Roy taps a single to long on before Aponso finds a bit more bounce to Hales, who deflects it away safely enough.

Another single to finish for Roy and that's a big over for England - 13 from it and back on the front foot.

Amila Aponso had been building some pressure with dot balls but Jason Roy sees mid-off is up and smacks the spinner down the ground for four.

Sri Lanka keep the same field and so Roy marmalises the next ball for six! Tremendous power, clearing the boundary with ease.

Lasith Malinga sends down a low full toss that Alex Hales can only just jab his bat down on. For most bowlers it's a poor delivery or a mistake but it's incredibly effective for the Sri Lankan as he gets so much dip on it that it often foxes the batsman. Akin to a sinker or maybe even a 12-6 curveball in baseball.

That's not effective though - Malinga strays short and wide and Hales whacks it through backward point for four.

FiGJaM1175: Got dropped from the school cricket team after I put a fork through my foot whilst digging potatoes during a gardening lesson.. (yes, we had gardening lessons at school).. and yes, ouch.

The dots continue as Amila Aponso wheels through five nagging deliveries that Alex Hales can't work away.

The last is down leg though and Hales clips it through leg for one. Good comeback from Sri Lanka after those loose first two overs.

When you are out of the team you never wish an injury or poor form on your teammates but in some ways you do. Anya Shrubsole took that six-fer in the World Cup final and I was thinking 'that should have been me'. It is a real mental challenge.

Lasith Malinga checks that progress with five dot balls before he slides a wide down leg.

The proper sixth delivery is a dot too though. A fine over from the wily veteran.

Shot! Alex Hales just leans into the final ball of the over and caresses it through the covers for four.

England making rapid progress to start this chase.

And Alex Hales gets off the mark first ball with an easy drive to long on. A gift from Sri Lanka that.

This is an opportunity for Alex Hales. When you get an opportunity through injury you have to take it. Bairstow and Roy have been outstanding for England. They haven't looked like a bad run of form. Hales has to remind everyone what a good player he is.

Slow left-armer Amila Aponso will open the bowling from t'other end.

Malinga responds with two dot balls to end an eventful first over.

Shot! Three fours in a row and the first off the bat is a peach, Jason Roy clattering it through cover point.

Make that two leg-bye boundaries in a row. Malinga slings it down and the ball swings and bounces away from Dickwella to the fence.

Not the best keeping there.

That ball was revealing. It rolled along the floor. This is the challenge England need. It is not going to be easy.

Ugh. The second ball keeps very low, sliding under Jason Roy's miscued drive and nutmegging Niroshan Dickwella before racing away to the boundary.

Cheers Matt.

It's Lastih Malinga to Jason Roy first up and the Surrey man covers up in defence.

Anyway, Hales now has his chance to stake a claim for Bairstow's opening batting spot.

The England openers are out in the middle.

Here's Jack Skelton to talk you through the first half of the innings.
