Rahil Gangjee leapfrogged to tied 12th with a late assault for the best finish by an Indian, while fellow SSP Chowrasia joined 2005 champion Shiv Kapur at 19th place at the end of the Volvo Masters of Asia in Bangkok on Sunday.
Riding on his impressive front nine, Gangjee signed off with a round of three-under 69 to aggregate five-under 283.
Local hero Prayad Marksaeng birdied the 18th hole at the Thai Country Club for three-under 69 to win the $ 750,000 Asian Tour finale by a shot from overnight leader Juvic Pagunsan and England's Chris Rodgers, who both bogeyed the closing hole for a 75 and 68 respectively.
Marksaeng produced several Houdini-like escapes on the back nine to total 13-under 275 and pocket $ 135,000.
Gangjee began well with birdies on the second and fourth holes followed by an eagle on the par-five seventh. A bogey on the ninth snapped the rhythm and though he dropped two more shots in the 11th and 16th as well, Gangjee atoned with birdies on the 13th and 17th.
Menawhile, Shiv Kapur was left to rue his disappointing final round of two-over 74, which denied him a better finish.
Overnight tied 13th, Kapur needed another solid round to finish inside the top 10 but came up with his worst card of the week. When he began, there were no signs of impending trouble as Kapur birdied the first and fourth holes before dropping his first shot on the ninth.
But, the Delhi golfer was in all sorts of trouble on the trecherous back nine, as he bogeyed the 11th, 13th and 15th holes to slip down the leaderboard with a total of three-under 285.
Chowrasia too was denied a grand sign-off and a birdie quartet was cancelled out by as many bogeys as the Kolkata pro settled for a level-par round.
