World number four Inbee Park has retained her lead after the third round of the Mission Hills World Ladies Championship with a three-under 69. With Norway&aposs Suzann Pettersen and Soo Jin Yang of South Korea pushing up the leaderboard into second and third, Park produced four birdies on the back nine to hold onto a two-stroke lead heading into the final round at the Sandbelt Trails Course at Mission Hills Haikou. Park looked in danger of giving up her lead by the end of Saturday&aposs play when she bogeyed the first and fifth holes in China. But a birdie on the par-four seventh got the 24-year-old South Korean back on track and she birdied the 11th, 12th, 14th and 16th holes to finish the third round on 14-under overall. World number eight Pettersen sits second on 12-under, while Yang is two shots further back in third. Pettersen produced three consecutive birdies to end the front nine and then completed her bogey-free 67 with birdies on the 12th and 16th holes. Yang carded five birdies of her own but a bogey on the 15th saw her finish with a four-under 68. Spain&aposs Carlota Ciganda, who started the third round in second overall, dropped to fourth on eight-under with a two-over 72. Ariya Jutanugarn of Thailand is a shot behind Ciganda, tied for fifth with Italy&aposs Veronica Zorzi and South Korean pair Hyo-Joo Kim and Bo-Mi Suh. Bree Arthur and Karen Lunn are the two highest-placed Australians at the Mission Hills World Ladies Championship on three-under overall, while Kristie Smith is two-under.
