- South African leads Chun In-gee and Hinako Shibuno

Just when a glimmer of hope had been provided to the field, Ashleigh Buhai slammed the door shut in the style of a champion.
Buhai’s third shot to Muirfield’s par-five 17th had sailed long of the green. She had a dicey chip remaining. Not content to trickle her ball towards the hole and save par, the South African holed out for a birdie four. Her lead had been extended to six shots.
