That was superb from James Anderson.

Can Moeen keep the pressure on?

Everything is in the batsmen's favour but still James Anderson is making things happen and bowling with real pace.

Oh, and again! Now it's Mitch Marsh who is struck on the pad by an almost identical delivery. The appeal is not quite so vociferous this time. Anderson, face bright pink, all but sinks to his knees. A good decision not to review it, though - that one was definitely missing leg.

England really needed the on-field decision to go their way there. That was clipping leg stump.

James Anderson bends his back and sends down a short ball that Mitch Marsh ducks, before he's struck on the pad. Anderson pleads with the umpire, joined by the slips, but there's not a flicker from the ump. Is that sliding down leg? Joe Root decides against the review.

That delivery would have been umpire's call had England reviewed.

The last Ashes series where all five Tests went to five days was 1994-95 in Australia.

Ugh. That's short, wide and greedily smashed away by Mitch Marsh. In fact, Alastair Cook did well at slip to get himself out of the way of both bat and ball.

A single brings Shaun Marsh on strike, and he plonks his foot down the pitch and blocks his way through the remainder of the over.

Shaun Marsh just nodded to James Anderson at the end of that over there, in acknowledgement of what a good over it was.

Stuart Broad is back on the pitch but I think he's struggling with something - he doesn't look quite right. Moeen will replace Crane.

Ian West: Sitting in the shade at the back of the Trumper stand, sooooo glad I'm not out there, playing in this heat.

For all our joking, it must be so difficult to find the energy and motivation to run in and bowl under that fierce heat.

And Anderson, in a series where he's bowled more deliveries than ever before, just keeps on running in. He beats Shaun Marsh with another beauty, not giving away an inch. A superb maiden.

On a steaming hot day, when Anderson has bowled so accurately, that is not going to improve his mood.

Chance! Shaun Marsh pushes forward at James Anderson and the ball flies off the outside edge and between the slip cordon. Alastair Cook, at first slip, sticks his left hand down, Joe Root dives despairingly, but that ball has gone straight between them.

Anderson turns away, unable to watch as the ball goes racing away for four. His response is a beauty that just flickers past the edge of Marsh's bat.

Stuart Broad, who struggled to get back up after diving for a ball during Mason Crane's over, has gone off the field. He's throwing water over his hands and wrists to cool himself down.

Shot! That'll be four for Shaun Marsh as he uses his feet to clip Mason Crane away to the boundary. That boundary also takes him past the figures Shane Warne made on his Test debut - Warne finished with 1-150 back in 1992, and Crane ends his over on 1-154. He's just not quite found his rhythm this morning.

That over felt like one ball bowled six times.

There is, as someone texted in yesterday, an extreme heat policy in place at the Australian Open, which also takes place in January. Play can be suspended at the end of the current set in each match if the temperatures get above 40 degrees. There's no such ruling in cricket, though.

James Anderson works his way through another easy maiden to Mitch Marsh.

As someone who is sat inside with four layers on, it's difficult to feel sorry for m'colleagues out there in Sydney. Maybe I'm just being uncharitable.

Anyway, James Anderson will carry on.

Yes, the big boss has allowed it today.

I've just spotted that you're wearing shorts Simon. I'm very jealous.

Ooh! That turned! Mason Crane hits one of those rough patches and gets the ball to spin away from Mitch Marsh, who chases it with a huge swipe of the bat. Jonny Bairstow, standing up to the stumps, can't collect it cleanly as he ends up with a bit of dust in his eye.

Crane beats Marsh with the googly, the ball spearing just past the stumps via an inside edge, and they scamper through for a couple.
