England are playing with fire.

You would back a fielder of the quality of Marnus Labuschagne to catch that.
Eng 244-4
Harry Brook takes on the latest Pat Cummins bouncer, thumps it to square leg... but Marnus Labuschagne drops the catch!
He really did middle it, it went very quickly and I'm not even sure if Labuschagne got a hand to it - the ball just bounced off his wrist/ forearm!
Let off for Brook and England.
Harry Brook gives himself room and thumps Cam Green into the gap on the off side for three.
After that it is a fairly standard - what even is that anymore? - over of Test cricket as Ben Stokes blocks and leaves for the rest of the over.
Given all the runs Joe Root has scored for England over the years - even already in this series - you feel you have to allow him the odd error in judgement.
But this did feel like a particularly needless dismissal...
Smith's catch removes Root for 10
This is getting pretty graphic for England...

That's the most orthodox shot we have seen for about an hour and a half.
The over ends with Ben Stokes being hit by a bumper from Pat Cummins. It hits him on the right bicep but the England skipper just shrugs it off.
Despite that, it feels like there is finally some semblance of calm returning to the match.
Stokes nailed the ball through mid-wicket for four the previous delivery and there was even a fuller delivery bowled to Harry Brook earlier in the over.
It may just be a brief period of calm before the madness returns but it's something!

With Harry Brook on strike anything could happen.
With Ben Stokes looking to wait out the short stuff, the field changes ever so slightly.
Cam Green still ends the over with a bouncer but it didn't take long for Australia to change their approach - with the field, at least - when an England batter finally decided against taking on the bumpers.

Image source, ReutersAstie Bolton: Relentless short balls and waiting for England to lose a wicket isn't entertaining (if you're English). BazBall or not.
The next one is a legal delivery but Harry Brook shuffles leg side to give himself room and heaves it over mid-wicket for four!
Similar approach next up from Brook, Cameron Green goes full and the ball is a whisker away from leg stump.
There is something happening every ball!
Cameron Green - who started this whole bouncer ploy - is back on and starts with a no-ball.

England have got Australia back into this game by throwing away some wickets in this last hour.
It seems sacrilegious at the Home of Cricket to see this sort of baseball tactic being deployed. And it is not a successful one at the moment.
Another leave from Ben Stokes to another Pat Cummins bouncer.
It was very high once more but we may just be seeing a different approach from Stokes.
Harry Brook has shown little sign of wanting to back down, though...
Is the captain going to be the one to decide enough is enough and just try to see off the short stuff?
Possibly. He leaves the latest bumper from Pat Cummins. But it was very high so reaching it would have taken some doing.

Absolutely pathetic cricket from England to constantly fall for these Aussie tactics that are so obvious on a pitch that isn’t doing much after they’ve just lost their main spinner. Baffling.
Alex, Bromsgrove
Muppets. Australia are there for the taking. Lyon is possibly out of the game, if not the series. Why give them a chance?

There's an old saying in sport, that you should always do what your opponent does not want you to do. Australia want England to keep hooking these short balls.
Mark, Manchester.
Pat Cummins brings himself into the attack and joins in with the bouncer barrage. Well, the field suggests he will anyway.
