Hannah Jun of the United States shot a six under par 66 to lead by three strokes after the opening round of the Aberdeen Ladies Scottish Open presented by EventScotland.
The 25-year-old from San Diego carded six birdies on the Fidra course at Archerfield Links near Gullane in East Lothian to finish ahead of England’s Rebecca Hudson and South African Ashleigh Simon.
Scotland’s Catriona Matthew was one of four players a stroke back on 70 alongside Italian Diana Luna, England’s Henrietta Zuel and Caroline Afonso of France
Meanwhile Matthew cannot be ruled out sitting just four shots from the lead with two rounds to play.
“I’m quite happy. It’s always good to finish well,” said the 2009 Ricoh Women’s British Open champion from nearby North Berwick.
“I birdied three of the last five. I made a hash of the last: was in perfect position for two, a bad chip and raced the putt past so it was a good five from six feet.”
The next best placed Scot was Clare Queen on one under, alongside England’s Sophie Walker, Italian Veronica Zorzi and Germany’s Caroline Masson, the third round leader at Carnoustie last month.
