South Korea's Ilhee Lee took advantage of calm morning conditions at Royal Melbourne to shoot a 5-under 68 and take a one-stroke lead after the first round of the Women's Australian Open.
Lee had four back-nine birdies while Ariya Jutanugarn bogeyed her final hole to finish with a 69. The 19-year-old Thai earned a spot in an LPGA tournament in Thailand at the age of 11, making her the youngest player to qualify for an LPGA tournament.
New Zealander Lydia Ko, playing her second tournament as world No. 1, shot 70 and was tied for third with Canadian Alena Sharp and South Korea's Kwak Min-seo.
The Women's Australian Open is sanctioned by three tours: the LPGA, Ladies European and Australian Ladies tours.
