The former captain anticipates his successor's thinking perfectly.

Here comes Jack Leach for his first bowl of the day.

If I was Joe Root I'd be thinking about bringing the spin on.

England to ask for nothing but green seamers throughout the Ashes and call up retired dibby dobblers. Not sure it's the best way to build on the World Cup legacy.

Anyway, time for a drinks break. What does Joe Root do here?

Pitched Outside Leg: RE Mark Ealham's whereabouts these days, I can confirm that he is the cricket pro at The King's School, Canterbury, following in the footsteps of his father Alan. Luckily though, the school has just broken up for summer, so the ECB could maybe chance a phone call?

There's a chap in front of me wearing a Lancashire shirt with the name and number of former batsman Mark Chilton on the back. One of the more obscure cricketers you'll see celebrated in such fashion.

I think Jonny Bairstow was at fault there.

Cue a slew of messages including the name Ben Foakes.

It went exactly between first and second slip. You feel it's the keeper's catch because slip has got to dive a long way to his left.

Jonny Bairstow has got a glove covering his mouth. Fury from Stuart Broad.

Balbirnie dropped on 10published at 21.5 overs

21.5 overs

I say dropped but a healthy outside edge ends up flying between wicketkeeper Jonny Bairstow and Joe Root at first slip.

Bairstow makes no attempt at the ball and Root seemed to be moving to his right before diving to his left to try and take it one-handed.

He has hit that so hard. He has hammered that through mid-wicket - it was past him in a flash.

Sam Curran sends down a long hop and Andrew Balbirnie drives it in front of point for four.

Curran then tries an 82mph bouncer to Paul Stirling and, even if slower bowling has done well on this pitch so far, you can't serve that up.

Stirling absolutely whacks a pull shot away for four.

Hmm. It is pretty odd to see that firm an edge to that quick a ball not even reach the slip cordon.

Not the pitch England were looking for. Not that you can excuse that batting display.

That's a worry - for the wicket to not carry like that on day one, after 30-odd overs... it's not great. This wicket is going to turn.

That almost carried. In fact, it should have carried, because he went at it pretty hard.

Paul Stirling just about jams his bat down in time on a couple of full and straight Stuart Broad deliveries.

And then Stirling goes hard at one and edges it! But the ball bounces in front of second slip. That was a big edge too - not much pace in this pitch.

It feels like this goes one of two ways - Broad gets Stirling early and has his confidence restored.

Or Stirling rides his luck and starts smashing a fuming Broad to all parts.

Paul Stirling is the danger man in my eyes. England would definitely have talked about it. He has the ability to be free scoring and take the game away from you quickly.

I've played against him a number of times and you're always thinking you want to get him out early. He's such a good timer of the ball.

Paul Stirling gets off the mark by opening the face of the bat to run it down through vacant third man for four.

Stuart Broad looks thoroughly narked by that.

Ireland bring up their 50.

Sam Curran has bowled a lot round the wicket for Surrey this year - and taken a lot of wickets. Good skills.

Sam Curran gets his first ball to Paul Stirling on to the pads of the Ireland number four.

Big appeal but nothing doing - that was going down leg. Ireland pick up a leg bye.
