Bairstow st Carey b Lyon 78 (Eng 297-6)
Nathan Lyon gets his revenge!
Bairstow takes a couple of steps down the pitch, looking to attack again, but is deceived by Lyon's crafty flight and Alex Carey does the rest.
A fine innings, as Bairstow raises his bat and soaks up the Edgbaston applause.

Since tea, Jonny Bairstow has just gone and the Aussies have just offered him that width. It's got him into that momentum.
Bairstow has now caught up with Joe Root, helping himself to four more as Nathan Lyon drops too short.

James: Jonny Bairstow in this mood is an absolute joy to watch.

He's going now. Jonny is starting to motor. Hip high, on the leg side. It's times like this when you look at Hazlewood, flat pitch, he's not played a lot of cricket. That catch is crucial.
Root 77, Bairstow 74
Salt, meet wounds.
Bairstow pulls Hazlewood for four more.
Big, big over.

It was in, it was out. They rush back for a couple. A big moment.
Eng 288-5
Jonny Bairstow crunches a glorious drive through the covers... but is dropped next ball!
A tough chance for keeper Alex Carey, diving full stretch to his right, but it seemed to stick in the glove before popping out as he hit the deck.
With no first slip, he had to dive a long way.
Wow. How costly?
A year out of the game?
No bother at all.

Cricket statistician on Test Match Special
The 100 partnership came up in 20.5 overs, it is the 11th 100 partnership between the two. They average just under 51 together per stand.
Root 77, Bairstow 64
Bairstow skips down the pitch and whips Nathan Lyon through mid-wicket for yet another boundary.
A bit of Kevin Pietersen flair about that one.
How good is Bairstow to watch at his best? He's catching up with Joe Root here, as they reach their 100 partnership in absolutely no time.
Here's the first outing of the circle thing for the ball to fit through.
It passes the test pretty easily.
On you go, Australia.

What a fantastic day okay so far. Gripping stuff every ball. I cheered a four in the school playground whilst picking up kids up earlier. I got looked at by the other parents. “It’s the Ashes” was my reply.

Josh Hazlewood is a class act.
Just a single from his over as he continues to probe away at a good length.

It’s getting lively…

I can't tell you how good a shot that is, to chip the ball over mid-off, it's really good batting. He really seems to be in control.
And again! Four more lofted over mid-off.
Edgbaston is rocking, and Jonny Bairstow is loving every moment.

That has gone past Marnus Labuschagne at short leg like an absolute rocket. He's jumped and ducked, almost into it. It almost feels like a free shot for him.
Here we go!
Bairstow sweeps Nathan Lyon firmly for four.
He's in the mood, indeed.

Image source, PA MediaA really valuable knock with not much cricket behind him, he's fitted seamlessly back into the role. He knows how important this would be to go on and get the big one.
