Pat Cummins struck thrice on a tense third day of the third Test to give Australia hope of a victory over India that would ensure the visitors retain the Border-Gavaskar trophy.
The four-Test series is level after two dramatic matches and the contest in Ranchi is on track to be a classic. India were 360-6 at stumps on Saturday, trailing Australia by 91 runs.
Cummins and Josh Hazlewood bent their backs throughout an absorbing day in which wickets and runs were hard to come by. Virat Kohli was out cheaply again, while Cheteshwar Pujara became the top-ranked Test side's first centurion of the series.
Pujara was 130 not out at stumps. Steve Smith will feel aggrieved the talented batsman wasn't dismissed on 22 when a contentious referral was turned down by third umpire Nigel Llong.
Smith reviewed a confident lbw shout from Steve O'Keefe. Front-on replays appeared to show the ball hit bat before pad, but the Snickometer picked up a clear noise that suggested it might have glanced the pad first.
