Buhai sank eight birdies in her brilliant seven-under 64 on Saturday, putting her at 14-under for the championship.

Chun In-gee of South Korea, who had been the overnight leader, is in a tie for second with Hinako Shibuno of Japan on nine-under, while Inbee Park and Madelene Sagstrom are two shots further back at seven-under.
