Kiwi golfer Lydia Ko has stayed in the top five after another impressive round at the LPGA Tour event in Thailand.
Ko carded a five-under 67 to move up one spot into a share of fourth at 11-under, and stay within touching distance of the leaders.
Thailand's Patty Tavatanakit leads her home event at 16-under, three shots ahead of compatriot Atthaya Thitikul, who in turn is a shot clear of Germany's Caroline Masson.
Tavatanakit, who held off Ko's famous final-round charge to win the ANA Inspiration major earlier this year, led by one stroke going into the final hole, but produced a superb eagle on the par-five 18th to complete a flawless day which had previously consisted of six birdies.
Ko, who is tied with Gaby Lopez, had an eventual round, with eight birdies, a bogey and a double bogey. That double bogey came on the fifth hole, after Ko had started her round with three birdies in four holes, but a drive into the rough saw her unable to find her ball, and having to take a penalty.
