Shanshan Feng shot a 5-under 67 Friday to take a big five-stroke lead into the final round of the Dubai Ladies Masters.
The sixth-ranked Feng finished her third round at Emirates Golf Club with three straight birdies, giving her a tournament-record 198 total after three days.
Dewi Claire Schreefel shot a course-record 63 for second place at 203. She had nine birdies Friday, including four on her final four holes.
Gwladys Nocera (68) is in third at 204, with Cindy Lacrosse (69) and Caroline Masson (69) another shot back.
Defending champion Lexi Thompson (72) had two birdies and two bogeys to drop into a tie for 12th.
"It was frustrating. I didn't hit the ball bad, just didn't make anything," the American teenager said. "A few misreads with the putter, but it's been like that all week."
Michelle Wie (70) is 15 shots off the pace and remains tied for 35th. Carlota Ciganda, who leads the Order of Merit ahead of Masson, shot a 73.
