Surrey 333 v Yorks 36-1
Fin Bean is living a bit of a charmed life at the Oval, but partner George Hill flicks a wayward Jordan Clark delivery fine for four as he advances to 18 not out. Overhead conditions are brighter and that is good news for the Yorkshire batters.
Essex 107 & 28-2 v Lancs 131 & 73
The big wicket for Lancashire!
It's a slice of good fortune for George Balderson - he's half-heartedly appealing for LBW, but the ball rolls back off Alastair Cook's pads and knocks off the leg bail.
Scott Borthwick has reached his seventh 50 of the season and Durham are 145-1, just 18 runs short of a first-innings lead against Sussex at the Riverside.
David Lloyd is now 267 not out with Glamorgan 480-5 against Derbyshire at Sophia Gardens.
Toby Roland-Jones has taken two wickets and Leicestershire have slumped to 53-4, replying to 297 all out by Middlesex.
Worcs 390 v Notts 0-0

At the other end Hammond is beaten outside off stump by Yadav but he gets away with a single off the next ball.
Out! Yadav tosses the ball up - Dent is squared up and trapped on the crease.
This looks like a more than handy first innings score for the Bears on a pitch that is turning.
Hampshire 57 v Kent 165 & 135-6
Ollie Robinson had raced to 19 from 14 balls, but flashes hard at Mohammad Abbas and nicks through to the safe hands of James Vince.
Somerset 349-7 v Northants
Josh Davey tries a reverse sweep. He doesn't middle it but a top edge is good enough to bring him four runs off Rob Keogh. He is nine not out and Lewis Gregory has 25.
Surrey 333 v Yorks 32-1
Time for Kemar Roach to take a breather after a six-over spell of 1-11.

Worcs 390-9 v Notts
Well, now I've seen everything.
Brett Hutton drops short and the Pears number 11 hooks it over backward square leg for six!
His previous highest score at this level is only 9!
He's got 20.
Glamorgan 461-5 v Derbys
Image source, GettyMagnificent effort by David Lloyd, who pulls a short ball from Alex Thomson for four to reach 250 off 338 balls.
It is the 35th boundary of his epic innings and he also has one six.

Gloucs 54-2 v Warwks 274
Yadav is driven pleasantly through the covers by Hammond for four to take Gloucester past 50.
A single off the fourth and Dent defends.
Essex 107 & 19-0 v Lancs 131 & 73

Earlier in the over, Bailey twice beat the outside edge.
Glamorgan 454-5 v Derbys
Nick Webb
BBC Radio Wales
Glamorgan captain David Lloyd has set two records on day two against Derbyshire despite losing two partners quickly at the other end.
Lloyd moved past the highest Glamorgan score at Sophia Gardens, previously 233 by club CEO Hugh Morris, and the highest Glamorgan score against Derbyshire, 234 by Aneurin Donald at Colwyn Bay.
Derbyshire kept things tight in the first session with Sam Conners trapping Billy Root lbw for 79 and the persevering Anuj Dal having Chris Cooke caught at mid-wicket for seven.
But they managed just one bowling point, with seamer Ben Aitchison unlikely to bowl again in the match after twisting an ankle in the very first over of the game.
Glamorgan, who picked maximum batting points, could now consider a declaration decision in the afternoon session as both teams chase second-placed Middlesex in the promotion hunt.
Somerset 334-7 v Northants
Somerset have to settle for three batting points but are now intent on pushing this total as far as possible.
Craig Overton pulls away a short ball from Rob Keogh for four but comes down the pitch to the next delivery, misses a head-up slog as the ball spins back into him and it's a comfortable stumping for Ricardo Vasconcelos.
Gloucs 45-2 v Warwks 274
Hannon-Dalby is a little wayward in his 5th over and Miles Hammond turns a leg side ball through to fine leg for four.
He picks up four more with a cover drive as the bowler pushes the ball wide of off stump.
Just a single comes from Yadav's second over and now Henry Brookes will replace Hannon-Dalby.
Worcs 377-9 v Notts
Four more for Josh Tongue off the bowling of Patterson-White.
That's 43 not out and his highest score in first class cricket.
Ben Gibbon is still there on 9 and needs one more for his own PB.
Surrey 333 v Yorks 14-1
Image source, Rex FeaturesSurrey strike in the ninth over at the Micky Stewart Oval as Kemar Roach finds the edge and Ryan Patel grabs a sharp head-high chance at third slip.
George Hill is in at three - he's just 21 years old and partner Fin Bean is 20. This will be a test of composure as well as skill.
Worcs 371-9 v Notts
Josh Tongue has 35 runs to his name and 79 runs have been added since he began his innings.
Ben Gibbon isn't faring badly himself as he pulls away a short ball from Paterson for his first boundary.
He rolls his wrists to keep another bumper down and takes an easy single.
An edge from Josh Tongue doesn't quite carry and the number nine pushes the last ball through the leg side for four. He's on 39.
