Hill c Barnard b Suthar 30 (Yorkshire 469-9 v Warwickshire)
In the last over of the innings in which bonus points are available Warwickshire claim their third bowling point as George Hill edges an attempted pull shot to Ed Barnard at slip giving Manav Suthar his third wicket.
Number 11 Jack White wastes no time in hitting Suthar for the seventh six of Yorkshire's innings.
Notts 9-1 v Somerset 310
Ouch. This is a painful one for Freddie McCann.
It's short and fast from Alfie Ogborne and it traps McCann's bottom hand on the handle of the bat.
Those hurt. McCann removes his glove and gives his hand a shake.
Durham 333-8 v Derbyshire
Ben Raine steers Nick Potts through the covers for four, but Durham end the 110th over of their innings well short of a third batting bonus point. Derbyshire have top settle for two as well as they are unable to conjure up another breakthrough. Raine is now 41 not out.

Hopefully Ahmed has done enough to replace Bashir, he looks the natural long term spin option for England and extends the batting.
Mat, Gosport
Love the county game, and will be listening and following while supporting DofE students near Northleach. Hoping for some more fireworks from Livingstone as well!
Chris, Shipston On Stour
Lancashire may well need some fireworks, Chris!
Lancs 44-5 v Kent 178
Matt Milnes finds the glove of Ben McDermott but Chris Benjamin is standing up to the stumps for Kent and cannot react in time to make the catch.
It instead hits the edge of his wicketkeeping glove and loops to safety.
It could have got even worse for Lancashire there.
Helm c Roderick b Allison 21 (Middx 339 v Worcs)
Worcestershire finally wrap up the Middlesex innings as Tom Helm edges Ben Allison to be caught behind for 21. That's Allison's fourth wicket.
The final wicket stand added 43 useful runs with teenager Sebastian Morgan finishing 58 not out.
We'll have to wait and see how Worcestershire fare but there's been enough variable bounce during the Middlesex innings to suggest they've posted a challenging total.
Lancs 44-5 v Kent 178
We all know what that wicket for Kent means...
In comes Liam Livingstone for his first County Championship innings for Lancashire in almost five years.
They need something big from him here with five wickets gone for just 44.
Harris c Northeast b Mahmud 3 (Lancs 44-5 v Kent 178)
Bangladesh fast bowler Hasan Mahmud has his first wicket for Kent!
Marcus Harris nibbles at one outside off stump and it finds the edge of his bat.
It flies towards the slip cordon and Sam Northeast does very well to react quickly and take the catch low down.
Notts 5-1 v Somerset 310
First boundary of the Notts innings as Freddie McCann drives outside off from Alfie Ogborne.
It goes further square of the wicket than he'd planned but they all count.
Sussex 172-3 v Glamorgan 155
"Relatively sedate this morning, one or two nice shots," says BBC Radio Wales Sport's Nick Webb.
Sedate was certainly the word for Daniel Hughes' batting thus far - he has nine runs in 49 minutes this morning, but then suddenly launches into a cover drive off Tom Norton and that's four.
Snater b Davey 0 (Leics v Essex 371-9)
Shane Snater can be a dangerous lower order hitter but not today he won't be as Josh Davey angles one in from wide on the crease and knocks his off stump out of the ground.
Essex coach Chris Silverwood called for his side to back up a good day yesterday with another today but so far they have let him down losing 4-29 inside the first hour.
Yorkshire 458-8 v Warwickshire
This is going very much to plan for Yorkshire as George Hill and Hasan Ali complete a fifty stand for the ninth wicket.
It will be a test for Warwickshire once they get in to bat after chasing the ball around all morning.
Notts 1-1 v Somerset 310
Freddie McCann scampers through for a quick single for Nottinghamshire's first run of the innings off the final ball of Lewis Gregory's over.
Notts are 1-1 from one.
Hameed c Vaughan b Gregory 0 (Notts 0-1 v Somerset 310)
Image source, ShutterstockWow. What a start this is for Somerset and Nottinghamshire skipper Haseeb Hameed is gone for a four-ball duck.
Lewis Gregory lures Hameed into an off-drive and he edges it straight to Archie Vaughan at third slip.
Cat well and truly amongst the pigeons at Trent Bridge.
Lancs 30-4 v Kent 178
Big hit from Ben McDermott as he latches onto a short one from Hasan Mahmud, who is bowling his first over for Kent.
McDermott sends it high over square leg and all the way for six.
Yorkshire 455-8 v Warwickshire
George Hill scores his second boundary of the over off Keith Barker to bring up the 450.
It's the first time Yorkshire have secured five batting points this season.
They've previously passed 450 against Sussex and Surrey but not quickly enough to earn maximum bonus points.
Notts 0-0 v Somerset 310
Image source, ShutterstockFergus O'Neill's 6-72 for Nottinghamshire was his career-best bowling performance.
Now it's time for the batters to get to work for the defending champions.
Lewis Gregory has ball in hand for the first over for Somerset and Notts skipper Haseeb Hameed will face it, with his opening partner Ben Slater at the other end.
Potts c Guest b Potts 36 (Durham 322-8 v Derbyshire)
It had to be, didn't it.
Matthew Potts tries to on-drive namesake Nick and edges through to wicketkeeper Brooke Guest.
Potts put on 58 for the eighth wicket with Ben Raine, who has now been joined by Callum Parkinson.
Second-placed Surrey are going well against group leaders The Blaze - they lost Alice Monaghan for 49 but are 93-1 in the 18th over at Beckenham.
Hampshire are 112-1 after 18 against Somerset, with Maia Bouchier 45 not out, and Durham have reached 94-2 in the 19th against Essex.
Warwickshire are batting against Lancashire and Meg Austin is 47 not out out in their 75-2.
Yorkshire 442-8 v Warwickshire
Hasan Ali launches the first two balls of an Ed Barnard over down the ground for successive sixes.
Barnard ensure his former team mate can't emulate Sir Garfield Sobers by bowling the next delivery down the leg side.
