Moeen Ali is making sure I'm on my toes late in the day by racing through another over at the rate of knots!

Just two from it. The England off-spinner has done a fine job for his side in this innings.

Mitchell Marsh might not be going quite at the rate he did yesterday - yesterday! This game is in fast-forward - but he still took a couple of fours off Stuart Broad a couple of overs back...

You just feel that Marsh is crucial here for Australia.

Another maiden. Australia are being very watchful late in the day.

One more for England before stumps would be huge.

Meanwhile, the physio runs out to have a look at Jonny Bairstow's face after that blow in Stuart Broad's last over but the England wicketkeeper quickly dismisses him.

Mitchell Marsh gets a thick inside edge onto his pad off Stuart Broad.

The Australian reaches down to pick it up and immediately a cry of "howzat!?!" goes up in the Western Terrace.

Can you imagine!?

England would take that, Tony!

Moeen Ali gets through a maiden with Travis Head repeatedly going back but punching the ball straight to Ben Stokes at short extra cover.

The last half an hour here England will want one more.

Four more to end the over. More width from Stuart Broad and Mitchell Marsh is able to cut it away down to deep third.

The ball before, Broad nipped one back and got an inside edge. It bounced well before it reached Jonny Bairstow, who saved the boundary with his left mitt but gets a whack in the face for his trouble.

Off his glove, into the chops. Ouch.

That's a lovely shot from Marsh, as soon as it beats the infield it races away for four. It was too wide from Broad.

We saw plenty of that in Australia's first innings.

Mitchell Marsh gets on the front foot and just leans on the ball to send it racing through the covers for four.

Is it a send off if you're thanking the batter...?

Change of bowling for England. Chris Woakes is off and Stuart Broad is on.

What can Mr Ashes conjure up before the close?

Nearly a mix-up as Mitchell Marsh presses forward, defends into the off side and sets off for a single.

Travis Head isn't interested and sends him back with Jonny Bairstow scampering from behind the stumps to collect the ball.

Marsh is back comfortably enough in the end. The last thing Australia need now is a run out.

Australia will know how key this partnership is.

Chris Woakes spears one in at the stumps to Mitchell Marsh and raps the front pad.

There's an appeal for lbw but Woakes isn't convinced. It was sliding down leg and he knew it.

Marsh is off the mark with a single to square leg and Australia take three from the over.

I’ve been sat next to a big group of touring Australia fans for the last 30 minutes or so. They were feeling fairly chipper but all of a sudden they look a bit concerned.

“That was the big one,” one of them said after the Khawaja wicket.

Feels like it.

The plan is working well for England, they are just waiting for Australia to make mistakes.
