An unrelenting Rory McIlroy secured his second Dubai Desert Classic victory in six years with a 2-under-par 70 in the final round to win by three shots on Sunday in Dubai, United Arab Emirates.

The Northern Irishman's 22-under 266 total matched the lowest in the history of the tournament, set by Stephen Gallacher in 2013 and Thomas Bjorn in 2001.

The top-ranked McIlroy, whose victory at this event in 2009 was his first as a professional, made only three birdies Sunday, but he kept mistakes off his card. His only bogey of the round came on the par-3 seventh hole at Emirates Golf Club's Majlis course.

"I just wanted to keep my ball in play and not really make any mistakes and try and pick off some birdies when I could on the par-5s," McIlroy said.

"I did what I needed to do. It wasn't the best round that I've played this year, but I got the job done and that's the most important thing."

Sweden's Alexander Noren, making a comeback from a wrist injury that restricted him to playing two events in 2014, had eight birdies in his round of 65 and took second place at 19-under 269.

"I never even thought of winning, Rory's playing so good," said Noren, who started the year ranked 654th.

Defending champion Gallacher closed with a 69 and finished third at 16-under 272.

There was a five-way tie for fourth, involving Germany's Martin Kaymer (64), France's Gary Stal (68), Austria's Bernd Wiesberger (70), England's Andy Sullivan (70) and Denmark's Morten Orum Madsen (73).

The $2.5 million tournament forms the closing leg of the three-stop Desert Swing of the European Tour.

Also the 2011 winner, the 40-year-old Goggin finished at 11-under 269 at Panama Golf Club. He earned $112,500 for his fifth victory on the tour and first since 2011.
