Seeking a fourth title in eight years in Abu Dhabi, Kaymer shot a 7-under 65 in the third round on Saturday to extend his overnight lead from one stroke to six. He moved to 20-under 196 overall — a record-low total here after 54 holes.
"I feel like punching myself," said McIlroy, who only missed two fairways and one green in regulation all day. "I'm going to try to win the other tournament — he (Martin) is playing different golf than everyone else."
Belgium's Thomas Pieters shot 70 to stay in second place but his chances of a first win on the European Tour were virtually dashed by another exhibition from Kaymer on a National Course for which he has a great affinity.
The numbers Kaymer is putting up in the United Arab Emirates capital are mind-boggling. He is 107 under here in his last 31 rounds, hasn't dropped a shot in 43 holes and can break his record score of 24 under — set in 2011 — with a 67 or less on Sunday.
Kaymer's three wins in Abu Dhabi — the opening event of the year for many players — came in 2008, '10 and '11 and he also has a second and fifth place.
