Defending champions Mumbai pulled off a thrilling six-run win over a fighting Karnataka to clinch the coveted Ranji Trophy title for the 39th time in Mysore today. Mumbai's win looked unlikely when Manish Pandey and Ganesh Satish were at the crease as Karnataka chased a mammoth 338-run target. The duo, who had come together when Karnataka were in dire straits at 46 for three, batted with gusto, assurance and caution to take the fight into the enemy camp, raising 209 runs for the fourth wicket. As long as Pandey, who made a magnificent 144 in trying circumstances, was at the square Karnataka were in the reckoning of winning their seventh Ranji title.But once he departed, caught at slip by Mumbai skipper Wasim Jaffer off left-arm spinner Iqbal Abdulla minutes before lunch, Mumbai slowly but assuredly started taking control of the game. Satish, who laboured hard for 318 minutes, made 75 before being adjudged leg before wicket to Dhawal Kulkarni. Stuart Binny (17), Sunil Joshi (16) and R Vinay Kumar (15) batted with resolve to take Karnataka closer to the target. But quick strikes by Kulkarni and Ajit Agarkar (5 for 81) ensured that Mumbai emerged triumphant in the end.
