Minjee Lee is in a commanding position at the Women's PGA Championship.
The Australian golf star holds a four-shot advantage heading into the fourth and final day of the Frisco tournament.
She entered the third round three shots off the lead, but shot three-under par to move to -6 overall.
Contenders struggled in the Texas heat as the 29-year-old enjoyed the only bogey-free round of the day.

"I just tried to stay patient out there. You can’t get ahead of yourself, especially in these conditions," Lee said.
"It’s only getting harder and harder, I think, with the pressure of a major championship and the course demands so much from you.
"I tried to stay within myself and play the shot as best I could – just stay patient and take it as it comes."
Lee, the sister of PGA star Min Woo Lee, already has two golf majors to her name.
She took out the Evian Championship in 2021 before snaring the US Women's Open in 2022.
Victory at the PGA Championship would see her take home US$2.4 million (approx. AU$3.7 million) in prize money.
Fellow countrywoman Grace Kim is tied for 10th place at +3 after shooting an impressive four-under on Saturday.
Elsewhere, Australians Steph Kyriacou and Karis Davidson are tied at 43rd, Gabriela Ruffels is tied at 50th, Hannah Green is tied for 69th, and Hira Naveed is outright 78th.
