The 24-year-old Californian rode a hot putter on the inward nine picking up five birdies in the last eight holes to card a three under 68 and finish at 13 under, which was enough o edge out defending champion Brooke Henderson (66).

When Kang bogied Olympia Fields’ challenging par-3 17th, and Henderson closed with two birdies, the pair were tied at the top of the leaderboard. But Kang hit two solid shots to get to the green in two on the par-5, and then two-putted for the win.

"I just told myself it was my week. It was my day," Kang said.

The former two-time US Women’s Amateur Champion got emotional when she opened up about the influence her family had had on her success.

"If I could wish anything, I would wish that my dad saw me won," said Kang, whose father, K.S, died from brain and lung cancer in 2013. "I think that it's been a really difficult road for me the past four or five years. Its life, though, you pick yourself up and you have to keep working hard at it, and then believe in what you're doing, and not letting yourself down.

FINAL SCORES

"I just know that he's here for it. What are the odds that my first win is a major? Pretty sure he had something to do with it. It's just incredible. But I know that he was there, because I felt — I felt him with me every day, and I still do."

Queensland’s Sarah Jane Smith was the best placed of the Australians, rounding out her tournament with an even par 71 to finish at four under and T14.
