He birdied six of the nine holes for 30 and a total of 67 to finish 25th, his second best finish of the season.

Amandeep Johl shot a fourth straight 70 to be eight-under 280 and tied 37th. Anirban Lahiri, a teammate of Bhullar, when India won the silver medal in 2006 Asian Games shot a final round 67 to tie for 47th at five-under 283.

Bhullar also thanked his psychologist Pradeep Aggarwal for the win.

'It was a great week. I have been very happy with my ball striking and my recent work with Pradeep, who has been with me for last few months, has paid off,' he said.

The win in Jakarta comes on the heels of three top-10 finishes earlier in the season on Asian Tour and three titles on Indian PGTI Tour.

'The difference has come because of my approach. I am very positive in my approach,' said Bhullar, whose father, Harbhajan Singh is a former athlete.

Bhullar started the final round one shot ahead of Blyth. He immediately struck rhythm as he birdied second, third and fourth holes to go 20-under. A fourth birdie on sixth meant he had pulled clear at 21-under.

Over the next 12 holes, he played most maturely and added one more birdie on par-5 13th and then calmly parred the remaining five holes.

Bhullar, who shot 23 birdies during the week had just one bogey and that came on the first day on the ninth, which was his closing hole for the first round. He played his last 27 holes without a bogey.

The Jakarta win ensures him a two-year exemption and more importantly greater confidence to set higher goals.
