Michael Hoey is in second place, five shots off leader Ross Fisher after the third round of the Tshwane Open in South Africa.
Hoey had carded seven birdies in a row during his second round of 65, one off the European Tour record, but was unable to repeat such heroics on Saturday.
The five-time European Tour winner carded six birdies and three bogeys in his 69 and will partner Fisher in the final group on Sunday. After a fine round of 67, Fisher said he had found his range after a bogey on his opening hole.
"I didn't get off to the best of starts on the first but then found my range on the second and third and that really got me settled in," Fisher said.
"I hit it very close on six and seven after dropping one on five, so that was a nice bounce back and it felt like I played a lot better on the back nine. I missed a couple of make-able ones but I am not going to be sat here too unhappy with 67 in those conditions.”
England’s Simon Dyson and Spain’s Carlos de Moral are in joint third, a shot behind Hoey, after third rounds of 71.
Of the other Irish, Waterford’s Kevin Phelan is three strokes behind Hoey after a third-round 68. Shane Lowry’s third round of 70 left him on seven under par overall.
