Fourteen-year-old New Zealand amateur Lydia Ko has become the youngest winner of a professional golf tour event, taking the women's New South Wales Open by four strokes Sunday.

Ko, the world's top amateur, broke Japanese star Ryo Ishikawa's mark of 15 years, 8 months, and Australian Amy Yang's women's record of 16 years, 192 days in the Australian Ladies Masters.

The South Korean-born New Zealander shot a 3-under 69 to finish at 14 under for the tournament, four strokes clear of Becky Morgan of Wales. Ko came close to winning the tournament last year, but missing a putt on the last hole to lose by a stroke.

Britain's Laura Davies closed with a 71 and a 54-hole total of 216, 14 strokes behind.

"To be part of history is like a miracle," Ko said. "It's not something you can have by clicking your fingers."

"My driver and iron play were probably the nicest to me over the past two days," Ko added. "I also putted well, but I was in good position on most of the greens because I was able to make approaches from good places on the fairways."

Ko, a Grade 11 student at North Harbour near Auckland, plans to play about 30 tournaments this year, including professional events over the next two weeks at the Australian Masters at Royal Pines on the Gold Coast and the LPGA's Australian Open at Royal Melbourne.

"I'll play in mostly amateur tournaments after that, and my schedule looks pretty busy for the next several months," Ko said.

Ko, who says her role models are American golfers Michelle Wie and Alexis Thompson, moved to Australia with her family from Seoul in 2003.

"My sister (Sura) was attending school in Canada, and we were going to move there, but when I started playing golf regularly, we decided New Zealand would be the best place to come because of the weather," she said.
