You could say that England got the 'rub of the green' with that decision eh?
Tom in Kent
Very nice, Tom.

Former England captain on BBC Test Match Special
Fantastic. Duckett has got great balance, scores on the offside and the onside. Duckett just glides it, he had a bit of fortune, Cameron Green missed one and there was lbw overturned, he's a lovely timer of the ball.
He sets himself to score off every ball. I think that's the best I've ever seen him play.

Damien Fitton: Clean catch for me. He's in full control of the ball before he drops down to his knees.

The Australia players are still complaining to the umpires as they get to the pavilion steps.
Michael Vaughan
Former England captain on BBC Test Match Special
I'll be honest with you, I thought he caught it. But I saw the message from Marais Erasmus and he was in control of the ball but not of his body.
Rules are rules. Sorry, Glenn!
Target 371
Snorter from Cameron Green with two balls left in the day but Ben Stokes just about gets his bat out of the way in time.
A maiden to finish an excellent day for Australia but they are walking off absolutely livid.
Ben Stokes is unbeaten on 29, Ben Duckett, rather more controversially, is still there on 50.
Another quiet day of Ashes cricket.

Jacob Wadsworth: How can anyone even contest that decision? When, in the history of this game have you been allowed to drag the ball along the ground after catching it? It's the most obvious not out going.
One over left in the day. Ben Stokes is on strike to face Cameron Green.
England still need another 257 to win, Australia need six wickets.
Glenn McGrath
Ex-Australia bowler on BBC Test Match Special
England have the best of the conditions and now they are getting the best of the rules.

Mitchell Starc looks to be ranting at Ben Duckett now as he walks past him back to his mark. Duckett stands with his arms outstretched as if to say "it's not my fault".
Lord's is suddenly fired up.
Target 371
Of course, Mitchell Starc is now bowling and to say he is fired up is an understatement.
Ben Stokes isn't getting involved, leaving any bouncers and then digs out a yorker for a single to mid-on.
Also, if you're at Lord's, I'd stay out of Glenn McGrath's way if I were you...

Nick Henderson: That's a clean catch for me.
Jon Evans: That couldn't be more obviously grounded on the replay. Amazing that Starc thought otherwise really.
Jonathan Agnew
BBC cricket correspondent on Test Match Special
I love you to bits Glenn, but that is out, sorry, not out.
Glenn McGrath
Ex-Australia bowler on BBC Test Match Special
If that's England taking that catch, that is out!
Target 371
Well that has spiced things up with five minutes left in the day!
Australia are spitting feathers - so is Glenn McGrath in the TMS commentary box.
That won't be the last we hear of that one.
Matthew Henry

Now then. The boos turn to cheers.
Marnus Labuschagne stands with his arms outstretched.
It takes a lot to get Pat Cummins wound up but he's having a long word with the umpire. I think bowler Cameron Green is using his shirt to hide the angry words he's saying.
Glenn McGrath
Ex-Australia bowler on BBC Test Match Special
That is the biggest load of rubbish that I've ever seen. If that's not out, every catch I've ever seen taken should not be out. That is a disgrace. I've seen everything. That is ridiculous.

He has! Not out!
Ben Duckett tried to ramp a short ball from Cameron Green, the ball came off the back of the bat and carried all the way down to Mitchell Starc at fine leg.
He takes it cleanly but put the ball on the ground as he lands - and it's given not out!
Controversial but a reprieve for Duckett, who was halfway off, and Australia are furious. He Lord's crowd are loving it.
Phil Tufnell
Former England spinner on BBC Test Match Special
It was under control, but then he rubbed it on the ground.
Fifty and out for Ben Duckett. Or is it?
Has Mitchell Starc grassed it at fine leg?
