Mumbai off-spinner Ramesh Powar bagged seven wickets for 140 to guide West Zone to a 274-run win over South Zone on the final day of the Duleep Trophy final match at the MA Chidambaram Stadium in Chennai today. West dismissed South for 403, thanks in large measure to Powar, who showed there’s no substitute for accuracy and persistence on a dusting track. S. Badrinath (59) and Dinesh Karthik (75) added 121 in 149 balls for the fourth-wicket, briefly raising hope that South might draw the match. But Badrinath found the fielder on the boundary, Karthik disturbed the stumps with his pad in trying to leave a Powar off-break, and although R. Ashwin chipped in with an unbeaten 46, there was little else from the others. Brief scores: West Zone (1st innings): 459 South Zone (1st innings): 199 West Zone (2nd innings): 417 South Zone (2nd innings): 403
