Madelene Sagström stays in second place and buttons in on Australian Mijee Lee at the top.
The Australian, with a total of 17 under par, is only one stroke better than Sagström after three days of play.
- I got a really good point today and if I can just continue my game, get good putts, give myself good opportunities, then you never know, Sagström says according to AP.
- But I have to focus on the present, she continues.
Sagström was briefly up in the split lead with Lee when the latter did bogey on hole eleven.
Lee repaired the mistake with an eagle on subsequent holes.
The leader quartet before Sunday's final round consists of: Minjee Lee (Australia) -17, Madelene Sagström (Sweden) -16, Lexi Thompson (USA) -14 and Angel Yin (USA) -11.
The next Swede in the starting field is Frida Kinhult in shared twelfth place and seven under par.
