The runs keep on coming. Dawid Malan, facing his first ball, flicks a poor ball from Richardson to the wide fine leg boundary.
Want to see Jos Buttler pumping Ashton Agar for two sixes? Big!
Dawid Malan is the new batsman at number three. Fast bowler Kane Richardson is into the attack.

That was a weird shot. It was back of a length and it hit high on the bat. It wasn't clear what he was trying to do. It's good carry.
Bairstow c Starc b Cummins 8 (Eng 43-1)
Australia needed this but it's not the wicket they were after. Cummins gets one to leap to Bairstow. The ball takes the shoulder of the bat and goes to Mitchell Starc, who is fielding in a strange position at a deep third slip.
At what point do Australia start to really worry? Buttler punts Cummins over extra cover sensationally. It's Buttler's sixth boundary already.
Agar is off. The majestic Pat Cummins is on.

There had been a strong advantage to teams batting first in T20s here until the past two years. In the past two years it's been eight wins and nine defeats.
Four more!
Mitchell Starc bowls a nice wide yorker and Buttler still gets it to the rope.
Buttler has 29 from 14 balls. Bairstow has hardly had a look in.
Buttler times the pants off one from Starc now. A lovely back-foot punch that runs away and into the boundary sponge.
He likes it here at the Ageas.
Ashton Agar could at least see the funny side of that start. He got a cuddle from Glenn Maxwell at the end of the over.
Jonny Bairstow clobbers one into Marcus Stoinis' flesh. That'll bruise. A decent, but painful, stop.

That is dismissive, isn't it? This is a perfect start. Agar will be out of the attack.
Buttler 19, Bairstow 4
Massive!
Jos Buttler welcomes Ashton Agar back to professional cricket in emphatic style.

I think Buttler likes the idea of Agar.
Buttler isn't going to have a look! He rocks back and clubs Agar for four more.

That's almost taken out a photographer. He was brave to not dive for cover.
Speak of the devil.
Buttler pumps left-arm spinner Ashton Agar's second ball for a mighty six back down the ground.
I think when that "big name" is Jos Buttler it's alright, no?
