KM: The Sri Lankan batting performance is very similar to last week with exception of Mathews. How different would everything be if he delayed his only meaningful innings so far by a week.
He's got six balls left to maintain that record.

Imran Tahir has never gone wicketless against Sri Lanka in an ODI before.
Imran Tahir continues and Thisara Perera picks up a couple with an uppish pull through mid-wicket before picking up a single down to long-off.
Just three off the over.

I think this World Cup has been played in a really nice spirit.

These two teams know each other well - they've played each other a lot in the last five years.
Three singles and a wide keep the scoreboard ticking along.
Sri Lanka need to just try and bat out the overs here and do all they can to muster a score together.

It's a beautiful day for cricket in Durham.

Morris and Pretorius have teamed up well this morning. they had a little bear hug to celebrate. They've kept the pressure on. And once again, Sri Lanka have either gone big, and got out, or they've defended, and they've gone nowhere.
Jeevan Mendis c Pretorious b Morris 18 (SL 163-7)
Jeevan Mendis' bizarre innings is over.
He was trying to catch-up and he attempts a big pull shot off Chris Morris but a top edge is well taken by Dwaine Pretorious at fine leg.
Not sure what to make of that innings.

Seb Poznansky: I distinctly remember Sri Lanka getting written off early on against England not one week ago, the pressure of chasing any total in tournament cricket should not be underestimated. Even 200 will be competitive.

There's been 23 runs from the past two overs.
Bonus runs from Sri Lanka. A wide is missed by Quinton de Kock and an aging Hashim Amla can't prevent it reaching the boundary.
A flick into the leg side then earns Thisara Perera three.
Big over for Sri Lanka with 14 coming off it. The JP Duminy experiment might be over.
Someone has flicked a switch in Jeevan Mendis.
He takes a couple of steps down the track to JP Duminy and his lofted drive just clears Faf du Plessis at mid-on and it races away to the boundary.
Nope, we still can't say it here in BBC Sport HQ.
