Jhye Richardson slaps it through the covers and scurries two.
So 82 runs came off the last 10 overs for Australia, but 25 of them were in that expensive Adil Rashid over as Shaun Marsh teed off.
You sense the tourists are a little short against this prodigious England batting line-up.
Nathan Lyon slashes away a drive into the covers and, after a bit of a mix up, Australia settle for one.
So just one ball left for Willey to get his five-for...

Willey can't just be an opening bowler. You have to be used at the end and he's done it nicely here.
Paine lbw Willey 3 (Aus 305-8)
David Willey goes round the wicket to Tim Paine, sliding the ball on the angle past the Aussie skipper's attempted swipe and onto the pads.
England go up and it's given. Paine trudges off, opting against the review.

That's four wickets for Willey.

So just one over to go for Australia.
What can they get up to?
David Willey to bowl...

Wood has been tremendous today. He's bowled quick and got the ball reversing back in. It's really good to see his pace up.

Mark Wood works over this new pair with quick reverse swing, cramping them for room as he tails it in towards the pads.

Tim Paine flicks a full ball round the corner for one to bring up the 300 for Australia.
Polite applause from around Chester-le-Street. The home crowd will be happy with this so far though.

Send us your videos of copying that catch. I want to see the bizarre places where you do it. It doesn't have to be a ball, either. Try it with an egg.
Jhye Richardson is the new man in and has to dig out a yorker to begin.
Tremendous from David Willey - three runs, three wickets in the over.

Well no hat-trick but three in the over for David Willey!

...but Tim Paine taps it to mid-off for a single.
