Not even a birdie-eagle finish from Rory McIlroy could put Martin Kaymer off his stride as he closed in on a third Abu Dhabi Championship in four years.
McIlroy shot a joint best-of-the-day 65, but the defending champion then birdied the same two holes and so goes into the closing round five clear on 18 under par.
Kaymer, last season's European Tour-leading money winner and poised now to replace Tiger Woods as world number two, carded a 66.
The 26-year-old has had only one bogey in his last 79 holes on the course, a simply staggering statistic that goes back to the 11th hole of his third round last year.
And McIlroy is not expecting the German to come off the rails all of a sudden.
"Martin is a very good leader," he said. "He does not lose many tournaments from the position he is in.
"If I give myself enough opportunities, as I did today, I am sure there's a low score out there and hopefully I will go close. But Martin is playing very, very well.
"I could have holed a few more, but it's swings and roundabouts and I will take 65 any day."
Kaymer, who was also runner-up two years ago, is now 74 under par for his last 15 rounds at the venue. He needs only a top-seven finish to move ahead of Woods in the rankings.
England's David Lynn (67) is in third place on 12 under, with Swede Alex Noren and South African Charl Schwartzel two further back in fourth.
