As it happened: Australia vs India, 3rd Test, Sydney, 2nd day

6.35pm local time/1.05pm IST: A tight last hour to stumps. Were India too slow?

5.35pm local time/12.05pm IST: Crisp half-century from Shubman Gill

Shubman Gill has managed to leave more deliveries from the Australia pacers here, than he did in the entire MCG Test. One possible reason could be that the Australians have bowled a bit short at him, allowing him that split second to make that decision. Out of 17 leaves from Gill so far, 14 have been off balls pitched back of length or short. Only three of the 13 leaves in the MCG Test from Gill were off short balls.

4.50pm local time/11.20am IST: India's opening stand crosses 50

Good contest bubbling up between Rohit Sharma and Nathan Lyon. He was content to play out a maiden against the offspinner to start with, but in his second over danced down and deposited him for a straight six. That was followed by a deft paddle-sweep for four. Lyon then responded with two more maidens, but Rohit was always itching to use his feet. A game of cat and mouse. As a little aside, Steven Smith continues to field at slip to the spinner. That had been some thought that it would be David Warner, who is managing his groin injury, to avoid too much work in the outfield but he has been stationed in the off side. For the quicks he's standing at first slip.

Take out that 90-run chase in Adelaide, and this is the first fifty opening partnership of the series from any side. India's first anyway. While these two batsmen have looked assured in defence and keen to cash in on scoring opportunities, it must be acknowledged that Mayank Agarwal did get a little unlucky. This is the flattest track of all three, and in the first 20 overs of the innings, India's control rate is 86%. The quicks have been accurate but they have hardly managed to go past the outside edge because there is hardly any seam movement to deal with.

However, that is not how India will be thinking. Whoever is out in the middle is doing their job, and that is what matters for them. Chetehswar Pujara and Ajinkya Rahane will love the prospect of batting against an older ball and tired bowlers. India will be looking at some sort of lead, at least 50-75 to cancel the disadvantage of batting last.

3.40pm local time/10.10am IST: How Smith stretched Australia

Australia's innings fell wayside after that century stand between Labuschagne and Smith: they were 206 when Labuschagne was dismissed, and on 232 when Wade had that brain fade just before the new ball was due. After Wade got out, runs dried up at one end even as Smith played as only he can, at one stage adding 39 of the 40 runs Australian batsmen scored with the bat. Australia eventually added 106 runs after the fall of their fourth wicket thanks to Smith, who scored 71 of those runs. Smith's contribution of 67% of runs after the fall of the fourth wicket is the fourth-highest for an Australia batsman in a Test innings since May 2001.

3pm local time/9.30am IST: Smith run-out, Australia all out

2.10pm local time/8.40am IST: Smith gets to his 27th century

Amid Australia's collapse, Steven Smith has his first Test century in Australia since late December 2017. Of course he missed an entire season but, still, it's been a while. After two lean Tests it is a welcome return to normal service - it was always unlikely he would be quite down for too long. He has batted at a nice even tempo with his game looking in good order and Australia will be grateful for every run he can manage from here on. He's certainly enjoying batting at the SCG this season: he scored two 62-ball centuries here during the one-day series.

1.45pm local time/8.15am IST: Bumrah with the new ball: 7-3-12-2

12.35pm local time/7.05am IST: Bumrah strikes with the new ball

12.10pm local time/6.40am IST: Wade throws it away again

Second time in three innings that Matthew Wade has been out attacking the spinner. In the first innings at the MCG he lofted R Ashwin to midwicket and now here he has picked out mid-on against Ravindra Jadeja. There is a fine line between being aggressive and being reckless. Wade was clearly intent on taking on Jadeja. Just a handful of overs before the second new ball you need to ask if it was a wise choice. Cameron Green is now potentially exposed to that challenge.

"Matthew Wade needs to have a lot more game awareness, as far as I'm concerned. In a situation like that, Matthew Wade has been opening in the last couple of Test matches so the new ball is not going to faze him. But what he's done by getting out is expose Cameron Green to the new ball, a guy in his third Test, and for mine that is just not thinking enough about the situation of the game. We talk about game awareness, understanding what's happening in the game. There was a phase there that Matthew Wade had to make sure he was there when the new ball came out."

When the new ball was taken, Steven Smith had faced 142 balls and left alone only seven balls. Only one of those leaves was outside off, that too to spinner Jadeja. With the second new ball, though, there seems a shift of plans. There were straight leaves first up. The field seems to have moved to off, and the line has got wider. India looking to test him more traditionally now.

11.55am local time/6.25am IST: Rahane's safe hands

So Australia are still waiting for their first century of the series (over to you, Steven Smith). Labuschagne could hardly believe it when he edged Ravindra Jadeja to slip. He is a player with big hundreds to his name, including a double-hundred on this ground a year ago against New Zealand. A word, too, on the catch from Ajinkya Rahane that removed him. It was a very sharp effort to a chance that came off an almost horizontal bat which are especially tough for slip catchers off spinners. The India captain is one of the best around in that position.

11.20am local time/5.50am IST: India get the breakthrough

Indian bowlers have been outstanding since 2018. Only seven centuries have been scored against them in this period across all conditions. Their planning and execution makes it very hard for batsmen to score freely. Oppositions need a lot of patience to score against this kind of an attack. For the Australian batsmen since 2018, it's been extremely hard. Across six Tests before this one, the highest individual score made by an Australian batsmen was 79 by Marcus Harris in Sydney in 2019. Labushagne went past that score with a solid innings but could not convert it into a century. Smith, meanwhile, has crossed 50. Can he get to triple-figures? Time will tell

10.45am local time/5.15am IST: Drizzle arrives but what's India's Plan B?

10.05am local time/4.35am IST: Siraj starts day two

9.50am local time/4.20am IST: More doubts over Brisbane

There's a bit of developing news regarding Brisbane, the location for the final Test, with the city going into a three-day lockdown after a person tested positive for the UK strain of Covid-19. We don't yet know if that will have an impact on this series - there have been plenty of discussions between CA and BCCI over the hotel quarantine situation.
