - the only player to go 3-0 in the group stage.

Reid will face Australian Minjee Lee after winning a sudden-death play-off against Spain's Azahara Munoz.

After a two-up defeat by Munoz and wins over Gerina Piller and Hannah Green in the round-robin, Reid beat her two-time European Solheim Cup team-mate on the first hole of the play-off to advance.

"I didn't want to play many more holes," she said. "I was a bit tired, so I tried to get it done as quickly as possible."

It was one of six sudden-death play-offs on Friday, with Anna Nordqvist eliminating top seed Jin Young Ko of South Korea on the first play-off hole after earlier beating her 5&3.

Thailand's two-time major winner Ariya Jutanugarn eliminated Sarah Schmelzel with a par on the first play-off hole, moving into the knockout phase despite losing twice in the group stage.

American Brittany Altomare knocked out South Korean world number three Kim Sim-young with a par on the second play-off hole.

Sophia Popov, who won the Women's Open in 2020, completes a quartet of Europeans in the knockout stages after a 6&5 victory against Park Sung-hyun of South Korea.
