Rain affected play each day of the tournament and Aphibarnrat, the leader after the second round was completed Saturday, played just two third-round holes before play was again stopped.
A large storm Saturday afternoon led organizers to suspend play for the day and reduce the tournament, scheduled for 72 holes, to 54 holes.
Aphibarnrat had a birdie and a bogey in his only third-round holes and is at 11-under par for the tournament. He's one stroke up on Charl Schwartzel, who also birdied the first hole in the third round.
There's a crowd of seven players, including Padraig Harrington, lurking at 9-under. Andres Hansen pulled into contention by going 4-under through eight holes of the third round. Harrington had completed four third-round holes at 2-under.
Earlier Saturday, world No. 3-ranked Luke Donald finished his second round at 2-over 73 and missed the cut for the first time in a regular European Tour event.
