The first round was completed Friday morning after another fog delay. Friday's fog delay of over one hour, pushed tee times back even further after a two- plus-hour fog delay on Thursday. The second round, which was suspended due to darkness, will resume Friday evening at 10:15 PM (ET), with the third round beginning no earlier than 2:00 AM.
Mark O'Meara, playing with McGinley, posted an 8-under 64 to move into second place. He stands at 10-under-par 134.
Brian Davis (66) and Greg Owen (65) share third place at 8-under-par 136. They are joined there by first-round leader Bradley Dredge, who is eight-under through nine holes.
Tiger Woods, who shared second place here in 2001, shot a 4-under 69 in the second round. He stands three shots further back at minus-5.
McGinley, who finished his first round on Friday, was on fire all day. He closed his first round with four straight birdies at Emirates Golf Club and had five birdies over his last six holes.
The Irishman quickly picked up where he left off to start his second round. McGinley burst out of the gate with four consecutive birdies from the 10th, his opening hole, to grab a share of the lead at minus-8.
His streak was ended with a bogey at No. 15. He bounced right back with a 25- foot birdie putt at the very next hole to regain a share of the lead. McGinley took over first place with a birdie on No. 18, his ninth.
He again stumbled back into a tie for the lead when he bogeyed the first. O'Meara tied McGinley and three others atop the leaderboard when he birdied No. 2, his 11th.
McGinley and O'Meara both birdied the third to move one ahead of the field. McGinley dropped a pitching-wedge within five feet of the cup at the fifth to collect another birdie. That moved him to 10-under and one clear of O'Meara, who bogeyed the fourth and birdied the fifth.
McGinley drained a 25-footer for birdie on his 15th to move two ahead of O'Meara. McGinley two-putted for par on each of the final three holes to remain atop the leaderboard.
'The ball rolled for me, there's no question about that,' said McGinley. 'When you get one or two birdies you feed off it. We certainly fed off each other, there's no doubt about that.'
O'Meara kept pace with his playing partner, McGinley, most of the day. He drained a 35-footer for birdie at the fifth to return to minus-9. O'Meara capped a stellar round when he sank a birdie try from over 25 feet out at the ninth to get within one of McGinley's lead.
Woods completed his first round with back-to-back birdies from the 17th to close a round of 2-under 70. He opened his second round with a birdie on the 10th and the 27-year-old came back with a birdie at the 13th and 17th to move to minus-5.
Woods picked up another birdie at the third, but closed with a three-putt bogey on No. 9 to end in a tie for 11th at 5-under-par 139. He is joined there by Colin Montgomerie, who also shot a 69. Peter Lawrie and Lee Westwood are also at 5-under through 15 and 11 holes, respectively.
'I didn't play particularly well, but I ended up with a decent number to keep myself in the tournament,' Woods said. 'I basically just grinded around the golf course today. I didn't really do anything great.'
Paul Casey shot a four-under 68 and Simon Dyson posted a 69 to move to 7- under-par 137. They are joined in a tie for sixth by David Howell, who is 7-under through 12 holes.
Gary Murphy (67) is one stroke further back, as is Marcus Fraser, who is 6-under through nine holes.
Robert-Jan Derksen, the defending champion, will likely miss the cut as he finished at 3-over-par 147. The cut line is expected to be even-par.
