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.
Englandâ€™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 Scotlandâ€™s Sally Watson and Franceâ€™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. Canberraâ€™s Nikki Campbell is at four-over and tied for 20th. WAâ€™s Whitney Hillier and Queenslandâ€™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 â€˜tram linerâ€™ from 40 feet.
â€œIt was tough out there today, probably harder than yesterday. The wind was much stronger and just relentless so I was very pleased with that,â€ said Johnson, who honed her links skills growing up at windy Westward Ho! In Devon.
â€œIt feels like Iâ€™m putting well so hopefully it will continue well tomorrow. Itâ€™s more in the head than anything else.â€
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 tourâ€™s history. Dame Laura Davies was 47 when she won the Hero Honda Womenâ€™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 Englandâ€™s Holly Clyburn and amateur Richard Bevan, with Johnson and ex-footballer Alan Hansen lying in third.
