Thanks, Tom.
Away from the cricket for a second as we hear the rest of Aggers' interview with Mollie King on TMS.
We've got a lot of insight on Stuart Broad's life off the pitch but nothing on whether The Saturdays will reunite. Gutted.
So, will England push on and build a lead of 300 plus? Or will Australia bounce back with a flurry of wickets?
Whatever happens you will be in safe hands as Ffion Wynne is here to guide you through the evening session.
Jonny Bairstow has picked up where he left off at Old Trafford, hitting a brisk unbeaten 34 from 35 balls to move England up to 265-4 at tea and a lead of 253.
But as has happened so often this series, England were pegged back just as they looked to be surging ahead, with Ben Stokes and Harry Brook falling in quick succession.
England were 222-3 at that stage, a lead of 210.
Joe Root and Ben Stokes led a recovery, with Root in particular bringing out his vast array of shots.
Australia made the perfect start to the afternoon session when Zak Crawley edged a Pat Cummins delivery through to Steve Smith for 73.

It has been so entertaining. But the quick wickets of Stokes and Brook gave Australia a glimmer of hope and a chance to get back in the game.
England are still in a very good position and this run rate will see them have a lead of 400 by the end of the day.

Cricket statistician on Test Match Special
England have added 135-3 in 24 overs in that session.
Root 61, Bairstow 34
Three runs off Pat Cummins' latest over makes it 43 runs off 49 balls for this partnership and takes England to 265-4 at tea.
Australia took three wickets in that session but Joe Root and Jonny Bairstow have steadied the ship to build up a handy lead of 253.

Are England cricket fans the biggest bunch of misery-guts on the planet?

Root 61, Bairstow 31
Jonny Bairstow does seem to be bristling. He knows he has the chance to take the match away from Australia here if he goes big.
The lead is 250.

I don't actually mind this from Todd Murphy. He is being brave. Because he knows Jonny Bairstow will want to go after it, if he gives it some air.
But Bairstow is really in the mood, you can see it in his body language.

That was tossed up, tempting Bairstow, but he fancied having a go.
He has spanked it high and handsome for four.
Todd Murphy tosses it up and Jonny Bairstow gobbles up the invitation, smashing the ball back over his head for four.
He moves on to 30 from just 28 deliveries.

Jonny Bairstow is flying. It's like he has just picked up from his 99 at Old Trafford.

Andrew Tomlinson: Please... if the Aussies are planning to try and return Stuart Broad's bail related shenanigans... PLEASE let it be Jonny B they try it on with.

Josh Hazlewood is not happy there. He knows he's gifted Bairstow a boundary and kicks the floor in frustration.
Root 60, Bairstow 26
Josh Hazlewood has bowled well this spell, persisting with that tricky fourth stump line. But he undoes some of his good work by gifting Jonny Bairstow a leg stump half-volley which he clips away for four.
A short ball is then uppercut over the top of the slips for another boundary.
The lead is now 244.
