Defending champion Nelly Korda ran her streak of bogey-free play to 38 holes as she took a three-stroke lead at the Swinging Skirts in New Taipei City, Taiwan on Saturday.
Korda shot a 7-under 65 to move to 18 under overall heading into Sunday's final round.
"I don't remember the last time I (went 36-plus holes without a bogey)," said Korda. "I don't think I've ever actually done that. But I'm just playing really solid golf, and there's still so much golf to be played."
Australia's Minjee Lee is alone in second after shooting her third consecutive round of 5-under 67. Germany's Caroline Masson, who shot 6-under 66, is another stroke back in third place.
Korda will be paired with Lee and Masson on Sunday.
"With the two girls I'm going to be playing with tomorrow, Minjee and Caroline, they are going to for sure shoot some low scores," said Korda.
"So it's going to take a low one to stay consistent to win tomorrow, so hopefully I can get that finish. But it would be great to win again here in Taiwan. Still have 18 holes, so I'm not going to get ahead of myself."
The 21-year-old Korda, who won her first title here in 2018, is shooting for her second title of the season and third of her career.
Lee, who was runner-up to Korda here last year, doesn't mind her position heading into the final round.
"I think it's just a little bit easier to be in the mind-set of chasing than trying to like lead," said Lee. "So yeah, I mean, I've been in both positions before, so it's nothing new to me. I'll just take it as it comes."
South Korea's Mi Jung Hur, the second-round leader, struggled to a 1-under 71 as she fell five shots off the lead. Hur has won twice in five tries when holding the lead at the midway point but faces an uphill battle Sunday as she targets her third title of the year.
The total purse for the event is $2.2 million, the winner taking home $330,000.
