Offt. That is a beautiful piece of timing from Jason Roy.
He takes a step to leg and pierces a drive through the covers and away to the boundary.

Eight out of nine games that have been played in the evening have been won by the chasing team.
Jason Roy gets up and running straight away with a flick to deep square leg for a couple.
England have taken the knee and Sri Lanka have stood to attention.
We are ready. Jason Roy on strike. Dushmantha Chameera to bowl.
England are wearing BLUE pads over the red trousers.
A fashion crime has been committed.
Hmm...

If England lose a couple of quick wickets in the powerplay, they've got a lot of batters who haven't batted in this tournament yet.
While we're waiting for play to start have a watch of Jos Buttler pumping the Aussies all around the ground on Saturday.
Why you ask? Why not I say.

Sri Lanka have had a good start by winning the toss, and they have already played four games in Sharjah. The pitches are a bit skiddier and lower. England are the favourites but Sri Lanka have got a little positive by winning the toss and bowling first. I get a feeling something is going to happen today - but I hope it doesn't!
With India suffering a second straight defeat on Sunday to leave their semi-hopes hanging by a thread, some big names are going to crash out of this tournament in the next week.
It could be Virat Kohli. It could be Aaron Finch. It could be Andre Russell. It could be Quinton de Kock. It could be Rashid Khan. It could be Kane Williamson.
It is bubbling up beautifully.
Good question! It is wide open.
England look certain to progress, and most likely in top spot, with a win in this game all-but guaranteeing that as I've mentioned.
South Africa are in the box seat to join them because of their net run-rate. Wins over Bangladesh on Tuesday and England on Saturday would see them through unless Australia are able to turn around the run-rate deficit with big wins over Bangladesh and West Indies.
Sri Lanka and West Indies probably need to win both of their games and hope that Bangladesh can do them a favour by beating one or both of South Africa and Australia to reach the final four.
It is heating up.

England are comfortably top of this group. Sri Lanka badly need a win today.
England battered Sri Lanka 3-0 in a Twenty20 series in June but that was a Sri Lanka side in turmoil. They are more settled now, particularly in the batting ranks which is where they really struggled in that series.
They beat England in the 2019 50-over World Cup so they have history of upsetting England on the biggest stage.
The two sides have met four times in T20 World Cups, with England winning three of those encounters.
This is the first time England have played at Sharjah in this tournament.
It is a bit slower and the ball tends to skid on quite low compared to Dubai and Abu Dhabi so England are going to have be aware of that and perhaps reassess the total they need to post.
Sri Lanka captain Dasun Shanaka: "There might be dew later on so I would like to bowl. The youngsters have been amazing. It is the experience that matters. Our bat and bowlers know the conditions here."
England captain Eoin Morgan: "We would have looked to have done the same. It has worked for us so far. If you are looking to go stretch you will have to do both. We are trying to win every game at the moment. Everyone has pulled up well and is fresh."
England are wearing some outrageous red trousers today. They are bright.
They have to due to some ICC kit regulations. If India and England meet in the latter stages, they will also wear them for that match.
England and Sri Lanka are unchanged.
We'll bring you the full teams shortly.
