Adam Rossington (80*) and Luke Procter (34*) are quietly going about their work for Northants at Edgbaston, adding 52 runs for no wicket this morning.

Their lead over Warwickshire has grown to 142 runs and skipper Rossington is eyeing a ton that would further frustrate the Bears.

Takes him eight balls but Sir Alastair Cook is finally off the mark in Essex's second innings with a tuck off his hip from Darren Stevens.

Gloucestershire (267 & 169-4) lead Worcestershire (428-5) by 8 runs

Gloucestershire have just lost nightwatchman Joshua Shaw lbw to Josh Tongue after a handy 21, but George Hankins has reached his half-century.

It comes from a very patient 147 balls - Hankins will need to press on in the same vein if the hosts are to put any pressure on Worcestershire here.

Gloucestershire nightwatchman Joshua Shaw has played some nice stuff this morning, finding five boundaries to take them past Worcestershire's first-innings total of 428-5.

The hosts are 163-3 with George Hankins on 45 and they now need to press on to ensure the Pears have a meaningful total to chase later.

They're back on again at Trent Bridge, where four overs have been lost from two short showers.

It goes without saying that Notts need to break this Derbyshire partnership of Billy Godleman and Wayne Madsen before things get a bit uncomfortable.

Tom Pike: An England hopeful that should be mentioned is Craig Overton taken 7 in the match and bowling well

100 partnership for Derbyshirepublished at 11:26 British Summer Time 4 August 2020

Derbyshire (239 & 136-1) need 229 runs to beat Nottinghamshire (324 & 279)

They have got on at Trent Bridge and Billy Godleman and Wayne Madsen bring up the 100 partnership for Derbyshire.

Skipper Godleman moves onto 76 and the visitors need a further 229 for an unlikely win at Nottinghamshire.

But they're back off for rain - the early predictions are it's only a shower.

Another wicket for Dan Moriarty and that's a five-wicket haul for the Surrey slow left-armer on his first-class debut.

Martin Andersson falls to a leading edge caught at short extra cover.

5-48 for Moriarty to go with his first-innings 1-54.

Middlesex (347-6 dec & 212-4) lead Surrey (282) by 277 runs

Another Middlesex half-century on this final morning goes to right-hander Martin Andersson.

Middlesex's lead moving towards 300.

Somerset bag a sixth Glamorgan wicket in their unlikely chase of a mammoth 456 to win at Taunton.

Graham Wagg caught behind by Steven Davies off Jamie Overton for just a single.

Chris Cooke (76 not out) continues his rearguard at the other end.

While the Bob Willis Trophy is a first-class competition to replace the County Championship in this shortened domestic season, there are some differences in the format.

• A minimum of 90 overs in a day’s play rather than 96.
• Each county’s first innings of a match can last no longer than 120 overs
• The follow-on target increases from 150 to 200 runs.
• The new ball is available after 90 overs rather than 80 overs
• Points awarded for a draw increase from five (in the County Championship) to eight to help mitigate against the impact of weather during a shortened competition.
• All other points scoring remains the same as in the County Championship, such as 16 points for a win with a maximum of five batting and three bowling bonus points in the first 110 overs of a first innings.
• For the final, in the event of a draw, whichever team gains a first-innings lead will be determined the winner when both first innings are completed. In any other circumstance of a draw or tie, the trophy will be shared.

NORTH GROUP: Derbyshire, Durham, Lancashire, Leicestershire, Nottinghamshire, Yorkshire.

CENTRAL GROUP: Glamorgan, Gloucestershire, Northamptonshire, Somerset, Warwickshire, Worcestershire.

SOUTH GROUP: Essex, Kent, Hampshire, Middlesex, Surrey, Sussex.

Rather than two divisions as is the case in the County Championship, The Bob Willis Trophy sees the 18 counties split into three regionalised groups of six.

• Each county plays five four-day matches, meaning they will play the other teams in their group once.
• This is the first round of fixtures with the final round of group matches starting on Sunday 6 September.
• The two group winners with the most points after those five games will progress to the five-day final.

It is WET at Chester-le-Street and the umpires have called an early lunch for 12:30 BST.

That's means no play until after then so Yorkshire face a wait to try and wrap this match up.

They need 68 more runs to win after Dawid Malan (50*) and Harry Brook (22*) made good progress towards the end of day three.

Nick Browne glances a four off his legs from Matt Milnes' bowling to start Essex's pursuit of 202 for victory.

He's got Jamie Porter for company at the other end after the seamer performed the nightwatchman role for the one over Essex faced last night.

Floodlights are on at Trent Bridge but appears that play will start shortly, after a light shower brought the covers on.
