Ben Stokes should be out.
He drives out to deep cover, and he opts to turn and take on the throw from Michael Neser.
Stokes is well short of his ground, but Alex Carey fails to gather cleanly and ends up demolishing the stumps with his gloves.

That was a bit like Strictly Come Dancing for Ben Stokes.
Lead by 77
Ufff.
Brilliant comeback from Mitchell Starc, firing a yorker into the toes of Ben Stokes, but the latter is able to jam it through his legs for a single.

Brutal is the right word.
Length ball, middle stump, gives himself some room and heaved it with all the time in the world.

Brutal shot and suddenly everyone wakes up.
Lead by 76
Shottt!
Ben Stokes backs away to leg and heaves Mitchell Starc through mid-wicket.
Serious shot and bat speed from the England captain.

At the moment Australia are up against it.
Mitchell Starc, who went off the field with a shoulder issue last night, is going to bowl from the other end.
Lead by 72
Five from the first over.
The sun is starting to peek through at Old Trafford. Good news.
Lead by 71
Ben Stokes gets England up and running on day three with a dab through point for a single.
Harry Brook then picks up three with a glorious drive and brings big cheers from the Old Trafford crowd.

That swipe from Stokes has told us what is going on.
Lead by 67
Ben Stokes blocks the first ball, before charging at the second and having an ugly swipe.
Any clearer on the tactics? No, me either.
Josh Hazlewood is going to bowl the first over.
Play.
Michael Vaughan reckons a lead of 200 is enough for England to win this game.
Agree?

What an ovation England are getting!
What approach will we see from England this morning?
They've often been criticised for not being able to recognise moments and go through the gears in this series, but they did that brilliantly in the last hour last night.
Joe Root and Zak Crawley got out to balls that kept low, while a couple got big on Ben Stokes.
England could have attacked and only got a lead of 120-140, but by playing slightly more cautiously they will be hoping they get a lead of up to 180-200.
Thanks Tom.
Everyone ready?
Buckle up. This should be another cracking day of Ashes cricket.
With that good news, it is time for me to take a break.
I predict some more Bazball fireworks this session. Here to guide you through it is Callum Matthews.
The hover cover, which was lurking rather menacingly by the pitch, is being moved off the field.
We are ready to go, folks.

Having relocated to Oz 12 months ago, the youngest has been packed off to bed early and me and my eight-year old daughter are getting ready for a great nights cricket! Her love of cricket started with white ball at the 20/20 World Cup semi final here in Adelaide last year which we were able to attend. Come on boys!
