New Zealand amateur Lydia Ko has become the youngest winner of a professional golf tour event, at the age of 14.

Ko came close to winning the same tournament last year, aged 13, missing a putt on the last green to lose by one shot.

This year, she held her nerve to record a three-under-par final round of 69 and beat Becky Morgan of Wales in the 54-hole tournament.

England's Laura Davies closed with a 71 to finish 14 shots off the pace.

"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 plans to play in about 30 tournaments this year, including professional events over the next two weeks - the Australian Masters at Royal Pines on the Gold Coast and the LPGA's Australian Open at Royal Melbourne.

She added: "I'll play in mostly amateur tournaments after that, and my schedule looks pretty busy for several months."
