DALY CITY, Calif. (AP) So Yeon Ryu shot a tournament-record 9-under 63 on Thursday to take the early first-round lead in the Swinging Skirts LPGA Classic.
Playing in the first group of the day off the 10th tee, the South Korean player had seven birdies in an eight-hole stretch on the back nine and added two more on the front nine at Lake Merced.
Japan's Haru Nomura was second after a 65. China's Xi Yu Lin and the Netherlands' Christel Boeljon shot 67, and two-time defending champion Lydia Ko topped the group at 68. Ko already has two victories in California this year, winning the Kia Classic and ANA Inspiration in consecutive weeks.
