Australia has enjoyed its best day of the Border-Gavaskar Trophy series, but the drama-packed second Test against India remains in the balance after a rollercoaster three sessions.
The tourists have a lead of 62 after going to stumps at 1-61, losing Usman Khawja (6) when forced to bat for a tricky 13 overs under lights at Arun Jaitely Stadium in Delhi.
The loss of Khawaja is a blow but Australia went about quickly extending its one-run first-innings advantage in attacking fashion to shock India's bowlers.
The recalled Travis Head (39 not out off 40 balls) opened with Khawaja, filling in for veteran David Warner, who was subbed out of the match before play on Saturday with concussion.
Warner was replaced in the XI by Matt Renshaw, who is expected to bat at number five.
Head was controversially dropped for the opening Test defeat in Nagpur based on his poor record in Asia but looked at home batting at the top of the order, playing aggressively like he does in Australian conditions.
Head will resume batting with star number three Marnus Labuschange on Sunday as Australia attempt to further press its advantage in trying to level the series at 1-1.
But the undisputed star of the day for Australia was Nathan Lyon, who delivered one of the finest performances of his 117-Test career to finish with 5-67.
Lyon looked out-of-sorts during the first Test in Nagpur, going for 1-126 and was overshadowed by 22-year-old debutant spinner Todd Murphy.
But the 36-year-old could not have responded any better in the Indian capital, bowling with accuracy on a bouncy, turning wicket.
After taking 4-13 during a masterful spell in the morning session, Lyon picked up India wicketkeeper KS Bharat (6) to bring up his 22nd five-wicket Test haul.
For the second Test in a row though, an Australian debutant took the prized wicket of Virat Kohli (44).
Queensland left-armer Matt Kuhnemann (2-72) broke through for his first Test scalp after umpire Nitin Menon gave Kohli out LBW.
Kohli reviewed the decision, but after a lengthy review, third umpire Richard Illingworth stuck with the on-field decision, much to the displeasure of the 34-year-old and his army of fans.
India slumped to 7-139 and appeared to be crashing to a dire position but bowling all-rounders Axar Patel (74) and Ravichandran Ashwin (37) rescued the hosts out of trouble.
Patel and Ashwin put on a 114-run partnership, the third-highest eighth-wicket stand by an Indian pair against Australia.
It took some catching brilliance from Renshaw and Pat Cummins to remove Patel and Ashwin after the dangerous pair got the home crowd back into the match.
But by the end of the play, the Indian fans were as quiet as they have been all series as Head smashed their heroes to all parts of the ground.

I reckon it'll be worth tuning in tomorrow...

Thanks Simon, I'll probably watch tomorrow :)

You and me both, Mike.
What a day of cricket.
I think you'd be hard pushed to find a match as delicately poised as that down the stretch.
What a terrific Test match.
I hope to see everyone back tomorrow.
Doesn't Renshaw have to open if he's Warner's replacement?
By Simon Smale
If Renshaw is Warner’s concussion replacement, shouldn’t he have been made to open?
- Mike
Hi Mike, that's a good question but I believe the answer is no.
The rule says the following.
The Match Referee and/or umpires may accept a Concussion Replacement on a conditional basis, for example an all-rounder replacing a batsman on the condition that the Concussion Replacement does not bowl spin or does not bowl at all.
So Renshaw can replace Warner as a batter, and given Warner is not likely to bowl, Renshaw can't either.
However, as batting orders are flexible for all sorts of reasons, they can't mandate where he bats in the line up.
Why was Head dropped?
By Simon Smale
Remind me, why was Head dropped?
- Tosh
Whatever the selectors had thought, they were clearing wrong heading into that first Test.
He was excellent just then in that session, exactly what Australia needed at exactly the right time.
I couldn't agree more

There is an old saying 'in a tight match, every run is gold'. Never a truer word was spoken.

Stumps: Australia 1-61 (Head 39, Labuschagne 16)
By Simon Smale
Well, what a terrific day of Test cricket.
This is a titanic tussle that means this Test is poised on a knife edge.
Australia might have wanted to have a bigger lead at one point earlier on today - and were in a great position to earn that solid lead as well thanks to a superb bowling performance from Nathan Lyon.
And yet India fought back, Axar Patel at the lead, scoring a tremendous 74 to get India to within one run of Australia's first innings total.
But then, with the momentum with India, Australia came back and wrested it back thanks to a man who was supposed to be too bad against spin to even warrant a place in the side, Travis Head, whose 40-ball 39 helped Australia to its 62-run lead at the close.
Terrific entertainment, more proof that this is the very best form of the game.
And boy do we have a game on our hands here.

"CATCH!" someone screams, as both silly mid off and short cover both dive as the ball passes between them. He takes a single to long off, does Head.
Marnus fends to short midwicket, but "no run, no run," is the call. He then carries on his chat with Virat Kohli, I think. They've been chatting a bit.
Labuschagne defends.
"COME ON!" I think came from Marnus' mouth as he played the shot past the diving fielder at short mid wicket. He gets a single.
10th over - Jadeja will have another
