In a bit...
Michael Vaughan
Former England captain on BBC Test Match Special
This year is a big year for Joe Root as a captain.
This is his chance. This is his moment. He's been building for this.
In first two years in the job the focus was on white-ball cricket and winning that World Cup but now the focus is about competing in Australia in 11 months' time.
Australia will still be clear favourites, but England are getting themselves in a better position by the way they played last year and in South Africa and they are playing the right style of cricket.

Russel Arnold
Former Sri Lanka all-rounder on BBC Test Match Special
It's going to be hard for Sri Lanka - it's going to come down to approach, application and mentality and the Sri Lanka batsman of late haven't shown that.
The lead is going to grow to at least 300, and I think it's going to be really tough for Sri Lanka to take it to the fourth and fifth day.
So we'll start 15 minutes earlier tomorrow to squeeze in the time lost today.
Make sure you adjust your alarm. It's a Saturday, what else have you got planned?
Michael Vaughan
Former England captain on BBC Test Match Special
Dan Lawrence looks confident in his game.
He doesn't look overcoached - it looks natural. He's got the gift of being able to time the ball.
There will be bigger hurdles but the first challenge in Test cricket is looking like you belong there, and can play at that level, to be able to mix it with the likes of Joe Root.
From what we saw Lawrence looked like he belonged out there.
Jonathan Agnew
BBC cricket correspondent on Test Match Special
Dan Lawrence looked very composed. He looked like he belonged. One shot to the spinner had a lot of Kevin Pietersen bottom-hand.

5 years from now: Burns (35) Crawley (27), Lawrence (28), Root (35), Stokes (34), Pope (28). Looks like a pretty good top 6... then Buttler (35). And how good will Sam Curran be by then (27)?!

Sri Lanka bowling coach David Saker on Joe Root: "Joe is a seasoned player and has a really good game-plan. He understands how to play spin really well. He is always putting pressure on the bowler. Our guys haven't been good enough to combat him. That has been frustrating."
Andy Zaltzman
Test Match Special statistician
Today was Joe Root's 18th Test century.
He's failed to go from promising starts recently. He has batted at least 30 balls and gone past double figures in every innings, but then failed to go past 70, so this is welcome return to large scoring form.
It's only his second first-innings century in his last 40 Tests. Before that he'd scored 12 first-innings hundreds in his first 58 Tests.
Joe Root will rock up tomorrow in search of his fourth Test double century.
His last double ton was actually his last century before today, in the drawn Test against New Zealand back in 2019.
Phil Tufnell
Former England spinner on BBC Test Match Special
I think England have too many already. They still have all the time in the world.
Jonathan Agnew
BBC cricket correspondent on Test Match Special
It feels like England are already almost in a winning position.
I think we'll be setting our alarms that little bit earlier tomorrow.
And that, I'm afraid folks, is that.
Joe Root's having a chat with the umpires on the dressing room stairs. This might be it...

Re: Andrew Neill. Sachin played 200 Tests in 24 years. Root has nearly half that (his 98th here) in just 9 years. With more matches in modern calendars, it isn't inconceivable he might pass Tendulkar's 15,921.

Stay tuned for the TMS podcast after the day's play, Stefan. It's worth it.

Stefan Dzisiewski-Smith: So everyone on #bbccricket and @bbctms seems to be saying how great the interview with Dan Lawrence's dad is. What time was it so I can scroll back on BBC Sounds?
