South Australian Stephanie Na shares fifth position heading into the final round of the Aberdeen Asset Management Ladies Scottish Open presented by EventScotland.

Na has posted rounds of 72 and 73 on Fidra Course at the Archerfield Links in East Lothian to be at one-over-par for the tournament.

England’s Trish Johnson fired an impressive second round of two-under-par 70 in breezy conditions to open up a commanding lead going into the final round. At eight-under-par, the 48-year-old from Wiltshire is six strokes clear of Scotland’s Sally Watson and France’s Gwladys Nocera, with another Frenchwoman Anne-Lise Caudal a stroke further behind on one-under-par.

It has been a good week for the Australians with all, but one, making the cut. Rebecca Artis is tied for 10th at two-over-par, while Nikki Garrett is a further shot back and tied for 16th. Canberra’s Nikki Campbell is at four-over and tied for 20th. WA’s Whitney Hillier and Queensland’s Bree Arthur share 30th position at six-over-par. Unfortunately Alison Whitaker missed the cut which was made at 10-over.

Johnson began with five pars on the Fidra Course at Archerfield Links in East Lothian and made her first birdie of the day on 15, before dropping a shot on 16. She picked up two more strokes on the front nine, on six and seven, where she holed a ‘tram liner’ from 40 feet.

“It was tough out there today, probably harder than yesterday. The wind was much stronger and just relentless so I was very pleased with that,” said Johnson, who honed her links skills growing up at windy Westward Ho! In Devon.

“It feels like I’m putting well so hopefully it will continue well tomorrow. It’s more in the head than anything else.”

With 18 Ladies European Tour titles and three LPGA trophies in 28 years on tour, Johnson is already a Life Member of the LET, but if she wins on Sunday, she will become the oldest winner in the tour’s history. Dame Laura Davies was 47 when she won the Hero Honda Women’s Indian Open in November 2010.

In the Pro-Am team competition, Campbell and her amateur partner Gavin Corbett continued to lead on 14-under-par, followed by England’s Holly Clyburn and amateur Richard Bevan, with Johnson and ex-footballer Alan Hansen lying in third.
