The second place was shared between Bengaluru's Khalin Joshi (66) and Panchkula's Angad Cheema (69) at eight-under- 276 at the Rs. 30 lakh event.
Rohana (71-68-70-65), lying tied seventh and three off the lead after the penultimate round, had a vision at the start of the final round that he would shoot a 65. As it turned out, his vision came true earning him his fourth title on the PGTI.
