World No. 1 Lydia Ko and South Korean star Amy Yang are engaged in a brilliant duel for the title on the back nine after play resumed in the ISPS Handa Women's Australian Open.
Yang, born in Korea but schooled on the Gold Coast, resumed from an hour's delay because of lightning in the area by taking a birdie at the par-five 10th hole to grab the lead from Ko at eight-under par.
Yang had been left to ponder her four-metre putt for eagle over the delay in play, but she almost made the putt. It horse-shoed around the hole and stayed out.
Then Ko chipped up close and birdied the same hole a few minutes later to join Yang at eight-under.
Thailand's Ariya Jutanugarn is the closest of the remaining players at five-under.
Australia's Katherine Kirk is at one-under through 11 holes and compatriot Minjee Lee is even par through 15 holes of the final round.
