Youmin Hwang fired a course-record, 10-under-par 62 on Thursday, and she holds a three-shot lead at the midway point of the Lotte Championship in Ewa Beach, Hawaii. The 22-year-old South Korean eagled the opening hole in the second round at Hoakalei Country Club. Jessica Porvasnik and first-round leader Akie Iwai of Japan are tied for second at 12 under. Australia’s Gabriela Ruffels and Japan’s Nasa Hataoka, who each produced a 69 in the second round, share fourth place at 10 under. It’s very different to Korea and (playing) in Korea LPGA.
