Atwal had a chance to come from one shot behind Fritelli to win win regulation but his eagle putt lipped and the birdie put him in a play-off.
Then in the play-off he reached the edge in two, but left his chip shot to about 10 feet and the putt stopped at the lip and Fritteli, also two on, two-putted for birdie at the Euro 1million (approximately USD 1.07 million) event sanctioned by the Asian Tour, Sunshine Tour and European Tour. This was his second win of the season.
As for the other two Indians, Shiv Kapur (70) was T-16th and SSP Chawrasia (70) was T-27th.
Atwal got his best finish in three years since the 2014 win in Dubai Open on Asian Tour. His best since and only top- 10 since then has been T-7 in Taiwan this year.

Atwal said, "I didn't read the line in my second shot (play-off), didn't hit a good shot and didn't hit a great putt. Dylan obviously did the right thing and deserves to win. I'm happy with the way I played this week but right now I'm just disappointed to lose the tournament."
