Obviously averages do not tell us what is likely to happen in high pressure situations but the stats for Worcs' last man Ben Gibbon suggest he might be good for 21.18 runs.

The No 11 does have a 50 and a high score of 75 so, assuming he does not crumble given the intensity of the situation, could Fateh Singh and Tom Taylor get him close enough?

Those clusters of wickets are what have been damaging for Essex, it happend all the way through the first innings and even if you look back at last week in Somerset.

The one before tea and then the two after tea have really hurt Essex once again.

It is all about digging in now for Essex.

Ollie Robinson kicks off the final session with Tom Taylor on strike for Worcs.

Two leg byes as the ball spits off Taylor's pad and Tom Haines shies at the stumps from point as they go for a quick single.

No one backs up and they take the second in a far more leisurely fashion.

Another two run and a play and miss complete the set as Worcs get to within 55 of victory.

In the space of 10 minutes after tea and the final ball just before tea, it has turned very much back in Yorkshire's favour.

It is down to the lower Essex order to try and contribute their part.

Essex are under enormous pressure now as the Yorkshire bowlers scent more blood.

Two big appeals in that Dom Bess over against Simon Harmer - one for lbw and one for a catch behind. Neither convinced the umpire and Harmer survives.

Like new partner Shane Snater, he is yet to score and we have a minimum 25 overs to be bowled.

There will be no final session at Edgbaston with the game called off as a draw after rain arrived a couple of moments before tea.

The final-day plaudits go to Ben Foakes and Matthew Fisher, who shared a 10th-wicket stand of 158 after Surrey resumed on 369-9.

Fisher eventually fell for 40, leaving Foakes unbeaten on 174 - the highest score of his career, a superb innings which underlined how much bat has dominated ball in this game.

Warwickshire enforced the follow-on with a 161-run lead but only five overs were bowled in the Surrey second innings.

As we go into the last session this match is still in the balance although Sussex are slight favourites

Tom Taylor is very capable of scoring quickly and winning this game for Worcestershire but that comes with risks and this disciplined Sussex attack will feel they still have the upper hand.

Only time will tell, but either way this has a wonderful advertisement for the County Championship

That just shows you how cricket can change so quickly.

Essex have just got to soak up as much as Yorkshire have got to offer, but their tails are going to be up.

Warks 665-5 dec v Surrey 504 & 15-0

The covers are still on at Edgbaston where the umpires have made their way out to take a look.

Barring a dramatic and, in the context of the game overall, remarkable collapse by the 2022, 2023 and 2024 champions, this one seems certain to end in a draw.

But will there be any further play?

Lancashire captain Keaton Jennings has challenged each member of the side to ‘look at themselves’ after they sank to the foot of Division Two with defeat at Northamptonshire on Sunday.

The Red Rose began the third day at Wantage Road as favourites for victory, but allowed the Northants tail to set them a tricky target of 236 – and then collapsed from 116-2 to be bowled out for 165.

"I’ve got to ask questions of myself, the way we were going about bowling to the tail – are the decisions taken at that time the right ones? Obviously not, because the game judges you – it spits out at you what is deserved," Jennings told BBC Radio Lancashire.

"I think every individual in that changing-room can and should look at themselves and figure out ‘how can I improve by 10-20 per cent, if not more?’

"The disappointing thing for me is we’ve had four, five, six, seven opportunities in the game to win it and we squandered all those opportunities. It’s massively concerning and emotions aside, it’s just not good enough."

I must admit on the first day here when six wickets went down very quickly at 81-6, I wouldn't have put too much money on us being here after tea on the fourth day.

I probably wouldn't have said it at 11am this morning either.

A session extended by 15 minutes fails to bring the breakthrough Sussex skipper John Simpson was hoping for and everyone will stop for a restorative cup of tea.

Jack Carson sends down the final over which is defended stoutly bar a single on the third ball off the bat of Tom Taylor and Worcs go in still needing 59.

It is tempting to think that Sussex have this in the bag but you underestimate the power of a cuppa at your peril. Worcs will still believe and they should.

It looked as though this might be drifting towards a draw until that final ball of the afternoon session, when George Hill dismissed Michael Pepper to leave Essex five down.

Still hope for Yorkshire - and still work for Essex to do as Noah Thain joins Matt Critchley in the middle.

Dom Bess has ball in hand...

That’s a big blow for Essex to lose Pepper just before tea and that’ll give Yorkshire some confidence for the final session.

What a stand by Pepper and Critchley, though, a monumental effort to try and save this match.

Sussex 284 & 256 v Worcs 180 & 300-8 (target 361)

It would be dangerous for Sussex to think they have this game won already given they have removed Jake Libby.

Tom Taylor has plenty of form with the bat, notably in shorter formats and Fateh Singh clearly can hit it.

That said, Jack Carson induces a loose slog from the spinner which takes a top edge and falls short of a scrambling backward point.

Head coach Adi Birrell has challenged his side to “show what it means to play for Hampshire” after watching them slump to a fourth worst defeat by runs in their history.

Birrell admitted there were ‘harsh words” spoken in the dressing room Nottinghamshire inflicted a 366-run defeat on Sunday, with Hampshire bowled out for 116 in the second innings.

“There are no excuses and we need to be better than that and we have had a review with the team and spoke harshly. They know it was not good enough and we are not going to shy away from that," he said.

“We can’t just push this under the table. It has got to be a game in isolation. We’ve not had a defeat like this in a long time and it’s going to be tough to get up but we are going to do that. We have to show character and show how much it means to play for Hampshire.”

You can't hear silence, but the people here are totally absorbed by this game.

The crowd isn't massive but those who are here have had a thoroughly good day.
