Sixteen-year-old Australian amateur Oh Su-hyun and 17-year-old Thai golfer Ariya Jutanugarn shared the second-round lead Saturday at the Australian Ladies Masters.
Oh shot an eight-under-par 64 on the soggy Royal Pines course hit by more than 16 inches of rain in the past week, while Ariya had a 65. They had two-round totals of 10-under 134 and a one-stroke lead heading into the final round Sunday of the European Ladies Tour's opening event of the season.
Australian Stacey Keating, who shot 67, and last year's Australian Open winner American Jessica Korda (68) were tied for third.
Seven-time Australian Masters champion Karrie Webb (66) and South Korea's Chella Choi (67) were tied for fifth, another stroke back.
