Aussie pair Darren Beck and Adam Blyth have finished second and third respectively at the Hero Honda Indian Open at Delhi Golf Club.
Beck (15-under) was denied the title by Liang Wen-chong (16-under) who finished a stroke clear of the field.
Beck rattled off seven birdies in a faultless final round while Blyth could only manage an even-par 72 on the last day.
Two birdies in the final two holes saw Liang overcome the spirited final-day charge from Beck to claim the prize.
Beck looked on course to snatch victory after the rookie birdied the last to finish 15-under before Liang overturned his slender advantage.
"I'm delighted with my performance this week," Beck said.
"I'm surprised to have done well but it's because I've been focusing on my mental game in the past few weeks. I felt confident and not nervous which has been my main problem before."
Liang had led since a stunning opening round of 60 and was three-under at the turn, only for a bogey at the 14th and a double bogey at the 15th to see him trail Beck by a shot approaching the last two holes.
But having birdied the 17th, Liang produced a superb chip on the 18th to set-up a three-foot birdie putt and a winning score of 16-under-par following a two-under-par final-round of 70.
"I'm delighted with this win. It's my first triumph from start to finish and I'm really happy," said Liang.
"This is an important win for me. It proves that I'm heading in the right direction."
"I was over-thinking about my shot on the 14th hole when I was in the bunker which resulted in a bogey and I chose the wrong club on the 15th hole. I was 154 yards to the pin and I used an eight iron. But I kept it together with two birdies for a great finish."
Beck's countryman Marcus Both finished on level pegging with New Zealander Mark Brown in equal 10th on seven-under.
Unho Park completed the tournament a stroke further back in a share of 16th spot while Gavin Flint and Kiwi Stephen Scahill were tied in 21st position on five-under.
Home favourite Jeev Milkha Singh claimed fourth following a 69.
