Malcolm McLeod: For the next Ashes series England should insist that they get to bat on the same wickets as Australia as this one appears completely different now!

I don't see this tour as a calamitous one - not the way it was four or 12 years ago, when everything fell apart.

And England's reply? Well, it's not been pretty.

Mitchell Starc had both openers playing and missing from the off, before he snared Mark Stoneman lbw, which England unsuccessfully reviewed.

Nathan Lyon then came on and cast the efforts of England's spinners into sharp relief with some even sharper turn - bowling Alastair Cook for just 10 with a peach of a delivery.

James Vince and Joe Root have steadied things very slightly since but England face an almighty battle to save this Test and avoid a 4-0 series defeat.

So a wicket that has looked utterly flat for two days might actually be a pretty good cricket pitch. Who knew?

Not England. They toiled gamely but unsuccessfully for the first half of a scorching day four, with first Shaun Marsh then brother Mitchell both completing their centuries.

Mitchell was bowled by Tom Curran a ball after reaching the landmark, while Shaun was eventually run out for 156.

More runs from Tim Paine, Mitchell Starc and Pat Cummins compounded England's misery as Australia declared on 649-7 - a lead of 303.

Vince taps one off the first, leaving Root a maximum of five balls to negotiate.

Lyon tries one more round the wicket - nothing doing, so he goes over the wicket instead.

He tries to slide the first into Root's pads but the skipper fends it away. Root then calmly plays out the rest of the over.

That's tea. Phew.

One over until the tea interval. Lyon to bowl it.

Can Vince and Root survive?

The first really banged in short ball of the innings from Hazlewood has Vince failing to weave out of the way as it cracks into his upper arm.

He's unruffled though and drops the next one into the covers for a quick single.

Nathan Lyon still round the wicket to Joe Root, who rocks back or forward to defend all six. A maiden.

Nathan Lyon finishes signing hats and bats just about in time to sprint around from fine leg to stop a Joe Root flick going to the fence. More applause - 'Garry' is currently king of the SCG.

Josh Hazlewood - back into the attack - is met with a few solid James Vince defensive strokes.

Out of ideas: Can we just forfeit and get this over with?

England are in all sorts of terrible and diabolical trouble.

James Vince calmly plays out a maiden from Nathan Lyon, using his feet nicely to smother the spin off the last.

That Lyon ball to dismiss Cook turned 5.3 degrees. Vicious.

And that's with one score of over 50!

Alastair Cook finishes the series with 376 runs at 47. It's the eighth time Nathan Lyon has dismissed him - his average against Nathan Lyon is now 25.12

Root works Starc off his pads and round the corner for two. And then does the same again.

This has a feel of desperate difficulty and carnage.

Amy Lofthouse has just pointed out that there are now a few clouds over the SCG, casting large parts of the field in shadow, after England fielded all day in scorching sunshine.

"Even the weather hates England."
