Ravindra Jadeja and Axar Patel extended India's lead to 144 runs after Rohit Sharma scored a century as the hosts ended day two of the opening Test against Australia at 321 for seven here on Friday.

Despite wickets tumbling at regular intervals at the other end, Rohit (120 off 212 balls) batted with composure to bring up a hard-fought century, his ninth in the format.
