Grégory Havret overcame a second consecutive double bogey at the 15th to maintain his narrow advantage at the Johnnie Walker Championship at Gleneagles.
The Frenchman shot a 69 to move to 11 under par at Gleneagles, enough to give him a one shot advantage over Anthony Wall.
By the time Havret started his round he had been caught at the top of the leaderboard but jumped into a two-stroke lead with an eagle on the 516 yard second.
He then parred the next six holes before a four on the par five ninth took him to three under for the day.
A birdie-bogey-birdie run through the 12th, 13th and 14th strengthened Havret’s position but then he took six shots on the par four 15th for the second day running.
An instant reply at 16 saw him pull a stroke back and when he registered a four on the par five 18th Havret ensured he would be the man to catch on the final day.
Havret said: "It's going to be a big hunt tomorrow, especially with those Ryder Cup guys. I heard the weather will be bad, but we'll see. It's going to be quite open, for sure.
