Karrie Webb will take a one-stroke lead into the final round of the HSBC Women's Champions at Singapore's Sentosa Golf Club thanks to three key birdies on the back nine.
The 2011 champion, who has led every round this week, shot a 70 to move to 11-under overall, but the pressure will be on when she goes up against 2012 winner Angela Stanford in the lead group on Sunday.
The American matched Webb birdie-for-birdie over the final five holes to shoot a 69 and remains just behind the veteran Australian along with half dozen other players on a tight looking leaderboard.
"Even when I was not giving myself a lot of good birdie opportunities early on, I had to tell myself it's Saturday, there's plenty of golf left to be played and just to be patient," said Webb. "And fortunately I listened to myself for a change."
Spain's Azahara Munoz fired an eagle and four birdies for a 5-under 67 to surge into a third-place tie with Taiwan's Teresa Lu at 8-under.
America's Paula Creamer, who briefly held the lead with Webb and Munoz, holed six birdies to go with three bogeys to finish in fifth place at 7-under.
Stanford joked afterward there was only one way she could get the advantage over seven-time major winner Webb on Sunday.
"I'm going to send Webbie a six-pack (of beer) tonight," she said.
Webb replied, without missing a beat, "I'll probably drink wine coolers."
Defending champion Stacy Lewis' disappointing week, meanwhile, looks likely to end her streak of 13 consecutive top 10 finishes on the LPGA Tour. Lewis shot a 73 on Saturday, leaving her far down the leaderboard in joint-42nd place.
Lewis, the reigning Women's British Open champion, is only three away from matching Webb's LPGA record of 16 consecutive top 10 finishes, set in 1998-99.
