Rahil Gangjee and three of his compatriots fell by the wayside, while veteran Gaurav Ghei just managed to finish inside the cut line as the Indian contingent put up a mundane show in the second round of the Bangkok Airways Open in Koh Samui on Friday.
Arjun Singh carded a three-under 68 to be the highest placed Indian at tied 17th after the halfway stage in the USD 300,000 Asian Tour event.
At the top, Antonio Lascuna (132) returned his second successive card of five-under 66 to grab the lead, with Chang Tse-Peng (67) and Marc Pucay (64) breathing down his neck from one shot behind.
Arjun Singh began well and finished almost in the same manner, picking up six shots, before dropping three shots in the middle stretch to settle with a two-day total of four-under 138 which placed him tied 17th.
Himmat Rai (141) brought home a card of 70 to move up to tied 38th, but Gaurav Ghei survived some torrid moments before managing to hang around for weekend action.
After his disastrous opening round of 75, the veteran managed a two-under 69 card that saw him finish with 144, just enough to stay on for the last two rounds.
Joining him at tied 63rd were the Amandeep Johl (73) and Anirban Lahiri (75) duo.
Rahil Gangjee (149) was not as much lucky and the Kolkata pro crashed out with a horrendous 79, while Gaganjeet Bhullar (150, Firoz Ali (153) and Digvijay Singh (153) also bade adieu.
