India regained much of the ground by claiming four wickets in the final session as Australia failed to capitalise on a century partnership for the opening wicket in the third and penultimate cricket Test at Mohali on Friday.
At stumps on the second day, Australia were 273 for seven with comeback man, Steven Smith and Mitchell Starc, batting on 58 and 20 respectively.
While Ravindra Jadeja proved to be the surprise package for India with three wickets, including two in two deliveries, it was Ishant Sharma's late burst that pushed Australia on the backfoot after Ed Cowan and David Warner were back on track with a 139-run partnership for the first wicket after Michael Clarke opted to bat.
His flagging career on the line after a string of failures, Cowan silenced the doubting Thomases with a dogged knock of 86, which consumed 238 balls. Cowan found the fence eight times, but will be disappointed at not being able to convert his efforts into a century, despite getting three lives.
His partner, Warner made a fluent 71 off 147 balls with help of nine fours.
The duo's efforts, though, were a bit undone with the loss of seven wickets in the final two sessions of play.
Ishant had Brad Haddin and Moises Henriques bowled to reduce Australia to 244 for six late into the final session of play at the Punjab Cricket Association Stadium, where the first day was washed out due to a heavy downpour.
Jadeja returned and immediately had Peter Siddle trapped in front of the wicket.
Making a comeback after more than two years in the wilderness, Smith stood firm and showed the right mix of aggression and resolve against the Indian spinners.
After Cowan departed, caught by Virat Kohli off Ravichandran Ashwin at first slip, it was left to Smith to ensure that Australia carry on the fight in this must-win game.
Smith, the 23-year-old from New South Wales, did his job admirably, adding crucial runs with Brad Haddin for the fifth wicket, which frustrated the Indians for a while before Sharma opened the floodgates.
In the second session, Jadeja got the wickets of Warner and Clarke for nought while Pragyan Ojha accounted for Phillip Hughes, as Australia reached 180 for three at tea.
The Cowan-Warner stand, incidentally, is also Australia's best partnership for the opening wicket on this ground, eclipsing the 87-run stand set by Shane Watson and Simon Katich back in 2010.
After having Warner caught by Mahendra Singh Dhoni, who ran forward after the ball looped off the batsman's bat-pad, Jadeja bagged the most important wicket of skipper Clarke, who was stumped by Dhoni off the first ball the batsman faced. The ball turned away sharply on landing, and an over-confident Clarke made the mistake by stepping out straightaway.
Twelve overs later, Ojha had Hughes caught down the leg-side by Dhoni, ending the out-of-form batsman's yet another miserable stay at the crease. Hughes, in the series, has scored no more than a mere two runs off 70 balls against the spinners while getting out five times.
India could have added one more to the wickets tally, but Virat Kohli at first slip dropped an edge that Ojha induced off Cowan.
Warner struck nine fours while facing 147 balls. What was also important was that the opener spent 206 minutes in the middle after a run of poor scores. It turned out to be good session for Jadeja, who delivered after the specialist bowlers failed to give the hosts a breakthrough.
That India struggled prior to that was only due to Warner and Ed Cowan, who produced Australia's best opening partnership of the series as the visitors went to lunch at an impressive 109 for no loss.
Warner led Australia's promising start with a flurry of boundaries, including a few delectable drives through the off-side.
There was a chance for Ojha to dismiss Warner right after he completed his fifty, but Kohli, positioned at first slip, could not get to the ball.
Opting to bat after Clarke won the toss for the third time in the series, Australia were served well by the two openers, even as the Indian bowlers looked for wickets on a surface that is likely to assist the spinners over the next few days.
It was a departure from the norm as far as the wicket was concerned the PCA is known for assisting the quicker bowlers.
Seeking to make a fightback after two reverses in the first two Tests in Chennai and Hyderabad respectively, wickets off successive deliveries put the brakes on the Aussies.
After a four-over first spell, Ishant, playing his 50thTest, was replaced by Ashwin in the ninth over, and the off-spinner straightway extracted turn and bounce.
Bringing Ishant back, instead of Ojha, for another six-over spell, however, seemed a bit surprising.
When Ojha was finally introduced in the 25thover, in place of Ishant, the left-arm spinner was greeted with two boundaries one through the covers off a short ball and the next one nudged down the leg-side.
Ojha did manage to induce an edge off Cowan, but it flew past Kohli at first slip.
With his four specialist bowlers used within the 30th over, Jadeja was introduced in place of Ashwin. It was surprising to see Jadeja given a more attacking field than the two specialist spinners -- with a leg-slip in place alongside the first slip and the short-leg fielder -- but the all-rounder lived upto his skipper's expectation.
India made two changes to the squad, bringing in Ojha and in place of Harbhajan Singh and handing Shikhar Dhawan his Test cap for the dropped Virender Sehwag. Australia have brought in Brad Haddin, Mitchell Starc, Steven Smith and Nathan Lyon in place of the injured Matthew Wade and suspended James Pattinson, Shane Watson and Glenn Maxwell.
