Veterans Karrie Webb and Angela Stanford continue to set the pace going into an intriguing final day of the HSBC Women's Champions tournament at the Sentosa Golf Club.
Webb, 39, fired a two-under 70 (205 total) to maintain a one-shot lead over 36-year-old American Stanford (69), who won the 2012 edition.
"The main thing is to be ahead of everyone, that's where I want to be for one more day, which I'm hopeful of if I keep playing the way I am," said the Australian, who won the US$1.4 million (S$1.77 million) event in 2011.
Spain's Azahara Munoz (67) heads a chasing pack of seven players who are within four strokes of each other, setting up a potentially explosive Sunday at the Serapong course.
World No. 1 Park In Bee (71) has work to do in joint-10th, and could lose her top ranking if she finishes lower than joint-third and Suzann Pettersen (currently six shots off the top in seventh) wins the tournament.
Singapore teenager Amanda Tan, 14, posted her best round of 75 (235 total) and is three shots off second-last spot.
