Australia have played well and they've left the ball nicely. Khawaja has clearly come out with a different tactic against the off-spinner. I think if you win the toss and bowl, you want to be bowling the opposition out on the first day to make it count.

Usman Khawaja doesn't know whether to stick or twist against Moeen Ali. He skews the first ball over the head of mid off and then almost sweeps straight to the close fielder a ball later.

Ah. Even I could hit that! A half-tracker from Moeen is duly slapped for four. And four more! Another poor delivery but it goes straight through James Vince at backward point. Through his hands and then through his legs. The pressure is released. When does Joe Root start getting that feeling of regret?

I don't see enough of a difference in Craig Overton to what I saw in Jake Ball. It's early days, but I can't see what the difference is. When you make a call to change someone in your side after one game, for me you have to bring someone in who offers something different.

Craig Overton straightens his line but I am already fearing he is not quick enough to really trouble a batsman of David Warner's class. His final two deliveries are 82mph.

The England fans are warming their voices up. "Everywhere we gooo."

Shot! The danger of David Warner summed up in two deliveries. A drive through the covers and then a cut behind square. Both whistle off the bat to the rope.

This is exactly what England don't want. Warner to find his rhythm.

Seven of Khawaja's nine dismissals against England have been against off-spin.

Right. Now Moeen Ali has four balls to bowl at Usman Khawaja. Can he thud one into those pads? Yes! Khawaja skips down the track but the ball hits pad not bat, cue big appeals from Bairstow behind the stumps. There's not much interest from Moeen or the umpire. Khawaja was a long way down the wicket. I've not seen a replay but that was probably going over.

The big early news was that Joe Root won the toss and chose to bowl, a decision that has puzzled a few of you.

England's bowlers started poorly and bowled far too short, but, in the first full over after a 90-minute rain break, Chris Woakes ran out Cameron Bancroft for 10 with a direct hit from mid-off.

David Warner, who sent Bancroft back after initially calling him through for a single, got a roar and a stare from Stuart Broad as a thank you.

Since then, David Warner and Usman Khawaja have mixed the occasional play-and-miss with strokes of authority to keep England's bowlers at bay.

Hmmmmm. David Warner does seem to be getting a little frustrated. He goes for the uppercut over the slips to another delivery from Overton and fails to connect.

Geoffrey quips in the commentary box that Overton "isn't quick enough" to bother him but the Somerset seamer responds well with two deliveries to Khawaja, one that squares him up and another that zips past the outside edge.

More tidy stuff from Moeen Ali as he continues to keep David Warner quiet. At the end of the over Moeen finally gets a chance to aim at the front pad of Khawaja but this time the batsman sees the ball out.

Usman Khawaja averages 61 in Australia and 27 in the rest of the world.

"Caaaaatch". A bit of excitement from England as Craig Overton gets a bouncer over head height for the first time and Usman Khawaja still gets out the hook shot. The left-hander is not in control and the ball spends plenty of time in the sky but falls wide of deep square leg and rolls away for four.

More hands on heads from England. You feel they need another breakthrough.

That's the Moeen we know. That was decent.

Here is Moeen Ali but he's got David Warner to bowl at first rather than Khawaja. Not much turn but a bit of bounce from England's spinner, with one delivery catching the shoulder of Warner's bat.

A maiden to start from Moeen. Very good, accurate bowling. Warner looked to be getting a little twitchy there, eager to get the ball away.

Moeen Ali is still shadowing his off-spin in the field, desperate to get a bowl at Khawaja. For now it's Overton with his back-of-a-length bowling and now Khawaja looks as if he knows what's coming. He hangs back and just swats a pull shot for four.

The Somerset man is only bowling in the low to mid-80s mph. He will aim to up that as he gets into his spell.

How does Warner not nick them?! If I'd have played a shot like that, I'd have been mortified.I'd have been bound to have nicked it. No feet, he just gave it a whack. Is he lucky, as well as good?

The Adelaide Oval crowd are quiet for now, engrossed in this battle between the improved England seamers and Warner in particular.

That's 1-0 to Broad but just a moral victory. He floats one outside off stump and Australia's vice-captain throws the kitchen sink at a drive and only connects with fresh air. Broad can't quite believe it. He has his hands on his head, just like Alastair Cook at first slip.

It's been better bowling since the break, but we haven't actually bowled anyone out. That's a bit worrying. You can't run out 10 players. You need to get somebody out with a nick or something.

The lanky Overton charges in and already finds more bounce than any of the three England bowlers before him. His second delivery gets up a little and beats the cross-batted waft of David Warner.

The Somerset man bangs another in short and Warner takes it on. Cries of "catch" from behind the wicket but it falls comfortably wide of Moeen Ali at deep square leg.

Decent start from Overton.
