India close in on win after Jadeja's allround brilliance
- Jadeja hits fifty, claims three wickets
- Australia 137 all out in second innings
- India need 87 runs to seal 2-1 series win
Steve O'Keefe sent back Kumar in the next over and Cummins (3-94) got rid of Saha, who made 31, with another short delivery.
Off-spinner Nathan Lyon (5-92) dismissed debutant Kuldeep Yadav for seven to wrap up the India innings and complete his second five-wicket haul of the series.
Australia's top order let them down when they walked out to bat.
Karun Nair spilled David Warner at slip off Bhuvneshwar Kumar for the second time in the match but the opener, who has managed just one fifty in the series, was unable to capitalise and was caught behind for six off Umesh.
Much depended on skipper Steve Smith and the highest scorer of the series hit three delectable boundaries before guiding a Bhuvneshwar Kumar delivery onto his stumps to depart for 17.
Umesh (3-29) then had Matt Renshaw caught behind as Australia lost three wickets before they had wiped out India's first innings lead.
Jadeja dismissed Shaun Marsh, Pat Cummins and Steve O'Keefe before Ashwin joined the party, claiming 3-29.
Glenn Maxwell topscored with a fluent 45 before paying the price for offering his pad, and no shot, to Ashwin.
