Warwickshire 698-3 dec v Durham 517 & 2-1 (f-o)
Alex Lees can't believe he's just done that.
Durham's first-innings centurion lasts only two balls of his second knock. He chases a wide one from Oliver Hannon-Dalby and nicks behind to the keeper.
Just the boost that Warwickshire wanted.
Northants 552-6 dec v Middlesex 509-2
Image source, Rex FeaturesWe've seen some extraordinary scorecards in this round and Northants v Middlesex is right up there with them.
Middlesex are now just 43 behind the hosts at Wantage Road... could they push for an incredible victory tomorrow?
Max Holden (184 not out) and Leus du Plooy's (179 not out) third-wicket stand is worth 306.
Northants have used NINE bowlers.
Warwickshire 698-3 dec v Durham 517 & 0-0
As expected, Durham are asked to bat again and out come Alex Lees and Scott Borthwick to start the visitors' second innings with a deficit of 181.
Ten overs remain in the day's play at Edgbaston.
Hampshire 367 & 19-1 v Lancashire 484
Lancashire's Nathan Lyon, with 530 Test wickets for Australia, must relish bowling in situations like this.
There are a slip and a silly point in place as he starts with a maiden to Ali Orr.
Essex 530-7 dec & 109-3 v Kent 413
Have you ever experienced deja vu?
I thought I might have been watching a replay there but no, Jordan Cox just played two identical reverse sweeps in consecutive balls which rolled away to the boundary rope.
It might have hit the exact same spot on the rope - but we just don't have the technology here to be sure about that...
Notts 399 & 137-6 v Worcs 355
Worcestershire are rampant at Trent Bridge!
Josh Baker is among the wickets now, as Ben Slater prods forward and is caught at short leg by Kashif Ali for 23.
Notts' lead is 181.

That's what you live for isn't it?!
The tension and that's what we've been lacking, that bit of peril in this contest.
Notts 399 & 135-5 v Worcs 355
Ben Slater is dropped! Almost another for Nathan Smith!
Slater hits a powerful pull shot and Rob Jones almost grasps a difficult chance, but can't hold on.
It's a thrill a minute at Trent Bridge, you can't take your eyes off it.
Essex 530-7 dec & 100-3 v Kent 413
Jordan Cox helps himself to a couple of runs off Wes Agar and Essex have hit 100 runs in their second innings.
They lead Kent by 217.
Warwickshire 698-3 dec v Durham 517
Matt Potts picks out Rob Yates in the deep to fall to Dan Mousley for 44 and Durham are dismissed for 517 in one ball short of 140 overs.
Warwickshire could enforce the follow-on - they have to, really, if they want a chance of winning - and we'll have confirmation shortly if they've done so.
Hampshire 367 & 18-1 v Lancashire 484
Hampshire might be grateful for the experience of number three Nick Gubbins in this situation.
He's joined Ali Orr in the middle after Fletcha Middleton's early departure.
There are 13 overs left in the day and I suspect Nathan Lyon might be tossed the ball some time soon.

Just like that, this game has totally changed.
Notts 399 & 127-5 v Worcs 355
Nathan Smith has 4-15 from his nine overs and the momentum has swung violently in Worcestershire's favour in the space of about 15 minutes.

Glamorgan have declared and Derbyshire will need 401 to win.
Chris Cooke leaves the field at Sophia Gardens with an unbeaten 126. A magnificent knock.
Warwickshire 698-3 dec v Durham 514-9
Martin Emmerson

Ben Raine had been holding things together nicely for Durham this afternoon and looked set to reach his second century in County Championship cricket.
But when he was on 93, an attempt to paddle Rob Yates around the corner backfired as the ball hit his middle stump.
Seconds later, Yates took a cracking low catch off his own bowling to see off Callum Parkinson for a third-ball duck. He has career-best figures of 4-136.
Earlier, Raine put on 122 with Graham Clark for the seventh wicket. Clark was out for 76 when he went back into his crease and was trapped lbw by Yates.
Raine then put on 50 with Matthew Potts before departing. The follow-on target is 549.
Notts 399 & 127-5 v Worcs 355 - Notts lead by 171
Back at Trent Bridge, Nathan Smith finds the edge with his hat-trick ball...
But it's short of Jason Holder at slip.
What a passage of play.
Surrey 428 v Somerset 285 & 162-6
Another one down for Somerset.
Lewis Goldsworthy takes a big swing at a short Gus Atkinson delivery and it takes the slightest of touches on its way through to the gloves of Ben Foakes.
Goldsworthy, like Tom Lammonby before him, has failed to convert his half-century into a significantly higher score.
Somerset are in the lead but it's only 20 runs and they are six down.
We have about 10 overs remaining.
Notts 399 & 127-5 (lead by 171) v Worcs 355
WHAT IS HAPPENING AT TRENT BRIDGE?!
Nathan Smith has four wickets in seven balls and is on a hat-trick after hitting Jack Haynes' off stump with an absolute ripper.
Good luck, Lyndon James. He had his feet up in the dressing room 15 minutes ago wondering what he was having for tea tonight, now he's facing a hat-trick ball...
Notts 399 & 127-4 v Worcs 355

What an over from Nathan Smith, a triple wicket maiden!
That Worcestershire victory charge is very much in full swing.
This happened about an hour or so ago... suddenly the bowlers have come to life.
