"I don't know what golf course Inbee Park is playing," Green said.

Park added to her legend by cruising to a three-shot triumph at Royal Adelaide on Sunday to capture her 20th LPGA title.

The seven-time major winner tamed wicked winds which made a mess of most others, including Green.

The Australian finished tied 13th at six-under-par - eight shots adrift of Park, who claimed her first LPGA title since March 2018.

"I didn't know when my 20th win was going to come and everybody was like 'are you stuck?'," Park said.

"And finally I get to reach the 20th in Australia. It's a special place to reach that position."

Perth's Green stumbled with three early bogeys, cruelling her quest to bridge the gap on Park, whose winning margin was the same as the three-shot cushion she slept on as overnight leader.

"Today was frustrating," Green said.

"I felt like I hit some good shots but just not the right club choices so I got myself in a bit of a pickle early.

"It was tough but I scrambled well on the back nine."

Former world No.1 Park carded one-over-par in the blustery conditions and was never seriously challenged.

"The wind was blowing really hard ... I just told myself if I could keep it to pars, it would be enough," she said.

The reigning Olympic champion finished clear of American Amy Olson (11 under) with France's Perrine Delacour (10 under) third.

The seemingly nerveless Park started Sunday's final round wary of her nearest challenger, 19-year-old compatriot Ayean Cho.

But Cho's hopes of catching her esteemed countrywoman were rapidly dashed. A birdie at the second hole was followed by three bogeys in the next four holes.

Veteran Olson tried to put some pressure on Park, firing a superb three-under round in often treacherous winds.

"It was a battle out there," Olson said.

Only one golfer shot a lower round than Olson on Sunday - American Cristie Kerr carded a four-under 69 - like Cho, she finished eight under and tied for sixth.

Australia's Green headed the locals, with world No.8 Minjee Lee finishing four under and 21-year-old Robyn Choi three under.
