He just prodded forward, playing for a bit of turn, and the new, shiny ball has just moved on. It's a nice, sharp catch at slip.
Curran c Thirmanne b Embuldeniya 13 (Eng 252-6)
Gone this time.
Curran leans forward onto the front foot but the ball doesn't turn, takes the edge and goes to slip.
That's the last ball before tea.
This will be the last over before tea. Root takes a single to give Curran the strike back.

Sam Curran hit that hard and high. What a fine shot.

Hello Sam Curran! He has had enough of blocking. He launches Perera into the stands.
Sri Lanka Mickey Arthur is flapping again. I've no idea why. The ball tracking only had the ball flicking the top of the stumps.

Mickey isn't happy. He can't see much from there!
It was close but Sam Curran survives! It is umpire's call on height. Relief for England.
Ooo. There are a few small squiggles as the ball passes the bat but the third umpire doesn't think he has hit it.

The new ball does skid on to the batsman.
Curran nervously looks towards the big screen. We're waiting for the technology...

It looks high.
It has hit Curran on the back thigh. Height could save him.

It might be out - but I certainly wouldn't consult Dickwella in these situations.
This is close. Sam Curran is hit on the pad. The umpire says no but...

Mark Poole: This is all we ever wanted from Root. Converting more of his 50s into 100s. When he does this he belongs with the best.

Two runs to Curran via the outer part of the bat to end Embuldeniya's comeback over.
The new ball is taken immediately. Spinner Dilruwan Perera has it in his hand.

Sri Lanka absolutely have to take the new ball. We saw what the left-arm spinner can do with a new ball.
Lasith Embuldeniya is back. The left-arm spinner has 4-95 so far.

Root's away average is better than both Kohli and Williamson. His overall average is lower purely due to batting in harder home conditions.
