Bronte Law, Anna Nordqvist and Jennifer Song each carded a 6-under 65 on Thursday and share the day-one lead at the Pure Silk Championship.
Law signed for a bogey-free round, which included four birdies and a chip-in eagle on the par-5 third hole.
“Started finding myself with a good score. Nothing more to it,” said Law.
“On days like this when it’s windy just got to keep grinding all day, take the chances when they come.”
Song also signed for a clean card, highlighted by birdies on each of the three par 5s.
“It was a bogey-free round, so I was extremely happy about that,” said Song.
“Course conditions are great. Greens are firm and pretty much everything was going well. I was driving it well and I was getting it on the green.
“When I had a chance for birdie, I think I pretty much made all of them.”
Nordqvist overcame a bogey on No. 3 with seven birdies, including four straight gains on Nos. 13-16.
“I feel like I’ve played a lot of good – well, can’t say good golf – but I feel like I play a lot solid golf,” Nordqvist said.
“Just haven’t really got anything out of it. Today was very consistent, solid, and didn’t make any big mistakes.”
Brooke Henderson headlined a logjam of five players tied for fifth-place at 5-under par.
“I don’t know if the wind was supposed to stay like this the rest of the week, but it makes the course a lot tougher,” Henderson said.
Katherine Perry, Jacqui Concolino, Gemma Dryburgh and Jasmine Suwannapura were the others in the T5 group.
Angel Yin was a shot further back after a first-round 67, one clear of Brittany Lincicome (68) who is appearing in her final event of the season as she prepares for the birth of her daughter in September.
Defending champion Ariya Jutanugarn and world No. 1 Jin Young Ko each carded a 71.
