Thailand’s Atthaya Thitikul held a slight advantage over historic champion Nelly Korda when the third round of the LPGA Chevron Championship was halted due to storms in Texas.
Atthaya, the overnight co-leader, is at 11 under after 12 holes of his round.
World number one Korda holed a four-foot putt at the 12th when play in the first major of the year resumes on Sunday.
The 25-year-old is aiming to tie the LPGA record of five wins in five consecutive starts.
Success would see her join Nancy Lopez (1978) and Annika Sorenstam (2005) as the only players to achieve this feat.
Korda shares second place with Canadian Brooke Henderson who had seven birdies and an eagle in her first 14 holes before dropping a shot at the 16th.
Overnight co-leader Im Jin Hee of South Korea is nine under through 11 holes.
Jodi Ewart Shadoff leads the British contingent on five under, while English amateur Lottie Woad, who won the Augusta National Women’s Amateur earlier this month, is a little further back alongside Scotland’s Gemma Dryburgh.
Atthaya is playing her first tournament of the year after recovering from a thumb injury, but the 21-year-old says she doesn’t mind the challenge of an extended day on Sunday.
“I think it’s not that bad,” she said. “I think last year in Malaysia I played more than that in one day with the play-offs, 27 holes, which is good. Still young now, still good.”
