Two bogeys in the last three holes saw Rory McIlroy fall back to a tie for the lead with Alvaro Quiros on seven under after the the second round of the Hong Kong Open.
Panupol Pittayarat is at six under par after the Thai returned a 65 containing an eagle and three birdies while Scot Richie Ramsay is also only a shot off the lead after shooting a 66.
Miguel Angel Jimenez, who carded an even-par 70, is a further shot back alongside Danny Lee and Pariya Junhasavasdikul.
Starting the day level at the top of the leaderboard alongside Quiros and David Horsey on six-under, McIlroy picked up his first birdie of the day at the third but immediately relinquished the shot at the next.
However, further birdies at the eighth, 10th and 12th saw the 22-year-old move to nine under par before he ran into trouble on the 16th when his drive ended up behind a tree and he was forced to pitch out onto the fairway for an eventual bogey.
A wayward tee shot at the 17th landed in the rough down the left but he recovered for par before another poor tee shot at the last found the trees and he was forced to lay-up before pushing his putt right of the hole to finish with a 69 and level with Quiros.
The Spaniard had earlier also shot a 69 that featured four birdies and three bogeys including a disappointing five at the ninth, his final hole, while Horsey carded a 72 to drop back to four-under.
Ian Poulter is one under par after the defending champion produced a 68 containing an eagle, three birdies and three bogeys while a 71 saw Padraig Harrington finish one-over as his hopes of sneaking into the Dubai World Championship receded.
Colin Montogmerie also looks set to be around at the weekend after a 69 should see the Scot make the cut at two over par.
Justin Rose is likely to miss out, however, the Englishman following up Thursday's 74 with a 69 that left him three-over for the tournament.
