There is a deep third for Joe Root. You know because of those reverse ramps!
It means he just gets a single when he opens the face and guides the ball wide of the slips.
That man is brought up for Ollie Pope so when thumps the ball in the same direction it races away for four.

With this rate England can declare before tea with a lead of 350

Incredible cricket. On paper two evenly matched teams but psychologically England miles ahead - what can the Aussies do? Frankly, who cares!

The interesting to thing will be whether Australia decide they want to join the party. Will they be happy just crawling along at two an over watching England play this way?

I'm not saying that Australia are rattled but Scott Boland - usually unerring with his accuracy - has just dragged one down short and wide to Joe Root.
The former England skipper gives it what it deserves and slaps it away through backward point for four.

Usually it's the bowler who attempts to create chaos with the batter. But England have flipped it round the other way.

Lesley Keech: Classic headology from England this morning! Bazball may or may not work every game, but it's terrific to watch. (Although possibly hard on the nerves!)
Samuel: Somewhere in Yorkshire, Geoffrey Boycott has just spat out his morning bovril watching that first over.
Matt Larkin: Rain all day tomorrow, England have to get a 200+ target on the board and bowl out Australia before today is finished. No problem

Australia have put a fielder on the boundary for Root’s reverse scoop.
It’s surely the first time any Australian team has done that in a Test?
Root 24, Pope 10
No boundaries from the over but England still take six from it.
Ollie Pope whips Pat Cummins through backward square leg and sprints back for two, then drives past extra cover for three.
A short ball ends the over but Joe Root takes it on - of course, he does! - and pulls for one.
We had to wait until the next over but Joe Root tried it again - and hit Scott Boland for six over the wicketkeeper's head!
Talk about setting the tone!
Joe Root missed with a reverse ramp first up against Pat Cummins but it was a sign of what was to come...

Lead by 68
A single from the last ball of the over keeps Ollie Pope on strike.
England have scored 33 from the first 3.3 overs this morning. Australia must be wondering what on earth is going on!?

Ollie Pope gets in on the act!
He is down the pitch to Scott Boland and punches through extra cover for four - not a bad way to get off the mark!

Another boundary for Joe Root - and this one is right out of the MCC manual.
A classical extra cover drive. No stopping that. It was gorgeous.

Image source, PA MediaI'm absolutely loving this first Test, a bold, bullish England is a joy to behold. I'd rather they lost in this manner than limped to a draw or defeat. But a victory would be my preference:)

The thing with Joe Root in Bazball is how controlled and smart his aggression is. Truly wonderful to watch.

Australia blink first again. Root's brilliance means they lose a catcher as early as the second over.
