KUALA LUMPUR - So Yeon Ryu birdied five of her first seven holes en route to a six-under-par 65 and a two-stroke lead at the half-way point in the Sime Darby LPGA Malaysia tournament Friday. The South Korean added two more birdies on the back nine before suffering the only blemish on her card, a bogey on the par-four 14th hole, leaving her at 11-under for the event. Hot on her heels were a hard-charging trio tied at 9-under, led by Japan’s Ayako Uehara, who orchestrated a bogey-free 63. England’s Jodi Ewart Shadoff and 17-year-old phenomenon Lydia Ko of New Zealand stayed level with Uehara after both shot 64. South Korea’s Eun-Hee Ji joined them 9-under, while three golfers — Shanshan Feng of China, Azahara Munoz of Spain, and Thailand’s Pornanong Phatlum — were a further stroke back.–AFP
