June 24 (UPI) -- Hannah Green became only the third female Australian golfer to win a major with her victory at the Women's PGA Championship at Hazeltine National in Chaska, Minn.
Green, 22, was one stroke better than defending champion Park Sung-hyun on Sunday. Green carded nine-under to join Jan Stephenson and Karrie Webb as Australians to win a major tournament.
"I'm pretty much speechless," Green said. "I was really nervous the last five holes."
Green won $577,500 for finishing in first place. She carded 72 in Sunday's final round and clinched the victory with a five-foot par putt.
Playing in only her seventh career major, Green entered Sunday with a one-stroke lead over Ariya Jutanugarn. Jutanugarn shot five-over Sunday and finished tied for 10th at three-under.
Melissa Reid and Nelly Korda shot six-under and tied for third place. Danielle Kang and Lizette Salas tied for fifth by shooting five-under.
"[I just wanted] anything to just be winning in majors the first event," Green said.
