Rory McIlroy is in with a great chance of emulating his feat of five years ago in the Wells Fargo Championship at Quail Hollow.
McIlroy's 2010 triumph at the Charlotte, North Carolina course was his first success on the PGA Tour and he has since gone on to win four Majors as well as securing his current status as world number one.
The Ulsterman fired a second round five under par 67 to move to seven under after his opening round of 70.
"It's a good score and I am right there for the weekend," said McIlroy.
"It's a case of more of the same now. I feel good out there, mentally I feel very sharp.
"I am not putting myself under stress in terms of having to save pars.
"If I can just be a bit more crisp with my approach play - hopefully that will be the case.
"If you can put your ball in play and put it well up the fairway you are going to have a chance.
"I've found a good groove with the driver. I drove it beautifully last week at Sawgrass and I've continued that.
"My iron play wasn't maybe as sharp as it should have been."
The 26-year-old is just one off the clubhouse pace set by Americans Martin Flores and Patrick Rodgers in the $7.1million event.
McIlroy plays in the BMW PGA Championship at Wentworth next week before hosting the Dubai Duty Free Irish Open at Royal County Down.
An impressive four under par round of 68 helped Michael Hoey shoot up the leaderboard at the Spanish Open.
The Belfast golfer hit six birdies and two bogeys in his second round at El Prat to move to within two shots of aptly named leader Edouard Espana of France who is seven under.
Defending champion Miguel Angel Jimenez failed to make the most of a record-equalling hole-in-one.
Jimenez hit his ninth European Tour ace - equalling the record of Colin Montgomerie - on the eighth, but came home in 39 to card a 71 and finish one under, six off the pace.
Jimenez is bound for the Irish Open which starts on Thursday week.
