American Jennifer Song, 28, shot an opening 7-under 65 to take a 2-stroke lead at the Women’s World Championship in Singapore.
She reeled off seven birdies at the Sentosa Golf Club in a round that was interrupted for two hours by lightning.
Michelle Wie and Ji Eun-Hee (both 67) were tied for second while another nine players finished a further stroke back at 4 under.
Top-ranked Shanshan Feng (70) bogeyed the last hole, while No. 2 Lexi Thompson (75) struggled in making five bogeys.
Still chasing her first LPGA win eight years after turning professional, Song took the outright lead when she made five birdies in an eight-hole stretch.
“At times it has been a great struggle because I know I can win out here, but I just never have been given that chance yet,” Song said. “But I kept believing that someday it will happen.”
Nine players were knotted at 68: Brooke Henderson, Ariya Jutanugarn, Danielle Kang, Chun In Gee, Jessica Korda, Madelene Sagstrom, Chella Choi, Su Oh and Park Sung Hyun.
Kang managed to post a bogey-free round despite a freak accident that broke her tooth before she teed off.
“I was stretching out on the floor and next thing I know, I slept 30 minutes,” Kang said. “I broke a tooth. Call the dentist on range. It’s all good.”
Louis de Jager’s strong finish gave him a 1-shot lead after the first round of the Tshwane Open in Pretoria, South Africa.
De Jager birdied three of his last four holes for a 7-under 64 to move just ahead of fellow South African Thomas Aiken, American Julian Suri and Chilean Felipe Aguilar.
De Jager hasn’t won a European Tour event but his best result came at this event in 2013, when he tied for third.
Starting on No. 9, de Jager had two good runs at Pretoria Country Club. He finished his opening nine with three straight birdies before picking up another three as he came home.
Aiken, a three-time winner on the tour, reeled off five birdies in five holes after starting with a bogey. He had eight birdies in all in his 6-under 65.
