India 109 (Kuhnemann 5-16, Lyon 3-35) and 163 (Pujara 59, Lyon 8-64) lead Australia 197 (Khawaja 60, Jadeja 4-78, Umesh 3-12) by 75 runs
Indore: Australia are on the verge of victory inside three days in the third Test against India after Nathan Lyon claimed eight for 64 in Indore on Thursday.
Following a first-innings score of 109, India were dismissed for 163 in their second go.
Australia need just 76 to win - but have to score them on a pitch where 30 wickets have fallen within two days.
Victory for Australia would secure their place in the final of the World Test Championship in June.
India lead the four-Test series 2-0 after big wins in Delhi and Nagpur, and they know a 3-1 series win or better will guarantee their place in the World Test Championship final at The Oval.
The second day began with Australia resuming on 156-4, and after overnight batters Cameron Green and Peter Handscomb added 30 to the total, the tourists lost their last six wickets for 11 runs to fold for 197.
It left Australia with a lead of 88 and Lyon wrecked India's top order before they could erase their deficit.
He removed both openers, Shubman Gill and Rohit Sharma, before dismissing Ravindra Jadeja, while Matthew Kuhnemann claimed the prized wicket of Virat Kohli (13).
Only Cheteshwar Pujara (59) resisted to keep India in the contest, but a superb one-handed catch from stand-in captain Steve Smith at leg slip dismissed him off Lyon's bowling.
