Gautam Gambhir started the new season in right earnest with a patient century as Delhi made a pedestrian Assam attack toil by reaching 269-4 at stumps on the second day of the Ranji Trophy group 'A' encounter here on Saturday. Courtesy Gambhir's 40th first-class hundred (136 batting, 245 balls) and his 207-run third-wicket stand with another centurion Nitish Rana (110), Delhi are in the driver's seat with an aim to log home full points. This was after Assam were all out for 258, starting the day at 224 for 7 with skipper Ishant Sharma returning figures of five for 38 in 20 overs.
