England need 306 runs to win

Shot. Alex Hales with a premeditated sweep, down early and whipped away to the fence. Gets down well for such a big man.

And again! Massive six this time for Hales, who has seen enough of this single by single stuff. Into the dressing room windows almost!

Ben Sutton: Praying for Root to convert. Been getting good starts recently and getting out. Get a big one and it may open the floodgates.

Jonathan Kempster: Anyone think that that is enough testing of Mr Roy?

Mustafizur Rahman is back, can he add some excitement? Almost! Plenty of movement away from Alex Hales who did not pick that at all, it flies away off a thick outside edge and Hales is lucky to see that fly into a gap.

An 83mph leg break, basically. I can't really work out how he's gripping the ball.

Nelson - and Root is rattled on the pads, a decent lbw appeal from the visitors, but no call. That was short of length with top spin.

And he ends with a great delivery! Slid across the face of Root, a play and miss.

These two now have a hundred partnership. Wickets have been hard to come by all day.

England need under 200 more.

Steve Tredup: Seems simple - rather have the player who could be destructive (Roy) or the player is currently actually destructive (Bairstow)?

Dombacca: Come on Hales keep this going! Lets have a biggie.

Matt Tebbutt: None of the England team have a better List A average than Duckett, who is far better than Roy. He is currently smashing SA 'A' around.

Four! Nice shot from Joe Root, just leans on one again and pushes it through midwicket. Well timed.

Play and a miss! A rare moment of danger from Root, who is livid with himself. Good ball from Rubel Hossain, that moved away from the Yorkshireman.

But the 100 is up for England as Alex Hales punches a four through the offside.

How to get to 50 runs... Smash a boundary to cow corner. Rubel Hossain will not be too impressed.

Here's something to savour while there's a break in play. BBC Sport's Pint-Sized Test Match Special remembers John Arlott's best commentary moments, including Don Bradman's last Test and the Lord's "freaker".

Alec Stewart wants 120+ for Alex Hales. Over to you.

He looks in control, total control. These two are just pushing the ball into gaps and waiting for the bad ball. Making it look routine.

He took a pace down the pitch, met the bowler and won the battle.

He has to go on now, back this up, double this up. He walks off 120 not out and England win this game.

50 up for Alex Hales as he steps onto the accelerator to club the ball over cow corner for a fine four. A smash.

Hales has really improved his game. He was just hitting the ball, hitting the ball, hitting the ball, he was one dimensional.

But now he has now added a bit of finesse.

Rubel Hossain pushes one through at 87 mph, that is not hanging about!

Alex Hales pushes it for a single as the crowd chant 'Engerland!' for the first time. It's that time of day alright.

When Spidercam gets to its lowest point, I reckon that Alex Hales (a tall chap) could obliterate it with a forehand smash with his bat. I'd applaud that. It's a nuisance.

It's one of those situations where if you're batting first and you're 80-1 off 15 you'd be thinking 300 plus, but it's different when you're batting second with the pressure.

A reminder that BBC Sport will show highlights of the ICC Champions Trophy on BBC Two every night of the tournament from 1-18 June.

In-play highlight clips will also be available for UK website users, along with live text commentary.

Patience is the name of the game. Joe Root might be getting itchy feet as he takes a walk down the pitch to Mossadek and almost yorks himself.

Back to his crease for the next ball and another single.

Dave Wood: Roy's form becoming a bit of worry, but would still keep him in the side given how destructive he can be.

Jack Beecroft: I'm all for giving batsmen time but the selectors can't ignore Bairstow anymore, it's a major competition, JB for Roy.

Bangladesh have won four of their last seven ODI games versus England; having previously lost all 12 played against England immediately before this current run.

It's all very, very comfortable for England at the moment. Not the most exciting innings you'll ever see. But comfortable.
