A mixed second round for Stephanie Meadow at the Lotte Championship in Hawaii saw her drop out of contention for the tournament as Youmin Hwang fired a course-record, 10-under-par 62 to take a three shot lead.
Meadow started the day four shots off the lead after her opening round of 68 but was unable to match that in her second round as she hit four birdies and three bogeys to sign for a 71.
That left Meadow on five under for the tournament, as she sits in joint 21st.
Hwang, meanwhile, eagled the opening hole in the second round at Hoakalei Country Club. She added nine birdies and one bogey the rest of the way, leaving her at 15 under.
Jessica Porvasnik and first-round leader Akie Iwai of Japan are tied for second at 12 under. Porvasnik carded a 65 on Thursday, and Iwai shot a 68.
Australia's Gabriela Ruffels and Japan's Nasa Hataoka, who each produced a 69 in the second round, share fourth place at 10 under.
Speaking through a translator, Hwang said: "First of all, I broke my life-best score. At the same time, I broke the course record, so I feel very good."
Hwang has two career victories on the LPGA of Korea Tour, and she won a Taiwan LPGA Tour event this year.
