Part one is complete for Northants - they've skittled Leicestershire for 128.
Ben Raine is the last man to go to give Ben Sanderson his five-wicket haul.
A quick 400 from Northants' batsmen will have Worcetershire and Notts looking over their shoulders.
Just a reminder if you keep seeing the word 'I' or 'me'...
Gary Smee is covering Somerset against Middlesex and Worcestershire v Durham and Leicestershire v Northants.
Kalika Mehta is keeping a close on on Warwickshire versus Hampshire and Sussex v Notts.
All five matches have been pretty epic so far. More of the same please.
Leicestershire 124-9 v Northants
This is more bad news for Notts.
Northants claim maximum bowling bonus points as Richard Gleeson picks up his fifth wicket.
Dieter Klein is snaffled by Luke Procter. If Northants win with 24 points, Notts will definitely need 12 to go up.
Unless Worcestershire capitulate! My brain hurts.
Sussex 415-6 v Nottinghamshire

Notts need a maximum of 12 points to seal promotion - it seemed nailed on just a few weeks ago. Not so much now.
Leicestershire 123-8 v Northants

The 26-year-old goes to his half-century off just 48 balls.
Great counter attack by the Leicestershire number 8.
Sussex 421-7 v Nottinghamshire
Michael Burgess' brilliant innings come to an end as he is bowled by Harry Gurney for a first-class best of 146.

Somerset 236 & 7-0 v Middlesex 142
Gorgeous from Ed Byrom.
The 20-year-old opener punches Tim Murtagh through mid-off and to the rope.
Middlesex's body language doesn't look great at the moment. They know they're in trouble.
Worcestershire 220-6 v Durham
Ravichandran Ashwin is a mightily fine cricketer.
The India all-rounder makes his first half-century for Worcestershire to put them in a good position against Durham.

Somerset 236 & 0-0 v Middlesex 142
Ed Byrom and Marcus Trescothick are already in the middle for Somerset.
Tim Murtagh has the new ball in his hand. Middlesex need something special from their bowling unit.

Image source, Rex FeaturesEssex 227 v Yorkshire 93-6
A few people have been asking if we've forgotten about Essex today.
With Essex already champions and Yorkshire safe, the focus has been on the games where relegation and promotion can be decided.
What I can tell you is that Yorkshire are 93-6 at Chelmsford, still trailing by 134.
Neil Wagner has starred with the ball, taking 3-21.
Somerset beat them and Hampshire take seven points at Edgbaston.
If Hampshire bowl out Warwickshire inside 110 overs and then score 350 plus in their first innings, they will be safe.

There's some breaking news from the England camp this lunchtime.
All-rounder was arrested after an incident in Bristol following victory over the West Indies in the third one-day international.
He will not be available for England's fourth one-day international against West Indies on Wednesday, the England and Wales Cricket Board has announced.
Team-mate Alex Hales, who was with Stokes, will also miss the match and has returned to Bristol to help police with their inquiries.
Warwickshire 79-5 v Hampshire - lunch
Kevan James
Sport Presenter, BBC Radio Solent
Dominic Sibley has stood tall in this session and played quite superbly. He looks strong and has played some crisp drives. He's led the recovery from 12-4.
Interesting how batting doesn't look quite so difficult now as from the first 45 minutes.
As the sun continues to shine this pitch looks as though it's going to be a good one.
I understand Kyle Abbott, who had to leave the pitch after bowling just 9 balls (2 wkts and no runs) due to an ankle injury, will return after the break.
Somerset 236 v Middlesex 128-9
Four balls after lunch Craig Overton sends James Harris' middle stump cartwheeling out of the ground.
Great start for the hosts, not such a good one for the visitors after the break.
Ravi Patel is the last man in.
Sussex 389-6 v Nottinghamshire
Adrian Harms
Sports reporter, BBC Sussex
Sussex have reserved their best batting performance of the season for the last game, scoring 159 runs for the loss of Delray Rawlins on a scintillating morning at Hove.
Michael Burgess (134 not out) and Chris Jordan (81 not out) have added an unbeaten 157 with Burgess reaching a maiden first class century and Jordan his best score of the season in an exhibition that has had the Hove crowd on their feet.
Notts will want to pick up a third bowling point in the remaining 11 overs, but will also be anxiously watching developments at Grace Road.

Alex Johnson: Middlesex always seem to be in a battle at the end of the season be it for the championship or for relegation
That's why we love the county game Alex. Always unpredictable!
Regarding the post at 12:24 about 'what if Hampshire and Middlesex finish level on points' - I misread the rulebook slightly...
It would go down to who took the most points from their two meetings - not the results, which were both draws.
Middlesex (19 pts) took one more point than Hampshire (18 pts) from the two games and so they would stay up.
It's an unlikely scenario - Hampshire would need to make 300-350 in their first innings and still lose the match at Edgbaston - all after day one was washed out!
Kent 302 v Glamorgan 101-5 - lunch
Nick Webb
BBC Wales Sport
Kent's seamers have had a raw Glamorgan side under the cosh in the first session with the ball moving around in cloudy conditions.
153 is the follow-on target for the visitors, and they're still 52 short despite Chris Cooke and Andrew Salter steadying the ship for the 45 minutes before lunch.
Earlier Connor Brown survived an hour before falling lbw to Darren Stevens for 2, while Jack Murphy on 22 steered Adam Milne to point.
Callum Haggett had the returning David Lloyd caught behind for 14 with his first delivery and induced Kiran Carlson to play on for 9 in a tight first spell.
