The tournament has been trying to catch up since a two-hour weather delay on Thursday. More storms Friday delayed things further and the start of play Saturday morning was delayed over three hours before the second round could be completed.
At the conclusion of the second round, the cut was made at 3-under-par 137 with 79 players advancing.
The third round is scheduled to resume at 7:30 a.m. local time on Sunday. The players will remain in the same groups for the final round, which is scheduled to start at 8:50 a.m.
Frankie Minoza was on fire during his third round racking up seven birdies, an eagle and one bogey. He was minus-8 through 15 holes and stands in a tie for second place overall at 14-under par. He was joined there Carlsberg Malaysian Open winner Thongchai Jaidee (11 holes), Mardan Mamat (nine) and Nicolas Colsaerts (nine).
Wiratchant was steady once his third round got going. He parred his first four holes before draining a birdie try at the fifth. The Thailand native then parred his final four holes at Cengkareng Golf Club before the round was suspended for the night.
'The weather delays are not good at all,' Wiratchant said. 'I got to the club at 10:00 a.m., but sat around waiting for nearly six hours before I could tee off the third round. Now, I'll have to prepare myself for a 27-hole session Sunday, but it's good to still be leading.'
Minoza was the story of the third round though. He started his round with one birdie in his first four holes before catching fire.
The Filipino dropped in a birdie putt at the par-4 fifth and came right back with another birdie on the par-5 sixth. Minoza wasn't done as he birdied the seventh to get to minus-10.
Minoza then birdied the eighth. He continued to rise up the leaderboard with a chip-in eagle at the par-5 ninth. Around the turn, Minoza kept going with birdies on 10 and 11 to join Wiratchant in the lead. However, Minoza tripped to a bogey at the 13th before played was stopped for the day.
Jaidee was also hot during his third round. After posting just one birdie over his first five holes, the Thailand native birdied five of his next six holes to climb into a share of second place.
Colsaerts parred his first eight holes before a birdie at the ninth gave him a share of second.
Mamat carded a birdie at the first. He ran off three consecutive birdies from the fourth to move to 14 under. He parred his final three holes before play was halted for the night.
Eiji Mizoguchi, Andrew Buckle and Adam Fraser share sixth place at 12-under par with six, six and nine holes respectively left to play.
Colin Montgomerie, who needs to win this event to get into The Masters in two weeks, was 2-under through 14 holes of his third round. He stands nine shots off the pace at minus-6.
