Nathan Lyon resumes after drinks and Root nails a reverse sweep off his final ball for yet another boundary.
The weather looks absolutely stunning in Adelaide. I'm not saying I'm jealous, but I am considering whether I ought to go and refill my hot water bottle.

Arjun Singh: I’ve watched a lot of cricket. Root is one of the best players of spin I’ve seen. It’s been a masterclass this year especially.

There has been a a big difference between the tactics of the teams. England have been a lot more proactive. They have been prepared to score runs and play shots earlier in their innings.
Malan 43, Root 28
Have we gone back an hour? Malan drives, gets an inside edge past his stumps and sneaks a single. Please stop doing that.
He makes up for it by cutting off the back foot for four from the final ball. A lovely way to take us to drinks.

I was the only loyal one who stayed in South Australia. The other turncoats shot through.

The stand here is called the Chappell Stand but really it should be the Ian Chappell Stand.
An absolute pie from Lyon is crunched to the point boundary by Dawid Malan, who probably can't believe his luck as Lyon was building some pressure on him in the previous over.
Enjoying this aggression to the spinner.

Joe Root has now pushed mid-on and mid-wicket back. That is the way you have to play Lyon.

This is going to be a fascinating battle.
Maybe not! Root skips down the pitch to the first ball of Lyon's next over and plonks it over mid-off for four! Delightful.
He takes a single from the next ball to get Malan on strike and I think that's what we call Good Cricket.
Malan 34, Root 21
Michael Neser returns for a second spell and concedes just a single. The scoring has slowed down a little in the past few overs - the Nathan Lyon effect?
Nathan Lyon zips the ball past Dawid Malan's edge with a beauty. He just loves bowling to left handers.
Oh, now then! Joe Root plays a rather uncharacteristic slog sweep in the air that draws cries of 'catch it!' but it lands safely for a single.
Joe Root has some bat problems. He tests out a couple of spares that are offered, selects his choice and plays out a Mitchell Starc maiden.
There is no swing at all for the seamers out there today.

Root has looked positive. The run-rate has been good for England.
Lyon's first over concedes just a single.
Marnus Labuschagne is chirping away at short leg, which I imagine he'll be doing for a significant part of the day. England must be so fed up of him by now.
Meanwhile, Joe Root has just ticked off Sachin Tendulkar's 2010 tally on his quest to score the most Test runs in a calendar year.
Here comes Nathan Lyon.
He gets a huge round of applause. Not sure if it's been mentioned enough that he could be the key for Australia today.

Ex-Australia bowler on BBC Test Match Special
It is a contrast from last night. Australia would have wanted to make up the time lost last night under the lights.
Malan 33, Root 18
The crowd comes to life a little Starc bowls a vicious bouncer - but Malan sways brilliantly out of the way, bending his back like he's performing the limbo at a birthday party.

They have played very positively. It is good to see.
