Scot Lawrie on course to equal Tour record

(CNN) -- Scotland's Paul Lawrie has a chance this weekend to achieve something which has even eluded Tiger Woods so far.

Only two players -- David J Russell in 1992 and Jesper Parnevik three years later -- have ever gone through a European Tour event without dropping a stroke.

Woods failed to join them on the very last hole of the 2002 American Express world championship at Mount Juliet in Ireland, but Lawrie is halfway there after adding a 69 to his opening 67 in the Johnnie Walker Championship at Gleneagles.

The 40-year-old former British Open champion, fighting for his Tour career a decade on from his Carnoustie triumph, stands eight-under-par and now leads by two strokes from Northern Ireland rookie Jonathan Caldwell, Dutchman Maarten Lafeber and Argentine Daniel Vancsik.

Jose Maria Olazabal birdied the 18th for a 68, that included birdies on five of his first six holes. The veteran Spaniard shares third place on five-under 139 with Danish Ryder Cup player Soren Hansen (70), Gregory Bourdy of France (68) and Shiv Kapur of India (70).

"I wasn't in trouble a lot, but when I had to I obviously kept the round going, which you have to do when you have no bogeys," Lawrie told reporters -- after doubling his first day advantage.

"I've been prone to the odd hook in my career and I've certainly got rid of that the last couple of days. I missed a few putts, but I'm very pleased with the way I hit it again. Overall you're not going to grumble, but I'm a golfer and you always grumble!"
