GOLD COAST, Australia (AP) -- South Korean-born Australian teenager Su Oh shot a 4-under 69 Sunday to win the Australian Ladies Masters by three strokes in only her second start as a professional.
Oh, the co-leader after the first round, finished with a 7-under total of 285 on the Royal Pines resort course, making birdies on her final four holes.
Katherine Kirk of Australia and Florentyna Parker each shot 69s while Parker's English countrywoman Charley Hull, one of the overnight leaders, had a closing 73. They all finished tied for second.
The 18-year-old Oh finished second at the Victorian Open last week in her professional debut.
Defending champion Cheyenne Woods, Tiger Woods' niece, shot 71 to finish tied for 26th, 10 strokes behind Oh.
