Goodbye!

Day four didn’t panned out as many would have expected.

Australia resumed on 518-7, with a lead of 134 and Steve Smith cruising on 129, and the smart money was on the hosts batting for the majority of the first session and building a sizeable lead.

And the day did start poorly for England, who lost captain Ben Stokes to a right adductor injury inside the opening half an hour.

But the somewhat forced return of Josh Tongue into the bowling attack turned things around.

He struck with his fifth ball of the day to remove Steve Smith for 138 (caught behind by Jamie Smith) and then bowled the potentially dangerous Mitchell Starc (five) en route to figures of 3-97.

Spinner Will Jacks wrapped up the innings – Scott Boland edging to Harry Brook at first slip – as Australia were dismissed for 567, leading by 183 runs.

England’s second innings started in familiar fashion, Starc striking fifth ball to remove Zak Crawley lbw for 1.

And they should have been two down at lunch, Cameron Green needlessly diving across Smith at second slip to hand Ben Duckett a life on 38: England 80-1 at the interval.

Duckett failed to capitalise on his reprieve – bowled for Michael Neser for 42 – before Boland removed Joe Root lbw for 6.

But Jacob Bethell stood firm, steering England to 174-3 at tea alongside Brook.

The opening 45 minutes of the final session were full of joy for England. Not only did their fourth-wicket pair overturn Australia’s lead but Bethell registered his maiden first-class century! He took 18 deliveries to advance from 96 to three figures but got over the line in style, hitting Beau Webster for four.

Unfortunately, the joy was short-lived. Two overs later, Webster struck twice in three deliveries to remove Brook and Will Jacks. Brook was trapped lbw while Jacks holed out to a diving Green in the deep for a two-ball duck.

Smith, Stokes and Brydon Carse also fell before the close with England 302-8 overnight, leading by 119 runs. Bethell has 142 (232) and Matthew Potts has 0 (10).

If Brendon McCullum is a stubborn coach and you have your methods, he is going to get found out. He wants the England team to play the way he used to play.

If you play one way, the opposition will find you out. Bazball has been found out. The Test team can improve and England cricket needs more detail and a more professional approach.

This team has been loose on this tour - they need to sharpen up. The management needs to accept that it needs to change slightly.

England batter Jacob Bethell to TNT Sports: "I feel pretty good. Still hasn't really sunk in but to have the family here and watching was pretty special. I think they enjoyed it - my old man probably held off the beers for a few hours there, but hopefully he'll be having a couple tonight.

"In the nineties I felt okay to be honest. I was a little bit nervous, but nowhere near as nervous as I was in New Zealand when I forgot to watch the ball and got out. All I was focusing on was watching the ball and playing it. Actually when you're out there you feel okay. Everyone else who has no control feels it more than you do. My dad is an emotional guy, but I didn't think he would be that emotional. It's pretty cool to see that.

"The blue print [for red-ball cricket] is that in terms of these conditions. Obviously conditions will change throughout, when we got back to England and stuff like that. I found a real nice zone in terms of scoring and being able to throw a punch without taking too much risk which is pretty good. That will be give the world of confidence, especially as people will stop talking about it."

Australia's Usman Khawaja speaking to Test Match Special: "I am very grateful to have played for such a long career. Not everyone gets to retire on their own terms so I am very happy.

"I just want to win. It will be nice to go out on that and do it well. I can relax after tomorrow and one last push.

"It is ours for the taking, to chase the runs down. We let them go in the second session but we cracked it open after that. It was looking dicey for a moment.

"There was emotion coming out to bat and that was one of the hardest batting innings. I wasn't expecting to face Jacob Bethell either! It was hard to calm myself down."

"The baggy green means so much to me so it is one of those things that you cherish. I am attached to playing cricket for Australia and that is what I will always hold close to my heart."

Jacob Bethell's innings was a technical masterclass and a real strong mentality of calmness. Surely this sends the message to many in the English game.

The best players in the world stay in second and third gear in Test match cricket. Fourth and fifth gear are far too risky. You don't need to dance down the pitch.

It is a lesson for Harry Brook to calm down. He is getting bored batting. Just bat for a few hours and see where it takes you.

England's Jacob Bethell speaking on Test Match Special: "It was very good out there. It is just one of those wickets that getting past the new ball, it is nice to bat on. You just had to concentrate."

On being on 99: "It was goosebumps when I got over the line - there were nerves but I have made the mistake of stopping watching the ball. I carried on playing like I had throughout the innings."

On his calmness: "A big contribution is that I was small growing up. I had the ability to bat for long periods when I was younger and that is instilled in me throughout.

"The new ball is around the corner and will pose different challenges. I will try to hit in the gaps and play smart. Before we went out to bat, we wanted a 200-run lead. Tomorrow we will try to get as near to that."

On what captain Ben Stokes said to him: "He said well played. I haven't chatted to anyone properly yet but I am looking forward to batting with the boys.

"It is special to have family here as well."

Brendon McCullum has got to change. This team have not won a five-Test series on his watch.

The methods that he has brought and the psychology, England have not coped with the pressure. He needs to be honest with himself.

