Harrington’s travails continued when he bogeyed the 11th hole to fall back to eight under and nine shots off the pace.
It was left to Holland’s Maarten Lafeber to make the biggest move up the leaderboard, the 26-year-old from Eindhoven moving to 11 under alongside France’s Olivier Edmond.
Lafeber, who led after the first r in Malaysia last week, carded a first round 64 and picked up five birdies and one bogey in his first 12 holes to move into a tie for third.
Earlier, Harrington looked intent on catching Minoza at the top of the leaderboard when he picked up shots at the third and fourth holes to move to 10 under.
But the Irishman, who had shot 28 on the front nine yesterday, could not repeat those heroics and dropped a shot on the sixth to fall back to nine under, eight shots off the pace.
England’s Anthony Wall, joint second overnight, was now 10 shots adrift after only managing a level par outward nine of 35 with two birdies cancelled out by two bogeys.
The course remained vulnerable to low scoring however, unheralded Mexican Pablo Del Olmo threatening something special when he was six under for six holes with four birdies and an eagle, three pars then halting his charge somewhat.
Seve Ballesteros was in need of something similar as he battled to make the cut, the 43-year-old Spaniard running up a double bogey six at the third and at two over for the tournament looking like missing yet another halfway cut.
