In the Rs 1.2 crore prize money tournament, the Ahmedabad team received the winners cheque of Rs 36 lakh, while runners-up Bangalore pocketed Rs 24 lakhs. Krish Colombo, who finished at third place, went home richer by Rs 18 lakhs.
The Navratna team had earlier clinched the title when they defeated the same opponents, Bangalore, 3-0 on their home turf in the first edition of the IPL-style tournament.
However, Dharma still managed to complete the round with a score of one-under-69 to lose the tie narrowly.
Perera, thus, completed a hat-trick of titles in three weeks having won the Eagleburg Open in Bangalore and Standard Chartered Open in Colombo.
