Stacy Lewis takes a two-shot lead into the final round of the Omega Dubai Ladies Open at The Emirates Golf Club on Saturday.
The American, who led by one going into the third day, posted three birdies and a bogey on her way to a two-under-par 70.
Thailand's Pornanong Phatlum, who trailed the Solheim Cup star by three overnight, signed for a 69 to claim sole possession of second place, three shots clear of Scotland's Vikki Laing and Diana Luna of Italy, who both matched Phatlum's score, and Spaniard Carlota Ciganda (73).
Sweden's Pernilla Lindberg, one behind Lewis at the start of the day, posted a 75 to drop back into a share of fifth spot alongside compatriot Louis Larsson (68), with veteran Laura Davies (71) a further stroke adrift.
England's Charley Hull (73) was forced to settle for a share of 11th place after a double bogey at nine, and a dropped shot at 12, cancelled out birdies at two of her opening five holes.
Meanwhile, South African Connie Chen ensured she would be leaving the Emirates with the keys to a gleaming new Mercedes E400 after sinking her six-iron tee-shot at the 160-yard 15th hole.
