Wood c Marsh b Cummins 24 (Eng 167-8)
The Mark Wood show is over.
We've had nine balls since lunch. We've had three sixes, a four and now a wicket. Chaos.
Wood looks to pull Pat Cummins again but sends it straight up in the air and Mitch Marsh steadies himself and takes the catch at mid-wicket.
Wood finishes with 24 off eight balls.
Cummins now has five wickets.

Headingley is as loud as it has been all day.

The fastest fifty is under threat if this continues from Mark Wood.
And again!
Short from Pat Cummins and Mark Wood, front on and legs spread, just smacks it over square leg.
England's deficit is under 100. Ben Stokes has a little smile and nod from the non-striker's end.
Trail by 102
Ben Stokes takes a single off Pat Cummins' first ball.
He wants to see more of Mark Wood too.
Tom Mallows
BBC Sport at Headingley
That has livened things up.
There was a sudden rush of fans back to their seats as news spread of Mark Wood teeing off.
They want to enjoy it while it lasts.
Jim Maxwell
BBC Test Match Special
That was very entertaining. Will Stokes step up the accelerator here? He looks a bit wounded.
Mark Wood hits two through the covers to end the over.
Wood takes 18 off five balls. Incredible.
The Chris Woakes wicket was the first ball in the over before lunch.
Andy Zaltzman
Cricket statistician on Test Match Special
Mark Wood is the first England player to hit his first ball for six in a Test since Ian Botham at Edgbaston in 1985.
He also hit his third ball for six but with a dot in between.
Matthew Henry
BBC Sport at Headingley
Mark Wood has ensured England will have a smaller first-innings deficit than they did here four years ago.
Wow!
Mark Wood backs away to leg, looking to give himself room, and Mitchell Starc goes with the yorker.
Wood can get nowhere near it so just has to agonisingly watch it, but it just misses the stumps. It probably would have hit fifth stump.
SIX!
Mark Wood has added 16 runs in three balls since lunch!!
Short again from Mitchell Starc and a top-edge pull goes over square leg.
Sir Alastair Cook
Former England captain on BBC Test Match Special
We didn't see much Bazball before lunch but it's in full flow the first two balls afterwards!
Four more!
Mark Wood backs away and slices Mitchell Starc point to the third boundary.
Jim Maxwell
BBC Test Match Special
That was extraordinary! It's as if Mark Wood was expecting the short ball and he has ripped it!
Erm.
Mark Wood has hit the first ball of the afternoon session for six.
This side man!
Thanks Sam.
I don't have many words for what we saw this morning, particularly at the end of that session. I appreciate that isn't great in my job.
Let's hope Mark Wood's good game continues, but this time with the bat?
Stuart Broad was down at 11 on the teamsheet so you'll have to wait for that, JW. Mark Wood is striding out to the middle with Ben Stokes as the players re-emerge.
I'm off to get some lunch and a lie down in a darkened room. To take you through the afternoon session is Callum Matthews.

TheJw: Can we have the Broad/Stokes partnership from Lords transferred to this afternoon please?
Simon Mann
BBC Test Match Special commentator
So much rests on Ben Stokes this afternoon, as it often does.
