Spinners Pragyan Ojha and R Ashwin plotted a dramatic West Indies batting collapse as India very nearly pulled off a sensational win before the visitors pegged them back to a nerve-wracking last-ball draw in the third and final cricket Test here today. After the hosts conceded a 108-run first innings lead, Ojha (6/47) and Ashwin (4/34) ripped through the batting order to bundle out West Indies for a paltry 134 in the second innings, leaving the hosts a target of 243 off 64 overs on a tricky fifth-day track.
