At the end of round four, the top 35 players earned their cards for the 2016 PGTI season.

Aman missed an up and down from the bunker for his second bogey of the day on the 17th. Nonetheless, the three-time winner on the amateur circuit last year, cruised to victory having posted the day's best score of 72.
The Patna lad is now all set to turn professional in April after representing India at the 2016 Bonallack Trophy.
Aman said, "I've had a good week in Ahmedabad. But I know that I need to work harder and get better if I have to make an impression on the professional stage. I got the momentum going with the two birdies on the ninth and 11th today.
Raju Singh finished runner-up after a final round of 75.
Delhi's Wasim Khan was third at 12-over 200 while Bengaluru's Syed Saqib Ahmed finished a further shot back in fourth place.
