Glamorgan 318 & 409-5 v Notts 285
Sam Northeast turns Luke Fletcher round the corner for one and there's his hundred. It's taken 133 balls and included two sixes and eight fours. Fine effort indeed.
Partner Billy Root, on 53, departs in the same over, top edging some sort of cross-bat swipe and it's an easy catch for keeper Joe Clarke.
Yorks 521 v Surrey 509-9
Can Surrey surpass Yorkshire's first-innings total?
Ben Foakes brings up the 500 with a top-edge six over the keeper and there are two fours by Dan Worrall off Dom Bess to follow.
Glamorgan 318 and 401-4 v Notts 285
Billy Root paddles a single from a slower ball by Luke Fletcher to reach an 83-ball half-century. Glamorgan are certainly intent on batting Notts right out of this game.
Du Plooy c Mackintosh b Rushworth 134 (Durham 296 v Derbys 283 & 284-5)
Leus du Plooy nibbles at one just outside off stump and Chris Rushworth has his 11th wicket of the game.
Du Plooy batted for 270 minutes, faced 206 balls and hit 15 fours, putting on 248 with Brooke Guest.
Following his 134 in the first innings, we reckon that's a pretty good effort for his side in this game. Derbyshire lead by 271.
Yorks 521 v Surrey 491-9
It's not over till it's over.
Ben Foakes flashes Jordan Thompson away for four at the end of his latest over and the first two balls of the next, from Dom Bess, also disappear to the boundary, courtesy of Dan Worrall.

From Simon: "Jennings now with his top score in First Class cricket. What a top knock this has been. #bbccricket, external"
Lancs 511-4 v Somerset 446
Image source, Rex FeaturesMilestones aplenty at Southport in the last few minutes.
First Lancs go past 500, before Keaton Jennings moves past his previous highest first-class score, and then brings up his 250 with a four through midwicket.
How's this for a fact. This is just the second time that Lancashire's top-three have all passed 90 in the same first-class innings.
The first was in May 1928 against Northants, when Frank Watson, Charlie Hallows and Ernest Tyldesley all made hundreds.
Leus du Plooy and Brooke Guest are still together for Derbyshire, who are 267-4, a lead of 254 over Durham.
Du Plooy has progressed to 123 and Guest is now on 110.
Sam Northeast and Billy Root have posted a century stand for Glamorgan, who lead Notts by 405 on 372-4.
Northeast is 76 not out but a declaration total must now be on the mind of skipper David Lloyd.

A tickle down to fine-leg brings four more to the Northants total, and takes Ryan Rickelton past 50.
He and Jimmy Neesham continue to impress - the lead is now 148.
Sussex 588 v Leics
Image source, Rex FeaturesAn imperious straight drive brings up Wiaan Mulder's hundred, the third of this Leics innings.
It took him 135 balls and included 19 fours.
McKerr c Tattersall b Bess 0 (Yorks 521 v Surrey 467-9)
Make that four dismissals in the innings for Jonny Tattersall as Conor McKerr tries to drive and edges to the Yorkshire keeper.
Spinner Dom Bess now has four wickets, but Dan Worrall deposits his next delivery into the crowd for six.
Lawes st Tattersall b Bess 13 (Yorks 521 v Surrey 467-8)
What a match Jonny Tattersall is having - an unbeaten 180 and now two stumpings to go with a catch in the Surrey innings.
Tom Lawes is beaten in the flight by Dom Bess and he tries to venture down the pitch and it's an easy one for Tattersall to complete the dismissal.
Hampshire 370-9 dec v Warwicks 217 & 164-6
After a quiet period, Michael Burgess rocks back and cracks Liam Dawson away through the covers for four.
The Warwickshire keeper is 41 not out and they are 11 ahead - but there are still 25 overs to negotiate before the close.
Vilas b van der Merwe 7 (Lancs 469-4 v Somerset 446)
A big hoick across the line from Dane Vilas sees him chop on and leaves his off-stump lying flat on the ground.
He'll be disappointed - if ever there was a time to cash in...
Yorks 521 v Surrey 458-7
Poor delivery from Dom Bess and Ben Foakes has plenty of time to adjust his feet before flicking it away for four.
Foakes is now 60 not out and England will be glad to see him in the runs after having to miss the recent Test against India.
Durham 296 v Derbyshire 283 & Derbyshire 251-4
Martin Emmerson
BBC Radio Newcastle
For the second Championship match in a row two batsmen have reached their centuries in the same over at the Riverside.
Today Leus Du Plooy and Brooke Guest got there in successive deliveries. It was Du Plooy's second hundred of the game and Guest's third this season.
In the match against Worcestershire a few weeks ago, Paul Coughlin and Ben Raine reached their first centuries in the same over, while in the Worcestershire innings Brett D'Oliveira and Ed Barnard did it an over apart.
Today's partnership is a record fifth-wicket stand for Derbyshire against Durham and is now 216 runs. They were 36-4 this morning, but as has happened so many times this season, Durham's bowlers have lost their way in the afternoon session.
Sussex 588 v Leics 417-4
Image source, Rex FeaturesColin Ackermann cuts Sean Hunt away for four through backward point to bring up a well-made hundred.
It's his 20th first-class hundred, and it featured 15 fours and a six.
Glamorgan 318 & 340-4 & Notts 285

BBC Sport Wales at Sophia Gardens
News of Worcestershire's win over Middlesex has gone down well at Sophia Gardens in Cardiff, where another Division Two promotion clash is in full swing.
Glamorgan, who are third in the table, have moved on to 340-4 in their second innings, a lead of 373 over leaders Nottinghamshire, with Sam Northeast on 57.
With a full day tomorrow and the best part of this evening session to come, all three results are still possible and there are bound to be more twists and turns in this promotion race.
Kent 335 v Northants 303 & 167-3
Jimmy Neesham and Ryan Rickelton are still there for Northants at Tea - the visitors lead by 135.
