MELBOURNE, Australia (AP) -- American Stacy Lewis and Australia's Sarah Kemp shared the Women's Australian Open lead at 4-under 69 on Thursday, leaving top-ranked Yani Tseng a stroke back in her bid to win the event for the third straight year.
Lewis, the Kraft Nabisco winner last year, had six birdies and two bogeys in the LPGA Tour opener at historic Royal Melbourne, the 2011 Presidents Cup venue that is hosting a women's professional event for the first time.
Kemp had a bogey-free round.
Tseng won the tournament, sanctioned this year by the LPGA Tour for the first time, the last two seasons at Commonwealth Golf Club. The Taiwanese star went on to win 12 worldwide titles last year, including the LPGA Championship and Women's British Open.
Brittany Lincicome and Julieta Granada matched Tseng with at 70 in the event also sanctioned by Australian Ladies Professional Golf and the Ladies European Tour.
