Defending champion Na-yeon Choi maintained her two-shot lead after the third round of the Sime Darby LPGA Malaysia.
The South Korean world number four carded a three-under 68, weathering a four-hour rain delay to take her score to 13-under in the tournament.
"I don't really like being in the lead as there is more pressure," said Choi. "I prefer to play catch up and make my move in the last round. I was feeling the pressure a bit as it has been a long day, what with the four-hour delay and all. All day long it has been raining. It's tiring."
Pressure or none, Choi, who won her first Major at the US Women's Open earlier this year, registered just one bogey, on the 10th, after she birdied the first hole and added further birdies at the fifth, 12th and 16th.
It was her compatriot Inbee Park who registered the day's best score, however, posting a 65 to move two shots back. Also two shots back was Australia's Karrie Webb after her 68.
Ai Miyazato, from Japan, and Norwegian Suzann Pettersen are tied fourth on eight under.
