Furue, 22, recorded 10 birdies on Sunday – including a string of six in a row starting on the sixth hole – to claim a three-stroke win at Dundonald Links.

New Zealand's Lydia Ko, who began the final round with a share of the lead, had to settle for a share of fifth place, five shots back.

Furue, the reigning Japan LPGA player of the year, blew away the field to finish 21-under, on 267.

"I didn't think I would win as a rookie," Furue said. "I'm very grateful and very happy that I was able to win at a links course."

Furue sank a 40-foot putt for birdie at the par-3 15th hole to take her first lead. She added birdies on her final two holes to join Thailand's Atthaya Thitikul (JTBC Classic) as the second LPGA Tour rookie to win a tournament this year.

France's Celine Boutier (69) collected seven birdies against four bogeys to finish in second place.

South Korean Kim Hyo-joo (66) and Cheyenne Knight (67) finished in a tie for third place, while Alison Lee (66) and Ko (71) tied for fifth.

Defending champion Ryann O'Toole (65) finished in a tie for 15th place with China's Xiyu Lin (70).

Australia's Minjee Lee also tied for 15th place while Hannah Green had a share of 34th.

"I've been waiting for a round like this. Nine birdies, two bogeys. Can't complain much about the round at all," O'Toole said.

"You have to stay patient. I look at a round like Evian my second round, five-over. I didn't even play five-over. It was one of those. Didn't make any birdies.

"I knew that the game is there. So see where it takes me into next week."
