McIlroy, Karlsson share early lead in Abu Dhabi Jan 26 05:36 AM US/Eastern ABU DHABI, United Arab Emirates (AP) - Rory McIlroy shot a 5-under 67 in the opening round Thursday at the Abu Dhabi Golf Championship for a share of the early clubhouse lead, three strokes in front of playing partner Tiger Woods. McIlroy, the U.S. Open champion who has had three top-five finishes at this tournament, made three birdies in his first four holes but bogeyed two of the next four. He steadied with three birdies on his back nine, including a chip-in on No. 8 from just off the green. Robert Karlsson of Sweden also had a 67. The pair were a shot ahead of Gareth Maybin of Northern Ireland. Woods holed two birdies in a bogey-free 70, but struggled on the greens, missing several putts. Top-ranked Luke Donald shot a 71.
