Wow. Carey gave that some clout.

I'm never quite certain where I stand on the 'Root is good enough to be England's first spinner' debate. He bowls some good balls but often struggles to stop the scoring. One is too short and then the next too full, Carey thumping it back over the England captain's head for four. The final ball is overpitched as well. Smith drives to the fence.

Expensive over.

Australia have looked a bit more proactive since the break. Joe Root has bowled well, but they're just trying to milk him here.

They'll have one eye on the declaration from here, either just before or after the evening session.

Things could have got really ugly for England after that Labuschagne no-ball 'wicket'. It's to their credit that they didn't fall apart afterwards. It's still a really bad look.

Anderson is probing away to Carey but is yet to make Aussie hearts flutter in this spell.

If you're just joining us, it's not all doom and gloom this morning.

England are clinging on - Australia have gone from 221-2 at the start of the day to 316-5.

Marnus Labuschagne turned his overnight 95 into a maiden Ashes hundred. It was followed by some classic England calamity when he was caught behind by Ollie Robinson on 102 that turned out to be a no-ball.

He was eventually out lbw to Robinson for 103 and followed back by Travis Head for 18 and Cameron Green for two.

But Steve Smith is still there on 60 - a slight understatement to say he's the wicket England need.

It has been quiet in the 20 minutes since the break. England look to be relying on a break in concentration to add to the three wickets they have taken...

Wickets are important but England have got to keep stifling Australia for runs too. It means they have to keep thinking more about when they have to declare and it delays that decision further.

Ben Stokes applauds as Anderson runs in again. Jimmy flicks his hair, mostly brown with some flashes of grey, out of his eyes at the end of the over. Carey looks solid.

I love Jimmy's reactions on the rare occasion he bowls a bad ball. It's like total disbelief that a bad delivery has dared come out of his own hand.

It's fair to say Finny has got that very wrong in these conditions. A decision like Joe Root at the toss in Brisbane. Ever made a similar mistake?

I have got the dress code completely wrong. I wore shorts yesterday and today have jeans and a thick grey t-shirt. I don't know how acceptable it is to take my trousers off in the commentary box.

We're told by those in Adelaide that it's like this game is being played in an oven today. It's actually overcast but the wind is blowing straight off the desert. Anderson limbers himself through a maiden.

A long chase for Jimmy Anderson. He won't like that but it'll loosen him up to bowl.

Alex Carey, a batter who has shown in T20s he can certainly biff it, reverse sweeps his first ball after the break off Root. That's a clear sign of intent from the Aussies. They're busy in the rest of the over, a consequence of the field being spread widely.

Jimmy Anderson looked stiff chasing the Carey shot in that over but is now going to bowl.

Joe Root begins proceedings with the ball. Steve Smith's wicket looks as huge as ever.

An interesting afternoon lies ahead. We'd expect Australia to try and press on, but there's not loads of batting left for them.

Here come the players.

Is this a cliché big first hour? I'd say so.

The expectation was at the start of the day that Australia would aim to declare later on and have a bowl under lights and England's top order.

You'd think they'd want 450 before declaring so it will be a race against time for them too in their push to be bowling in prime conditions.

I didn't like the ball from Root that went through the top of the pitch and hit the glove. That was ominous.

The second (evening) session will get under way in 10 minutes time. If England are to win this match you'd think they'd have to bowl Australia out before the next break, possibly in the next hour.
