Playing on the Brickyard Crossing course on the grounds of the famous motor speedway, Hur all but lapped the competition, leading wire-to-wire.

She was never headed after starting the final round with a two-shot lead, closing the deal emphatically with a bogey-free four-under-par 68, while Dane Nanna Koerstz Madsen shot 67 to claim second place.

Hur finished on 21-under 267, continuing the dominance of South Koreans on the LPGA Tour this year.

Korean players have captured 13 of 26 tournaments this year, headed by World No.1 Jin Young Ko, who has won four times.

Hur, Sung Hyun Park and Sei Young Kim have won twice each, while Jeongeun Lee6, Amy Yang and Eun-Hee Ji have single victories.

"I'm just trying to enjoy my golf for a whole year," said Hur in a greenside interview as she rubbed champagne from her eyes after being doused by her peers.

"Wire-to-wire, I really wanted to do it and I did it, so I'm happy."

Hur, 29, also won the Ladies Scottish Open last month.

Sarah Kemp and Su Oh were the best of the Australians, both sharing 15th place.
