Warwickshire 188 & 186 v Hampshire 116 & 89-4 - target 259
Liam Dawson is doing his level best to protect his wicket.
He has gone 18 balls without scoring... how much longer will he go without making a run?
It doesn't really matter, survival is the key for Hampshire.

Lydia Jane: As a Durham fan (in full Kevin Keegan rant mode) I would love it LOVE IT if Warwickshire beat Hampshire ...
Warwickshire 188 & 186 v Hampshire 116 & 83-4 - target 259
James Vince and Liam Dawson are doing their level best to keep out Ryan Sidebottom and Jeetan Patel.
A draw is enough to keep them up and send Middlesex down.
Warwickshire need six wickets to pick up just their second Championship victory of the season and take Hampshire down to Division Two with them next season.

Hugo Smyly: Bye bye Bailey, Bailey bye bye. Come on Middlesex!
Somerset beat Middlesex by 231 runs
BBC London's Kevin Hand is reporting that the match's cricket liaison officer has graded the Taunton pitch as "below average" for excessive turn, but not "poor" which would have carried a points deduction.
Somerset are definitely safe.

Matt: Right Mr Vince, time to justify that plane ticket to Australia
Andy Stevenson: Hampshire can be the first team to be relegated from the same division in successive seasons
I hadn't thought of that Andy! They were given a reprieve in 2016 because of Durham's ECB sanctions and subsequent relegation.
Worcestershire 335 & 242-3 dec v Durham 208 & 48-3
There won't be a fairytale send off for Keaton Jennings. He's gone.
Ravichandran Ashwin finds the edge of the left-hander's bat and Daryl Mitchell takes the chance at slip.
Jennings is off to Lancashire next season.
Warwickshire 188 & 186 v Hampshire 116 & 72-4 - target 259
George Bailey attempts to reverse sweep Jeetan Patel but misses!
It is a favoured shot for the Australian batsman against spinners but seems a poor choice in the circumstances.
Hampshire have lost three wickets in 17 balls since lunch. I can hear the Middlesex cheers!
Warwickshire 188 & 186 v Hampshire 116 & 68-3 - target 259
James Vince is joined by captain George Bailey at the crease.
You would imagine a lot of Hampshire's chances of survival depends on this pair.
A good knock here would give Vince, and the England selectors, a much needed confidence boost ahead of the Ashes.

Jeetan Patel strikes!
The Warwickshire spinner had Tom Alsop in all sorts of trouble in the final throws before lunch and he finally gets his rewards.
Alsop edges to Jonathan Trott, who take a regulation catch in the slips.
Worcestershire 335 & 242-3 dec v Durham 208 & 47-2
They're also under way again at New Road.
Keaton Jennings, left out of the England Ashes squad, may want to make a statement to the selectors in his final innings for Durham.
The left-hander is 20 not out as Durham chase an unlikely 370 for victory.

Huge wicket!
Ryan Sidebottom, the lesser known Australian seamer, has Sean Ervine caught behind three balls after lunch.
James Vince comes to the crease with the weight of the world on him.
Warwickshire 188 & 186 v Hampshire 116 & 64-1 - target 259
195 runs needed for a Hampshire victory but Warwickshire spinner Jeetan Patel is making the ball talk.
We are in for a defining session in this match and undoubtedly the Middlesex players will be listening intently to what is happening at Edgbaston.
What a difference a year makes.
In the late September sunshine at Lord's a Toby Roland-Jones hat-trick sealed the County Championship title for Middlesex.
Today, they need Warwickshire to beat Hampshire to stay in Division One.
The players are about to make their way out after lunch at Edgbaston.

Sussex finally begin their second innings at Hove, holding an 88-run first-innings lead over Nottinghamshire.
The visitors need only draw this match to ensure they secure promotion to Division One.
67 overs to be bowled in the day but I am not sure they will get through all of those.
Here's the report of how Somerset retained their Division One status in the County Championship with a 231-run victory over Middlesex.
Middlesex are relegated from County Championship Division One, a year after winning the title, following defeat by Somerset.

Leicestershire take an early wicket as Dieter Klein takes the edge of Rob Newton's bat and Lewis Hill takes a good diving catch just in front of first slip.
Northants' slim promotion chances rest on them winning at Grace Road and Nottinghamshire to somehow slide to defeat at Hove.

David Gooding: Not sure with Somerset scoring 486 runs there was anything wrong with pitch. V.poor Middlesex
Harry Cunningham: Bet pitch verdict waits until Hants result. "Straussy" to pull strings to get verdict that keeps Middlesex up...
Allie Williams: The ECB ask counties to produce spin friendly pitches, then pick Crane over Leach and threaten to dock Somerset points
Leicestershire 128 & 270 v Northants 202 & 17-0
They're finally ready to go at Leicestershire.
Luke Procter and Rob Newton are in the middle for Northants - they need another 180 for victory.
But with Notts set to draw at Hove, a win won't be enough for promotion.
