Lancs 200-4 - target 424

van Buuren b Sales 8 (Northants 465 v Gloucs 268 & 135-5 (f/o))
Now that's what you call an inspired bowling change!
James Sales comes in for his first bowl of the innings and strikes first ball.
It tails back in a little and Graeme van Buuren chops an underedge on to the top of middle stump.
Another big scalp for Northants.
Gloucestershire's lower order offered little this morning, but they will need to find 60 more to avoid an innings defeat.
Yorkshire 469 & 150-5 v Warwickshire 263
Yorkshire take seven off a Beau Webster over to take their lead beyond 350.
They'll probably want a lead of 400 plus but should have time to get Warwickshire in around an hour before the close.
Leics 187 & 223-5 (f/o) Essex 401
We've had drinks and ready to resume, with Jamie Porter in for his 16th over.
The pitch is showing a few signs of uneven bounce as Porter gets ne to spit up at Lewis Hill.

Notts 193 v Somerset 310 & 254-6
Nottinghamshire have put a few down today... and here's another.
A rare short ball from Brett Hutton is smashed out to the boundary by Craig Overton and it goes into the hands of a diving Lyndon James very low down in front of him but it squirms through.
It was a tough chance but it goes down as a fourth dropped catch of the day for Notts.
Lancs 196-4 - target 424
Liam Livingstone clips it very fine on the legside and it runs all the way down for four.
Livingstone the takes a single to go onto 23 from 32 balls.

They need another 229 in total.
Kellaway lbw Haines 55 (Sussex 521 v Glamorgan 155 & 207-3)
Good innings by Ben Kellaway, but it's over now as Sussex skipper Tom Haines has him leg before.
That jagged back off the pitch and Kellaway is not convinced it would have hit - but he has to go.
Colin Ingram comes in at five on a pair.
One last thing to tell you regarding the Paul Farbrace interview, he is open to staying on at Hove as a part-time director of cricket - three days a week in the summer, two a week in the winter.
Middx 339 & 167-4 v Worcs 265
Leus du Plooy makes his second half century of the match.
It's come off 106 balls and included five fours. He's put 82 on so far with Joe Cracknell and they've taken the lead to 241.
Notts 193 v Somerset 310 & 251-6
First ball with the new ball from Fergus O'Neill... crashed away to the extra cover boundary by Craig Overton.
That was pretty wide of off stump and almost asking to be hit to the rope.
Overton then clips away to square leg for three more. Seven runs from two balls with the new ball and Somerset pass 150.
The lead is 368.
Middx 339 & 165-4 v Worcs 265

Notts 193 v Somerset 310 & 244-6
Craig Overton avoids the pair for Somerset and gets off the mark with a single from the final ball of Liam Patterson-White's over.
And now, unsurprisingly, Nottinghamshire will take the new ball.
Fergus O'Neill will come into the attack to take said new ball.
Vaughan b Patterson-White 23 (Notts 193 v Somerset 310 & 243-6)
Image source, ShutterstockArchie Vaughan comes down the pitch and tries to play a forward block but Liam Patterson-White gets it to spin past the bat and hit off stump.
Vaughan goes for 23 just three balls before Notts are likely to take the new ball.
In comes Craig Overton, who has batted well this season but is looking to avoid a pair in this match.
Leics 187 & 215-5 (f/o) Essex 401
Essex will have to bat for a second time as Ben Cox takes a single off Sam Harmer to finally move Leicestershire past the visitors' first-innings total.
Unfortunately for the Foxes, they're five wickets down in their second knock.
Durham 377 v Derbyshire 118 & 237
It happens in a rush as Derbyshire lose their last three wickets for one run as Matthew Potts finishes with magnificent figures of 8-66.
Potts has Shoaib Bashir lbw for one with the first delivery of a new over and two balls later ends the game by knocking out Mohammad Abbas' off and middle stumps in opposite directions.
Harry Came is left high and dry on 105 not out, carrying his bat through Derbyshire's entire second innings, having faced 290 balls - 230 of them dots.
Durham consolidate their lead at the top of Division Two as they take 21 points, while Derbyshire earn just two.
Lancs 185-4 - target 424
We said Lancashire need to rebuild after losing two quick wickets and they're trying to here.

Another 239 needed to win for the hosts.
Notts 193 v Somerset 310 & 238-5
Thomas Rew has his foot to the floor for Somerset.
First a four off Liam Patterson-White and now a huge six, smashing it over mid-wicket.
Rew now has his highest first-class score, moving to 70*.
Sussex 521 v Glamorgan 155 & 200-2
Image source, Huw Evans Picture Agency"He's a very talented lad," says Sussex head coach Paul Farbrace as Glamorgan's Ben Kellaway goes to his 50 from 90 balls faced. "He's played very well in this innings."
A single skewed off the outside edge brings up the half-century as Glamorgan's total reaches 200 - they are still 166 in arrears.
Bancroft c Harrison b Guthrie 64 (Northants 465 v Gloucs 268 & 114-4 (f/o))
Calvin Harrison, take a bow!
A lovely delivery from Liam Guthrie (2-36) which holds its line and forces Cameron Bancroft to play.
A thick outside edge is really travelling as second slip Harrison takes a super two-handed grab. The ball was almost past him.
Big wicket that. Graeme van Buuren is in for the second time today.
Notts 193 v Somerset 310 & 226-5
Archie Vaughan edges one to the third man boundary off Dillon Pennington and it runs away for four.
And that's a 50 partnership for Vaughan and Thomas Rew. Somerset continue to tick along nicely and the lead is 343.
