Nathan Lyon has spun Australia back into contention on day two of the fourth and final Test against India.
Despite some poor fielding, the visitors are still in a position of strength heading into the third day, with India still trailing by 52 runs with just four wickets in hands.
India was set at 2/153 at tea, with Cheteshwar Puajra (53*) looking set for another big score.
Enter Lyon. He removed the half-centurion in the first over after the break. This opened the flood gates for Australia's number one off-spinner, moments later he sent Nair back to the pavilion.
A 49-run partnership between Ajinkya Rahane, and Ravi Ashwin, looked to have steadied the ship for the Indians. However, another double strike meant that they were both watching in the rooms by the time the new ball was taken at the start of the 87th over.
Things could have been a lot better for Australia, but youngster Matt Renshaw dropped two catches at first slip, including one in the first over of the new ball. Both of the errors came off the bowling of Pat Cummins, who proved his worth, bowling a good mixture of line and length and fiery short pitched deliveries.
Overnight India sit at 6/248, still trailing the Aussies' first innings score of 300. The match is primed for a thrilling finish, with runs in the second half of the Test likely to be crucial.
Australia will begin day three looking to clean up the Indian tail. If the side does take a lead into the second innings, it will likely be small. However, every run could be crucial down the stretch.
Any lead above 300 will be difficult for the hosts to chase in the fourth innings of the Test match. Thus, the game will likely be in the hands of the Australian batsmen. If they struggle to post a decent total, it will be an uphill battle for the bowling attack.
But if they could can post a similar score to that of the first innings, they can bat their opposition out of the match, leaving India with only the possibility of a draw.
It's shaping up to be the Test match we were all hoping for. A tough contest between bat and ball that should come down to the final two days. Australia is aiming to win its first Test series in India since 2004/05.
