As County Champions for the last three years, we have become used to the Surrey machine grinding down the opposition.

With a 169-run lead at halfway, it felt like normal service was under way, but their hopes of pushing for victory today have been undermined by some uncharacteristically sloppy fielding.

Jordan Clark, Dan Lawrence and Ryan Patel have all dropped catches that could and should have been taken.

Clark and Lawrence shelled caught and bowled chances, which came at good heights, but Patel's drop off at a ball that looped towards him at bat-pad was a bad one.

Not quite Mike Gatting in India in 1993, but a bad drop, nonetheless.

A scrambled two ends with an slightly ignominious dive into the crease from Michael Pepper, trousers pulled half down and red undies showing – not quite the picture he had in mind for the scrapbook.

But that has been a great knock from the Essex keeper with his century coming in 113 balls.

Pepper received his county cap from captain Tom Westley today and he has marked it with a fourth first class century and a third this season.

And he has shown that given a platform, he can be a dangerous operator.

Three expansively hit boundaries from the bat of Charlie Allison off Dan Mousley but it is not entirely clear that that was in the script with Michael Pepper stranded at the non-strikers' end.

How about a quick single, let Pepper get his hundred and declare?

Ben McKinney struggled to cope with the left-arm spin of Sai Kishore and ended up throwing his wicket away in an attempt to try and take him on.

He'd tried - and failed - on numerous occasions to play forward defensive shots to Kishore, missing the spin regularly. It was a similar result each time he tried to cut him.

Then came an attempted slog-sweep from the 20-year-old opener, which also ended up in the keeper's hands.

And moments after team-mate Emilio Gay gestured to him to calm down, McKinney got himself out. He hit Kishore straight to Dan Lawrence at long-on and he took a low catch on the bouncdary to dimiss him for 24.

It ended a partnership with Gay of 73. Gay Now has 61.

His three previous 50s this year have all been turned into centuries. How Durham need more of that today!

It was only a matter of time, he couldn't cope with him.

It's silly cricket from Ben McKinney.

He was overwhelmed with the spin.

Yorkshire 161-2 v Sussex 222

James Wharton pummels Jack Carson for two big sixes to bring up Yorkshire's 150 (and 160), the first a hastily rearranged pull over square leg and the second an arrow straight drive back over the bowler's head.

First look at spin for Somerset in the seventh over.

Liam Dawson may have been chosen ahead of Jack Leach for the Old Trafford test, but despite being dropped for the fifth Test tomorrow, he is not yet back playing for Hampshire.

So England's loss is even more so Somerset's gain with Leach having all summer playing for his home county.

He overpitches to be taken for two boundaries by Freddie McCann through the covers in his first over.

Emilio Gay's played very nicely today.

Some nice shots to reach the half century mark and bring the deficit down.

Worcs v Hants 281-8

James Fuller has picked Khurram Shahzad over the square leg boundary and on to the top of the pavilion.

Fuller is not holding back and now has 37 off 28 with two fours and three sixes.

Durham are faring better than their last three Championship innings, these two having put on 65 runs now from 77 balls.

England Lions opener Ben McKinney was harshly dropped for a few games, but remember such is Durham's depth that Championship winning skipper of Warwickshire Will Rhodes can't get in this side.

He is on 21* whilst Emilio Gay just got to his half century off only 42 balls.

Spin from both ends now as Dan Lawrence joins Sai Kishore.

Gloucs v Middlesex 324-5

Kane Williamson loves a big score and he's just gone past 150 at Cheltenham College.

For someone who's made almost 10,000 Test runs at an average of 55, he might not be done yet...

It's good positive stuff from Emilio Gay.

Durham are ticking along quite nicely at the moment.

Essex 557-5 v Warwickshire

The rain that has arrived could not have come at worse time for Essex who will be keen to declare but also keen for Michael Pepper to reach his century.

It is not hard rain and hopefully they will be back soon and the wicketkeeper batsman will get the 10 needed to reach his personal landmark.
