Durham 132-4 (18.2 overs) v Northants
Ooh this isn't a great start to the 19th over as Faheem Ashraf bowls a no ball. The free hit.....
...goes for one run. Northants have got away with that one.

Graham Clark had to go for it really, pulling the ball to Charlie Thurston at deep square leg.
This is really good death bowling from Northants.

Durham 102-2 (14.4 overs) v Northants
A second wicket for Northants and it's almost a replay of the first!
Graeme White bowls it and Scott Steel chips the ball straight to Matt Coles at long on.
White now has figures of 2-34 from 3.4 overs, not bad at all.

Durham 92-1 (13.3 overs) v Northants
Just less than seven overs to go in the first innings of our only match on at the moment.
Scott Steel has just launched the ball over bowler Josh Cobb for the game's first six. Durham have really got to be targeting 140 as a minimum I think.
WICKET: Short c Coles b White 46published at 19:13 British Summer Time 19 July 2019
Durham 69-1 (10.5 overs) v Northants
Graeme White is mobbed by his team-mates, D'Arcy Short looked in good nick but he's out now, caught at long on.
That could be a very big wicket.

They're about to have an inspection at the Ageas Bowl, where Hampshire are playing Sussex.
But still no play at Chelmsford, Grace Road nor Headingley.

Durham 67-0 (10.2 overs) v Northants
Just the 11 fours and no sixes so far for Durham.
Surely with no wickets gone, they'll start to seriously up the run rate now.
50 up for Durhampublished at 19:01 British Summer Time 19 July 2019
Durham 50-0 (7.4 overs) v Northants
Two fours from D'Arcy Short in as many balls help bring up the Jets' 50.
And Australian Short looks set now, he's got 36 off 30 balls.

Essex Eagles v Surrey (19:00 BST)
Surrey captain Jade Dernbach is at the top of his mark and ready to bowl the first ball of the innings.
But the rain has got heavier, and umpires Jeffrey Evans and Jeremy Lloyds have a quick confab and decide to take the players off.
The covers are coming back on as well.

Durham 40-0 (7 overs) v Northants
I think Durham know they've got to accelerate now, they've hit 11 runs off the last over.
In other news, there seems to be a lot in at Chester-le-Street tonight which can only be good news.

Essex Eagles v Surrey (19:00 BST)
Image source, Getty ImagesIn the South Group, Essex Eagles already have a bit of pressure on them after losing their opening fixture at Middlesex last night.
The Eagles made 164-6 from their 20 overs, with Ryan ten Doeschate top-scoring with an unbeaten 74 from 46 balls.
However, they were then on the end of an AB de Villiers masterclass, as the South African plundered 88 not out from 43 balls and Middlesex won by seven wickets.
Surrey, visitors to Chelmsford tonight, won the inaugural Twenty20 Cup in 2003, but since then have finished runners-up twice.
The south Londoners are without talisman Jason Roy after his World Cup heroics with England, but do have squad member Tom Curran, Australia batsman Aaron Finch and South Africa spinner Imran Tahir.
Both these sides failed to qualify for the quarter-finals last season.

An even start so far - slow going, but no wickets.
