Northern Ireland's Rory McIlroy endured a stuttering start to his third round at the FedEx St Jude Classic in Memphis today.
The US Open champion started the day one shot clear, but carded five bogeys over his first 13 holes to slip to five under overall.
McIlroy looked in sparkling form over the first two days at TPC Southwind with opening rounds of 68 and 65.
But he dropped shots at the second, fifth, ninth, 10th and 13th holes today, with only three birdies to offset the damage.
Australia's Nick O'Hern led the way on six under alongside American trio Kevin Kisner, Kevin Stadler and JB Holmes.
After a level-par outward nine, O'Hern burst up the leaderboard with a run of three straight birdies from the 14th. He was three under for the round with one to play, with Kisner one under for the day through 15 and Stadler and Holmes level par with four to play.
