The 29-year-old South Korean seized control with four successive birdies from the 9th hole at The Renaissance Club in North Berwick, the same course that hosted the men's Scottish Open last month.

West Australian Minjee Lee finished tied sixth on 11 under after posting a final-round 67, while compatriot Su Oh was joint 13th with a 275 total.

Hur capped off the performance in style with further birdies at the 16th and 18th holes for a five-under-par 66 on a day when club workers were kept busy squeegeeing the greens to keep the course playable in relentless rain.

“Honestly I don't like links courses but after this week I love it!" Hur told Sky Sports.

"It was really tough today with the rain but my caddie Gary is from Scotland and he helped me a lot on the course and he worked really well this week."

Overnight leader Moriya Jutanugarn (71) and US Women's Open champion Jeongeun Lee6 (70) tied for second place on 16-under.
