Ha Na Jang took a one-shot lead at the Sime Darby LPGA Malaysia behind a second-round 65, but she better not look back.
Chasing Jang in the top 10 are the likes of Inbee Park (8 under, T-3), Yani Tseng (8 under T-3), Alison Lee (8 under, T-3), Minjee Lee (7 under T-6), Shanshan Feng (7 under, T-6), Lydia Ko (6 under, T-10) and Jessica Korda (6 under, T-10).
They could apply some pressure to Jang, a rookie on the LPGA Tour who has finished runner up three times this season but has yet to get a win.
