Left-arm orthodox spinner R. Sai Kishore's maiden match haul of 10 wickets ensured a staggering 645-run victory for South Zone over North to set up a clash with West Zone in the Duleep Trophy final starting on Wednesday.
The margin of victory was one of the highest in Indian first-class cricket.
West Zone also won their semifinal in commanding fashion beating Central Zone by a comfortable 279-run margin. The final will be played in Coimbatore from September 21, and it will be a five-day affair.
