Fantastic diving stop from mid on by Dilshan Madushanka to deny Shakib Al Hasan another boundary.
The fast bowler has been excellent again but, as has been the case for much of this tournament, his fellow bowlers don't look half as threatening.
Target 280
For anyone concerned that there is not a huge amount going on out there so far, it is worth saying it wasn't dissimilar at the same stage of the Sri Lanka innings.
The 25th over soon changed all that so let's see what happens...

That went very fine down the leg side.
The runs keep coming for Bangladesh as Najmul Hossain Shanto sweeps a leg-side delivery from Dhananjaya de Silva away fine for four.
Bangladesh's first century stand of the World Cup comes up with a single.
Shakib Al Hasan and Najmul Hossain Shanto have put them in complete control.
They're more than halfway to their target with eight wickets in hand and a required rate of just 4.92 an over.

It's like you've got on the motorway, put cruise control on. Not much is happening.

Seven come from Dhananjaya de Silva's first over with Shakib Al Hasan thumping the ball to the deep mid-wicket boundary.
Bangladesh are finding the boundary with great regularity now. Sri Lanka are in dire need of a wicket.
Ban 133-2
Thanks, Callum.
Bangladesh are in control with Najmul Hossain Shanto looking in good touch.
He gets to his half-century with the first of back-to-back boundaries off Angelo Mathews.
It's a firm pull shot to take him to the milestone from 58 balls before thumping the next ball to cow corner.
Sam Drury is here to talk you through the next stage of Bangladesh's chase. Will they stay in control?
Target 280
A better over for Sri Lanka with Bangladesh just able to take four singles off Kasun Rajitha.

The problem with Bangladesh isn't in their skill set, it's in their ears and in their minds.

The return of Madushanka has not worked either.

Sri Lanka know they need a wicket and Kusal Mendis returns to Dilshan Madushanka.
The left-armer can't provide it though and goes for two boundaries of his own.
The first Najmul Hossain Shanto, before Shakib Al Hasan pulls nicely between deep square leg and fine leg.
The required run-rate is down at 5.19. Sri Lanka need wickets.

Target 280
Batting looks really quite easy at the moment.
Najmul Hossain Shanto helps himself to back-to-back boundaries, through mid-wicket and then over mid-on.
WinViz has it 71-29 in Bangladesh's favour at the moment.

Image source, Getty ImagesCricket is a game where the umpire is really respected.
I think there has been a bit of tit for tat. But for Sri Lanka now they need to just focus.
Target 280
Marais Erasmus, the umpire who decides to change the ball, has a conversation with Shakib Al Hasan about what has happened and why.
He seems happy to accept it.
He did say at the toss that he wanted to bat second because of the dew making it difficult for the fielding side in the second innings.
Target 280
We've already got a ball change. It is only eight overs old.
There is that much dew out there in Delhi that the ball has swelled and the seam has started to come apart already.
Adrian Holdstock comes out his briefcase.
Lydia Greenway
Former England batter on BBC Test Match Special
That wasn't the most interesting shot, but it was the tactical play that made it.
Target 280
Shakib Al Hasan has had a quiet tournament so far. Maybe he needed the Angelo Mathews dismissal from the first innings to get him going.
It certainly looks like it anyway.
He sweeps for four before driving through point for another boundary. He's up to 28 off 29 balls.
