Sourav Ganguly notched up his 16th Test century while stand-in skipper Mahendra Singh Dhoni missed the mark by a whisker before their bowling colleagues landed late blows on Australia to put India in the box seat on day two of the second cricket Test at Mohali today. Finishing the day at 102 for four wickets is hardly what Australia captain Ricky Ponting would have fancied and Michael Hussey (37) would have a crucial role to play tomorrow if the visitors are to avoid follow on and wipe out the arrears. Sourav Ganguly (102) struck his 16th century in his 111th Test -- which has already seen him cross the 7000-mark -- and Mahendra Singh Dhoni (92) fell just eight runs shy of his ton as India`s first innings ended with 469 runs on board.
