Rory McIlroy managed only eight holes on Thursday before play at the Barclays Singapore Open was called off in mid-afternoon because of a thunderstorm.
The world number one had just bogeyed the short eighth to return to level par, five behind leader Thomas Bjorn, when the day's action came to a premature end.
It means the Northern Irishman faces the prospect of 28 holes on Friday, although it is nothing new for the event - last year it was cut to three rounds and the play-off continued into Monday.
Former Ryder Cup star Bjorn, the 41-year-old Dane, carded a 66 to lead by a stroke from England's Simon Khan, Spaniard Pablo Martin and Thai golfer Chinnarat Phadungsil, with back-to-form Paul Casey among those only two back.
McIlroy, a controversial absentee from last week's world championship in China, started with a bogey, but then had birdies on the fourth and fifth while being watched by girlfriend Caroline Wozniacki.
Brief though his day's work was, it took the 23-year-old Northern Irishman closer to securing the European Tour money list title as playing partner Louis Oosthuizen, needing a win to keep alive his hopes, ran up a double-bogey seven on the 587-yard seventh and stood two over par.
That put the South African alongside American Phil Mickelson, in with a morning 73, while three-time winner Adam Scott had to be content with a level-par 71 and Ireland's Padraig Harrington could do no better than 74 in the hot and humid conditions.
That included a drive into the lake en route to a seven at the long fourth, a closing bogey - and not a single birdie all day.
Bjorn, three times a winner last year, birdied three of his last six holes and said: "I thought the course would be extremely difficult and my iron play was not 100 per cent, but I hit enough good ones and never got into big trouble.
"Any time you can find some shadow you do it. You don't do too much practice and you pace yourself - it's a long, long week and you've got to stay energised."
