DALY CITY, Calif. (AP) Haru Nomura shot a 2-under 70 on Friday at Lake Merced to take the second-round lead in the Swinging Skirts LPGA Classic.
The 23-year-old Japanese player had a 9-under 135 total for a three-stroke lead over South Koreans So Yeon Ryu and Na Yeon Choi and Australia's Minjee Lee.
Nomura won the Australian Women's Open in February, pulling away to beating top-ranked Lydia Ko by three strokes for her first LPGA Tour title.
Ryu, the first-round leader after a tournament-record 63, bogeyed four of her first five holes in rain and wind and shot a 75. Lee, coming off a victory last week in Hawaii, had a 65. Choi shot 70.
Two-time defending champion Ko was four strokes back at 5 under after a 71. She birdied three of the first three holes, but bogeyed two of the last four.
