Jessica Korda shot a six-under 65 to go to extend her lead to three shots at the LPGA's LA Open at Wilshire Country Club on Thursday. World-number-one Jin-young Ko is in second at ten-under after matching Korda with a 65 while her South Korean compatriot Sei-young Kim is third at nine-under after shooting a 66. The third and final rounds of the LA Open will be held on Friday and Saturday to allow players time to travel to Singapore for next week's HSBC Women's World Championship.
