World number two Rory McIlroy has joined six other players in a leadership log jam after the first round of the Wells Fargo Championship. McIlroy birdied the 18th hole at the Quail Hollow Club in Charlotte to end the opening round alongside Americans Ryan Moore, Nick Watney, Robert Garrigus, Derek Ernst, Daniel Summerhays and Nate Smith on five under at the top of the leaderboard. Watney and Moore both posted bogey-free rounds with the former, who started on the back nine, producing a brilliant run home, birdying the first, second, third, seventh and eighth holes to take a share of the lead. Moore also took a little while to get going on Thursday but a birdie on the 9th hole set him up for an impressive back-nine performance. The 30-year-old birdied the 10th, 13th, 14th and 15th holes to card a five-under 67 in North Carolina. McIlroy looked on track to be the sole leader at the end of the first round of the PGA Tour event when he birdied four consecutive holes from the par-five 5th onwards. While the 2010 champion also birdied the 10th and 11th holes, bogeys on the 9th and 12th left the Northern Irishman on four under and he needed another birdie on the 18th to take a share of the lead. The tight nature of the opening round of the Wells Fargo Championship was underlined with 30 players within three shots of the leading seven players. Rod Pampling and Steven Bowditch are the highest-placed Australian players at three under, while John Senden is a shot further back heading into Friday&aposs second round.
