South Korean's 64 puts her five ahead after second round at Hoylake
South Korea's Jiyai Shin made the most of the calmer conditions at Hoylake to take command at the halfway stage of the Ricoh Women's British Open.
The second round was restarted on Saturday morning after 60mph gusts made the Royal Liverpool course unplayable on Friday.
Shin enjoyed the perfect start when play resumed as she chipped in for an eagle on her first hole, the 10th.
The 24-year-old former world number one, who won this event at Sunningdale in 2008, then birdied the next three holes and turned in a superb six-under-par 31.
She added further birdies at the fourth and seventh to finish with an eight-under 64, a course record which took her to nine-under 135 and five shots clear of the field.
Fellow South Korean Inbee Park (68) leads the chasing pack on four under with Japan's Mika Miyazato (70) and Karrie Webb of Australia (70) one further back.
The final 36 holes are scheduled to be played on Sunday but Laura Davies will not be around after withdrawing with an ankle injury, while Karen Stupples, Melissa Reid, Carly Booth and Charley Hull were among the home hopes to miss the cut.
Shin, who could now complete the first ever Asian clean sweep of the women's majors, said: "I think it's the best round I've ever played. My goal was one under every single day, so eight under - wow. I can't believe it."
