Mahendra Singh Dhoni reached another landmark as he scored his 100th international half-century in the ongoing first ODI against Australia in Chennai. Dhoni scored his 66th one-day fifty to help India post 2817 against the Aussies at the MA Chidambaram stadium. The 36-year-old is only the fourth Indian player after Sachin Tendulkar (164), Rahul Dravid (146) and Sourav Ganguly (107) to score a century of fifties on international cricket. Meanwhile, India beat Australia by 26 runs.
