TCHARLOTTE - World number two Rory McIlroy, back at the scene of his first PGA Tour win, fired a five-under 67 at Quail Hollow on Thursday for a seven-way share of the first-round lead in the Wells Fargo Championship in Charlotte, North Carolina. The Northern Irishman was joined atop the leaderboard by Americans Nick Watney, Ryan Moore, Robert Garrigus, Daniel Summerhays, Derek Ernst and Monday qualifier Nate Smith. Another six players were one stroke back, including former Masters champions Phil Mickelson and Zach Johnson, and former U.S. Open champion Lucas Glover, who won this event in 2011. McIlroy, still looking for his first tournament victory this year, struggled early in the season to find his top form after switching his golf ball and clubs. –Reuters
