Fifteen-year-old Lydia Ko maintained her impressive form with a 10-under-par score of 63 in her opening round at the Australian Women's Open.
The New Zealander, who won her home Open at the weekend, underlined her reputation as the brightest prospect in golf at the Royal Canberra Golf Club.
Playing with world number one Yani Tseng and Michelle Wie, her round included 11 birdies and an eagle.
"We had a few good conversations so that made it more enjoyable," she said.
Korea-born Ko opened with one of three bogeys and added: "After a few birdies, I settled in and I felt pretty comfortable.
"I was pretty nervous when I saw the draw that I was playing with two of the big names."
In January 2012, Ko became the youngest player, male or female, to win a professional event with her victory at the New South Wales Open and was the youngest winner on the LPGA Tour when she was victorious at the Canadian Open.
