Buttler unbeaten with 64 at the close
England slump from 130-2 to 226-8
Root - dropped three times - is bowled by Cummins for 57 to bring about collapse
Four wickets for Marsh and two each for Cummins and Hazlewood
Australia - 2-1 up in series - have already retained Ashes
Australia won toss; 5th Test, day one, The Oval
Siddle sneaks one onto Root's pads but the appeal is stifled. There were two noises but replays show it was the ball flicking both pads rather than an inside edge. That might have been closer than it first appeared.
The Australian drops short again a ball later and Joe Root helps himself to an easy three runs.
Peter Siddle is brought back into the attack after his sketchy first spell. He gets up to the crease but has to pull out as Joe Root backs away.

The PA announcer has just told us about the drone camera that is flying over the ground. Sure enough, it's hovering near the gas tower. It's nice to get reassurance that it's supposed to be here, rather than Joe Root's footwork being spied on by Russia.
Burns 28, Root 18
An over with no drama for England, bowled by Pat Cummins. Cummins is the leading wicket taker with 25 in this series. He's six clear of Stuart Broad in second.

Glenn, you can't not be biased.

Not being biased now but I'd say that 3-1 would be a fair reflection of the series.
Pat Cummins is back.

I'll be honest, I was a bit concerned that this Test could end up being flat; that there'd be an end of term hangover for both sides and the crowd would feel it. That hasn't been the case this morning. It's packed here, a pleasant murmur running around The Oval, and lots of talk of the "crucial first hour" being navigated "pretty well" by Burns and now Root. Root crunching an absolutely glorious drive for four every now and again helps, as well.
Burns 28, Root 17
More swing for Mitchell Marsh but it's too straight and Rory Burns climbs in, driving nicely down the ground to the boundary.
The conditions feel typically British. There's movement in the air but at Marsh's usual pace of 82mph it's comfortable. There's a traditional hum around the ground too.

We need an opener who's going to take up deliveries and see off the new ball in order to protect the middle order. I'd be looking at Dom Sibley or Hassan Azad.

The speed gun has just clocked a Mitchell Marsh delivery at 89mph. He's either put his spare time to good use this summer or the gun is faulty.

If Australia go too hard looking for wickets, rather than just bowling good areas like they have done in the rest of the series, England could get away from them.
Burns 23, Root 16
It has been a success regardless of the result in this match for me, but I know many people disagree. England did something they had NEVER done before in winning a World Cup.
Hazlewood continues and Root flicks a couple more off his toes.

Exam question on our cricket WhatsApp group this morning: 'If England win this fifth test the summer can be considered, on the whole, a success. If they lose, it will have been neutral. Discuss'. Consensus seems to be that unless we had been thrashed by Australia, the first WC win makes the summer a success whatever. Would be interested as to the thoughts of the readers.

Joe Root has been unfortunate to get some very good deliveries this summer, but he has occasionally made them look better because of footwork that has left him stuck on the crease. This morning it's been noticeable how he has tried to get forward, batting out of his crease and taking a big stride. Just beware the bouncer...

There's a bit of swing for Mitchell Marsh but he's no Josh Hazlewood, Pat Cummins or Mitchell Starc. The batsmen have a bit more time to get in behind it.

Re 11:47 Steven Green You talk about dropping Denly, but who to replace?? There's a distinct lack of quality English openers who have the form to justify replacing them. His 53 in the second innings suggests to keep faith.

Mitchell Marsh is bowling the first over after drinks. That probably tells you it has not quite worked for the Aussie bowlers so far.
Burns 22, Root 13
Josh Hazlewood restores a bit of order with a maiden. That's drinks. Tim Paine might have a quiet word with his troops.
