Here are the quick hits from day two of the fifth Test between Australia and India.

1. Top order blown away

After losing opener Usman Khawaja with the last ball of day one, the rest of the top order didn’t look much better on the second morning.

Marnus Labuschagne lasted just eight balls before edging Jasprit Bumrah through to Rishabh Pant, which umpire Sharfuddoula somehow missed but thankfully the Indian review revealed the truth.

Sam Konstas was swinging at everything in sight and connected with a couple, including a reverse ramp for four, but eventually edged Mohammed Siraj to gully for 23.

And Travis Head cracked his second ball to the boundary before edging his third into the slips, leaving Australia 4-39 with debutant Beau Webster at the crease before the first hour of day two was over.

2. Michael Gough plays security and pops a balloon

Balloons, beach balls and other inflatable items are often the bane of security.

After bouncing around the sea of highly amused patrons, these often float over the fence and onto the playing arena.

Usually, the security at the ground stops it before play needs to be halted, but every now and then it makes its way to the middle.

On day two, a single yellow balloon was the centre of attention for a brief moment before being collected by umpire Michael Gough.

Did the Englishman hand it to security? Nope.

Buoyed on by the crowd, Gough provided a lighthearted moment when he used his chompers to bite the balloon until it exploded in his hands.

Gough got a small fright and smiled. The crowd went wild at the entertainment. And everyone enjoyed a moment of humour, wedged into the middle of a gripping and pulsating Test.

3. Smith falls five runs short of the 10,000 milestone

Steve Smith walked out to the crease in the middle of an onslaught of Indian bowling.

Siraj and Bumrah had their tails up and Australia needed Smith to stand tall.

For more than an hour, he did, partnering with debutant Beau Webster for a partnership of 57 for the fifth wicket.

In the back of the minds of so many was the magical number of 38.

That is what Smith needed to become just the fourth Australian to reach 10,000 career Test runs.

Smith looked good and on 33, the milestone could have been one swing of the bat away.

Alas, a good ball from Prasidh Krishna was a beauty. It pitched just outside off, seamed away and took the edge of Smith’s bat.

Smith joins an elite company of batters dismissed in the 9,990s; Mahela Jayawardene (Sri Lanka), Brian Lara (West Indies) and Alistair Cook (England).

Smith will need five runs in the second innings if he is to break the 10,000 mark at his home ground.

4. Bumrah’s disappearance

Jasprit Bumrah is arguably the best bowler of his generation, but has played just 45 of India’s 70 Tests since his debut in 2018.

Seemingly the only thing that can slow him down are injuries, including repeated back complaints, one of which required surgery in 2023.

Bumrah has carried a heavy load for India in this series — captaining twice, bowling more than 150 overs and constantly being the man called on with his team in need of a wicket — and it appeared to take its toll on day two in Sydney.

Already with the wickets of Usman Khawaja and Marnus Labuschagne under his belt, Bumrah bowled just one over almost entirely under 130kph after lunch before leaving the field.

Bumrah had a few stints off the park in previous matches to adjust his bowling spikes, but when he did not return for his next over, alarm bells started to sound.

Former Australia player and coach Darren Lehmann declared on ABC Sport that India could not win if he did not come back on the field, and India great Sunil Gavaskar agreed.

Midway through the afternoon session, Bumrah was seen in warm-up gear exiting the locker room to go for scans.

It didn’t have much of an impact in the first innings, as India took 5-44 for a four-run lead, but it will create issues if he can’t bowl in the fourth innings.

Bumrah did return to the SCG to watch the last hour of play.

5. Webster shines on debut

Beau Webster had a really good first day in Test cricket.

He took a pair of good catches and bowled well, without taking a wicket.

But with the top order struggling, Webster’s first innings in Test cricket was going to be filled with pressure.

Striding out to the middle at 4-39, he needed to face the final ball of a Mohammed Siraj over that had claimed the wickets of Sam Konstas and Travis Head.

Webster navigated the first ball and then went about his work.

The Tasmanian was the pick of the batters, top-scoring for Australia with a terrific 57 off 105.

He joins Ricky Ponting as the other Tasmanian-born player to score a half-century on his Test debut for Australia.

The day got better for the man from Snug, taking the wicket of Shubman Gill in his first over of bowling.

6. Kohli caught behind again in likely final Test innings in Australia

Australia has had one simple plan to Virat Kohli in this series — bowl outside off stump.

Kohli has been prone in the back end of his career to be dismissed, caught behind from an edge.

In this series, Kohli has played into the Australian game plan time and time again.

Every dismissal of Kohli’s in this series has been caught at either slip or by Alex Carey as wicketkeeper.

In what will most likely be his final Test innings in Australia, Kohli again was caught at slip.

Scott Boland bowled on a good length outside off and Kohli again, as he has done so often, prodded his bat and caught the edge.

As Steve Smith took the catch at second slip, Kohli was looking at the skies wondering why he fell for the trap again.

He punched his leg in disgust and marched off the SCG for just six.

7. Pant recreates 2021 heroics with blistering batting

Rishabh Pant’s efforts to save the SCG Test and win at the Gabba for India won the 2021 series and retained the Border-Gavaskar Trophy.

With his team reeling at 3-59, Pant decided the best form of defence was attack.

Pant walloped Boland over long-on for six with the first ball he faced, and then he swung harder.

Pant recorded his 50 in just 29 balls, the second-fastest in Indian Test cricket.

The fastest is also Pant, when he took 28 balls to bring up a half-century against Sri Lanka in 2022.

On a pitch that has been difficult to bat on, Pant’s swashbuckling 61 off 33, including six boundaries and four maximums, could be a match-winning knock.

He could have really taken the game away from Australia but nicked a short and wide ball from Cummins which he will feel should have flown to the boundary.
