England will be lucky to still be batting at tea. I give them just after tea at best.

Not to do Moeen and Bairstow a disservice, but that feels like the game, to me. Root was vital in this second innings. That delivery from Hazlewood nipped back into him, and the review show it was banging into middle and leg stump. Nathan Lyon speeds through his over, before Moeen clobbers him over mid-wicket for four.

Joe Root gets stuck in the crease a bit, his foot doesn't get out so he tends to play across it a bit more unlike Steve Smith.

Joe Root was struck in the face with a jarring blow yesterday but he's come back and responded well. He's playing the captain's innings that England need.

It's a muted celebration from Joe Root as he clips Josh Hazlewood through mid-wicket to bring up his half-century.

The ground stamper is back out for Josh Hazlewood. Oh, and that's glorious from Moeen. Full from Hazlewood, and Moeen just pushes it back down the ground and away for four. Moeen then puts the hearts in the mouths of the Barmy Army as he goes hooking, but he drags the ball down before meandering through for a single.

I'll say one thing for Moeen Ali - he'll certainly play a lot more positively than Stoneman and Malan against Lyon. He won't die wondering.

Down the leg side goes Nathan Lyon, and Moeen gets enough of a tickle on the ball to help it to the ropes. That brings up the 100 for England, and Moeen celebrates with a sweep to pick up a single. Root, on 49, looks to work a single and gets one on the pads from Lyon.

Ruth Brooksbank: Never mind about a new nickname for Nathan, the England batsmen need to quickly become Lyon Tamers.

Shaun Lawthom: If England want any chance here they need to counter attack, use the feet to Lyon and rotate the strike against the quicks. Knock Lyon off his length or this is game over.

Sam Rogers: England making Lyon look like Murali at the minute. Rabbits in headlights, looks ominous.

Shot! Josh Hazlewood offers up just a hint of width, and Joe Root can stay on the back foot and cut him for four. Hazlewood was aiming for that crack in the pitch, and he wasn't a million miles off. Steve Smith looks suitably anguished at slip, before Hazlewood spears in a yorker that Root digs out. Oh, and that's lovely too, an on drive that has David Warner haring after it, before he goes flying over the ropes a second after the ball does.

Mitchell Starc is out of the attack. Here's Josh Hazlewood.

Moeen and Root rotate the strike with a nurdle here and there, before Lyon and Root exchange grins as Root goes down on one knee and sweeps him past his stumps. Moeen plonks his foot forward and pushes the ball away, before he rocks back and slaps him for four! Oh, that's lovely. Width on offer from Lyon and Moeen doesn't miss out, cutting the ball to the ropes with a vicious whirl of the wrists.

Jonny Bairstow is more capable of playing an innings that changes this match than Moeen Ali so he should be in ahead of him. I'm not saying Moeen can't bat but it doesn't matter that Bairstow is better at batting with the tail, when all the other batsmen are out.

It's as daft and stupid as you can get.

I agree with Norcross. Give Lyon something different to bowl at. Make him change things up, rather than just having the lefties on toast. Let's see how well Moeen's tea tray practice sessions have paid off. He's well under the first bumper from Starc, and he can completely ignore the second as it goes whizzing down leg. Starc's only really found his lines when he's been bowling to Root. Moeen gets under two more bumpers, before he flicks a single away.

England would have been better putting Jonny Bairstow in at six here, a right-hander to nullify Nathan Lyon.

They've got too fixated with the thought Moeen Ali has to bat at six.

He might not be showing it right now, but Moeen is a gorgeous batsman to watch. He hops onto the back foot and drives Lyon through the covers for three. Root takes a bit of a skip down the wicket but he can't beat the cover fielder. It's the right way to go to Lyon, though. Root does well to get his bat on a turner, before Lyon, the least intimidating sledger you could hope to see, has a quick murmur at him.

Australia were on a similar scoreline to this in the first innings, and Steve Smith turned it around for them. Root has to do that now.

England just have to try and post something that's even a little bit challenging for Australia.
