Lahiri has all but put the champagne in the ice bucket as he took a big step towards wrapping up the Order of Merit crown with his Tied-21st place and a cheque of USD 78,400 in CIMB Classic.
With his closest rivals Hend and Andrew Dodt, both from Australia, finishing below him at the Kuala Lumpur Golf and Country Club, the 28-year-old Lahiri extended his lead over second-ranked Hend to USD 647,453.
Only three Indians Jyoti Randhawa (2002), Arjun Atwal (2003) and Jeev Milkha Singh (2006 and 2008) have won the Asian Tour Order of Merit earlier.

"When the time comes, if that does happen, it will be a very special moment for me," added Lahiri, who has amassed USD 1.13 million on the Asian Tour this season.
The 42-year-old Hend said he needed a top-two finish in Malaysia to keep the Merit battle alive but settled for a share of 27th position after closing with a 67. Dodt finished tied 56th to remain third on the Merit list.
