After making good account of themselves in the fourballs format with a 69 Thursday, Robert Pactolerin and Tony Lascuna lost their teamwork in the alternate golf shots as they fumbled with that seven-over card to slide to ninth place with 148 at the Pinx Golf Club in Cheju Island, Korea.
That was 10 strokes behind the third-running Hong Kong squad, which had a 138 after a 73.
Only the top three finishers after four rounds will advance to the WMC World Cup slated in Argentina in December.
Korea continued to dominate the field at home, firing a 69 and posting a four-stroke lead over Thailand halfway through the event.
Taiwan is in fourth with a 140 after a 74 while Malaysia (76-142), India (73-143), Marianas (75-143) and Singapore (77-143) in that order.
