Kent 275 v Somerset
Beautiful shot!
An on-drive from Joey Evison is inches wide of the stumps, but that emphasises how straight a shot it was.

Lancs 140-2 v Surrey

An excellent innings under pressure by Joe Clarke. That's 100 runs off a 173 deliveries, a huge moment for Clarke.
Really impressive stuff, he came in when there had been a couple of quick wickets with the game certainly in the balance, if not favoured towards Essex.
You can't underestimate the importance of this partnership between Jack Haynes and Joe Clarke.
Kent 271-8 v Somerset
Poor fielding in the covers, but Matt Parkinson won't care.
It gets him four and he is now on a more than useful 24 as the partnership for the ninth wicket moves to 49 with Joey Evison.
Notts 251-4 v Essex 253
Joe Clarke sweeps and then slaps Simon Harmer for successive boundaries to bring up a fine century off 172 deliveries, the 21st of his career.
Notts are just two short of Essex's total.

A much better over from Nathan Smith, forcing Mousley to play on and just outside off.
The last ball however is full on leg stump.
Mousley pushes it through mid on for two - and that takes Warwickshire past 200 in the 50th over.
Yorks v Leics 331-8
Yorkshire must have thought they would be batting by now, but Mike and Scriven have done superbly, adding over 100 for the ninth wicket.
Warwks 198-3 v Worcs 360
Good start from Mousley, who drives the second bal of the session deftly through cover for four.
He's a bit troubled by the ball moving into him though and may have been in danger had there been a forward short leg in place.
Ed Barnard has been in sparkling form today and he's facing Matthew Waite.
He tucks his second ball since tea into deep mid wicket for an easy single.
The third ball is wide and hammered through backward point by Mousley for four.
Waite is a bit distracted by the crosswind here and pulls out of his run up a couple of times in the over. Tough start for the Pears.
Lancs 128-2 v Surrey
Image source, RexNifty footwork from Josh Bohannon, who skips down the track to lift Dan Lawrence over mid on for a mighty six.
Lawrence has bowled a long spell here, with the quicks rotating at the Brian Statham End.
Kent 263-8 v Somerset
Credit to Matt Parkinson, but he is offering excellent support to Joey Evison.
Parkinson has scored 16 and he has helped Evison put on 41 so far and get over the 250 mark.
Warwks 189-3 v Worcs 360
That 360 from the Pears is starting to look a bit light, but Warwickshire still gifted a wicket when in complete control before the break so Worcester won't be disheartened at this stage.
Ed Barnard resumes on 56 with Dan Moseley on one.
Nathan Smith will bowl to Mousley.

Jack Haynes' impressive debut for Nottinghamshire continues, as he clips Sam Cook off his pads for a four with the ball skimming away over the grass past square leg.
Kent 252-8 v Somerset
Too short from Ned Leonard and Joey Evison is onto the back foot to pull it through midwicket to the fence.
Good work from Evison, now on to 67, to get his side a batting point.
Middlesex 55-0 v Glamorgan 620-3 dec
Short and wide from James Harris - a proper loosener after tea - and Mark Stoneman laces it off the back foot for four.
That brings up the half-century stand between Stoneman and Sam Robson.
And another four. Harris goes too straight and Stoneman helps it fine.
Only 565 runs behind now!
Lancs 119-2 v Surrey

BBC Radio London commentator
I thought we'd have a bit of floodlit cricket but I'm not sure we'll need the floodlights.
The other thing is with Dan Lawrence bowling, we'll get through the overs quickly.
I think we'll get through the day naturally.
Notts 205-4 v Essex
Notts are within 50 of Essex's first dig - Clarke and Haynes are continuing to nudge and nurdle away into their sixties, having come together at 100-4.