He can change if he is not stubborn. He is a young coach and if he is willing to change, I have no problem with this combination carrying on.

Australia all-rounder Beau Webster speaking to the host broadcaster: "I certainly didn't think it [making an impact] would be with the spin in this game but that's the way it goes. There was a bit of wear and tear from Mitchell Starc's footmarks and we managed to make the most of it in that session.

"I just tried to bowl my best ball. I don't bowl them a hell of a lot to be honest. I think the less I bowl the spin in the nets the better. So when I do get them out in a game I'm not thinking too much and just try to hit the right area. We were lucky enough to get a couple.

"I wasn't expecting Will Jacks to be that aggressive. I got lucky there with an inside edge but I got a bit of bite out of the rough and a hell of a catch by Cameron Green. He's taken a stunner there.

"I loved batting here. It's a really nice place to bat. Obviously the big scores have reflected that. I feel in good form and I've carried my form from the West Indies through to the start of the Shield and then here in the last Test. I just tried to make the most of it.

"We are very well placed. They have a lead and we'd like to mop up these two as quickly as we can with the new ball round the corner as well. Not sure I'll get a run in the morning to snag a five-for. Hopefully the top-order boys will get the job done."

We have seen Jacob Bethell dancing down and playing Bazball because that's what he felt he needed to do. But we saw none of that today. We saw a little bit at the end when he was with the lower order, but up until about 120 he was playing every single ball on its merits. He had to work bloody hard for it.

Every time Scott Boland and Mitchell Starc missed, Jacob Bethell scored in a low-risk fashion. If you can do that often the odds are more in your favour. I think he learnt his gameplan in four-day cricket - in Test cricket - today on one of the biggest stages. There's learning cricket and learning cricket. He's learnt his method in the biggest stage. It's not easy what he has just done there and he should be unbelievably proud of it.

Here are some of the best moments from Jacob Bethell's landmark century, which came off 162 balls and featured 13 fours.

He's unbeaten on 142 (232) overnight.

This is the biggest smile I have had on my face for a long time. Jacob Bethell has played in a way that Test match cricket has been played for many generation. He had good balance and a good technique. It was a masterclass in technique and composure.

It was a tricky pitch. The ball was moving around but the stroke play was brilliant - he did not try to over-hit it. He let the ball come and just caressed it.

Give me a Jacob Bethell over Harry Brook any day in Test match cricket.

Jonathan Agnew
BBC Chief Cricket Commentator on Test Match Special

Jacob Bethell is lucky to be playing now instead of last summer when Bazball was going crazy. He did not play a crazy shot at all.

He has remodelled himself to play to the occasion. He can come in now play how he wants as things are changing.

Simon Mann
BBC Test Match Special commentator

Australia look on course to win this game but this has been Jacob Bethell's day. Such a memorable day for him.

The game is not done yet but it feels like it will be 4-1.

The evening session belonged to Jacob Bethell, who brought up his first Test century - and his maiden first-class hundred - to ensure Australia would at least have to bat again.

It was an tense watch seeing him get to three figures, though, even if the 22-year-old himself was a picture of composure at the crease.

Bethell creeped through the nineties but eventually skipped down the pitch to Beau Webster and whipped him over long-on to reach the milestone in style.

Webster ended up proving exceedingly effective, though, as he captured the wickets of Harry Brook and Will Jacks in the same over.

Brook's brain had started to become scrambled, and he was trapped lbw for 42 - given on review - while Jacks played the daftest of shots to go for a duck, caught in the deep.

England then lost three more wickets before the close.

Jamie Smith was run out after mix-up with Bethell while injured skipper Ben Stokes and Brydon Carse nicked off to slip off the bowling off Webster and Boland, respectively.

Bethell reached stumps unbeaten on 142 while Matthew Potts is nought not out as England closed on 302-8 - a lead of 119 runs heading into the final day of the series.

Ben Duckett failed to capitalise on his let off - bowled by Michael Neser for 42.

England then lost first-innings centurion Joe Root, who was trapped lbw by Scott Boland for six after a scratchy innings.

But Jacob Bethell stood firm, steering England to 174-3 at tea alongside Harry Brook.

England began day four with an injury. Captain Ben Stokes suffered a right adductor issue inside the opening half hour and had to leave the field.

But Josh Tongue struck twice in quick succession to remove Steve Smith (139, caught behind) and the dangerous Mitchell Starc (5, bowled) and Will Jacks accounted for Scott Boland to end Australia’s innings without too much lower-order chaos.

From 518-7 overnight (leading by 134), Australia were bowled out for 567 to lead by 183. Beau Webster was unbeaten on 71.

It was a familiar start to England’s second innings, Starc striking fifth ball to remove Zak Crawley lbw for 1.

And they should have been two down at lunch, Cameron Green needlessly diving across Smith at second slip to hand Ben Duckett a life on 38: England were 80-1 at the interval.

Righty-ho. I'm cool, calm, and collected again.

Let's take a look back on an action-packed day four which started with Australia batting and ended with a Jacob Bethell-led England clinging on.
