Irish teenage prodigy Rory McIlroy was in pole position to chalk up his maiden win as a pro in the fog-hit Dubai Desert Classic on Saturday after a double eagle blast. The 19-year-old Ulsterman was one of 51 golfers unable to complete their third rounds as organizers scrambled to get back on schedule after six hours of play were lost to fog on the opening two days. After setting the pace in the first two rounds he kept his nose in front in the third round thanks to a tap-in eagle on the 10th, his last shot of the day, after he hit his second 225 yards to two feet. That left him at 15-under par, two strokes ahead of in-form Louis Oosthuizen of South Africa and Australian leftie Richard Green. Back-to-form Englishman Justin Rose was lying third at 11-under par and a further stroke back were rising German star Martin Kaymer, Paul Casey of England, Scott Strange of Australia and Thomas Levet of France. All had a handfull of holes to complete their rounds when the third round resumes early Sunday morning with the players going out in groups of three after that for the final round in order to avoid having to extend into Monday. There was disappointment though for another South African, crowd favorite and course record-holder Ernie Els. The three-time Desert Classic winner missed the cut by one stroke after a disappointing 73 had left him on level par. Watney in front In Arizona, American Phil Mickelson failed to make the cut in his season debut, shooting a 73 in the second round of the six million dollar FBR Open on Friday. Mickelson, the fourth ranked player in the world, was well back of second round leader Nick Watney, who carded a bogey-free 63. Watney is gunning for his second career title. His Friday round featured four birdies and a pair of eagles to move to nine-under 133 overall. The second round was suspended due to darkness with the final group out on the course with two holes to play. Mickelson never found his rhythm en route to 73, which left him at seven-over 149 and well off the projected cut of even. It marks the first time in his 18-year career that Mickelson has missed a cut in his season opener.
