Derbyshire 261 & 333-3 dec v Middlesex 157 & 257-8 (target 442)
James Harris and Tom Helm have hung around for a while here for Middlesex despite facing the new ball.
Both have 21 not out and are doing their best to keep frustrating the hosts in their quest for this much-anticipated home win.
Surrey 211 & 407-9d v Hampshire 147 & 286-8 (95.2 overs)
The pigeons are tucking into some grass seed on the square at the Oval, with Sam Northeast and Brad Wheal having to wave a bat around to scare them off.
Strange now, with Northeast nailing shots out to the boundary riding-fielders but not running in order to keep the strike.
Gloucestershire 236 & 302-8 (95.1 overs) v Glamorgan 526-9 dec
Gloucestershire reach 300 in their second innings so their lead over Glamorgan grows to double figures.
James Bracey (90 not out) might also reach three figures if his partner Matthew Taylor hangs around long enough.
Surrey 211 & 407-9d v Hampshire 147 & 281-8 (94 overs)
Rikki Clarke goes around the wicket and bangs it into Brad Wheal, who ducks but doesn't get low enough and is struck on the helmet.
Clarke checks the batsman is OK and the physio comes on to go through the concussion protocol.
Surrey 211 & 407-9d v Hampshire 147 & 276-8 (92.5 overs)
Sam Northeast nudges a two off Amar Virdi to third man and takes a single into the legside the next ball to move to a maiden hundred for Hampshire.
It's come from 171 balls with 14 fours and is his 20th in first-class cricket - but crucially his first in Division One. England call-up anyone?

Gloucestershire are into a lead at Bristol against Glamorgan.
It's just a one-run lead mind and they've only got two second-innings wickets in hand.
But, the hosts avoid the ignominy of an innings defeat at least.
Surrey 211 & 407-9d v Hampshire 147 & 273-8 (92 overs)
Sam Northeast guides Rikki Clarke to third man for four before spooning a short one in the air in the legside. Luckily for him, everyone is on the boundary so he can run a single. He has 97.
Derbyshire 261 & 333-3 dec v Middlesex 157 & 232-8 (target 442)
Derbyshire bring South African pair Duanne Olivier and Hardus Viljoen back on to bowl to try and wrap up this game.
They take the new ball as well and Olivier is convinced he's had Tom Helm caught behind.
Big appeal, but umpire Martin Saggers isn't interested.
Surrey 211 & 407-9d v Hampshire 147 & 267-8 (89 overs)
Lovely stuff from Sam Northeast, who is in stand-and-deliver mode. He nails a short one from Jade Dernbach through the legside for four to move onto 91.
Surrey 211 & 407-9d v Hampshire 147 & 254-8 (87 overs)
With Brad Wheal at the other end now, Sam Northeast is at the point where he's turning down singles early in the over.
The Hampshire man creams a lovely on-drive for four though off Jade Dernbach and is 78 not out. The game is subsiding for the visitors, but can their new signing reach a century?

Derbyshire 261 & 333-3 dec v Middlesex 157 & 223-8 (target 442)
Derbyshire need just two more wickets now.
Toby Roland-Jones had been tucking in to Matt Critchley's bowling with three fours in quick succession.
But he falls in his attempt to strike a fourth and reach 50.
Ben Slater takes the catch in the deep for the hosts, who move ever closer to that well-deserved victory.

Derbyshire appear on course to end a long old wait for a home County Championship win if they can pick up these last three Middlesex wickets.
That will end a drought stretching back to September 2014.
What tales do you have from your cricketing lives of similar long waits for success?
Tweet via #bbccricket and we'll share them here.
Surrey 211 & 407-9d v Hampshire 147 & 245-8 (85.2 overs)
He's not hanging in there now.
Sam Curran's angle of around the wicket does the trick, nipping back in and trapping Chris Wood in front. It looked very straight and Wood has to walk.

Surrey 211 & 407-9d v Hampshire 147 & 245-7 (85 overs)
Jade Dernbach bangs one in short and it beats Chris Wood a little for pace, with the Hampshire number nine gloving it down the legside past Ben Foakes for four.
The Hampshire partnership is worth 39 runs now.
Derbyshire 261 & 333-3 dec v Middlesex 157 & 205-7 (target 442)
Wayne Madsen bowls a ball that almost goes underground to James Harris and somehow misses the stumps.
That's the kind of delivery you normally see on a village green early-season strip!
Harris survives - not that he knew much about it!
Leicestershire 422-9 dec v Sussex 438-8 dec & 120-3
Luke Wells has been application and concentration personified for Sussex today at Grace Road.
A half-century comes up for the right-hander during his marathon stay at the crease...

Surrey 211 & 407-9d v Hampshire 147 & 237-7 (83.2 overs)
Sam Curran angles one across Chris Wood, who gets a thick edge, but it flies just wide of Scott Borthwick at second slip. Close.
Surrey 211 & 407-9d v Hampshire 147 & 232-7 (82.2 overs)
Image source, Getty ImagesIt's Sam Curran and Jade Dernbach to strive for these remaining wickets. Chris Wood (16*) is doing a good job alongside Sam Northeast (70*) so far though and there's not a lot on the pitch to help them.
It may be a matter of patience for Surrey.
Derbyshire 265 & 333-3d v Middlesex 157 & 178-7 (66 overs)
Toby Roland-Jones and James Harris are determinedly blocking at Derby. They're going at 1.6 runs per over so far - not that it matters.
Surrey 211 & 407-9d v Hampshire 147 & 225-7 (80 overs)
After some nonthreatening filler overs from Scott Borthwick and, less so, Amar Virdi, Jade Dernbach will take the new ball for Surrey.
Could this wrap up the game for the hosts?
