Derbyshire are 143 runs ahead.
Nottinghamshire 273 & 218-7 v Warwickshire 201-9
Hang on. Two in two for Briggs. He's on a hat-trick.
That's the end of his over though, he'll have to wait six balls. Stuart Broad is the new man in.
Nottinghamshire 273 & 218-6 v Warwickshire 201-9
Another wicket falls at Trent Bridge as Nottinghamshire skipper Steve Mullaney is caught at point by Rob Yates, cutting a Danny Briggs loosener.
He falls for 42. Nottinghamshire's lead is now at 280.
Surrey 432-4 v Leicestershire 375
While Ollie Pope continues to close in on 200, his partner Jamie Smith has just brought up his half-century.
This pair have continued to score at a really decent rate, with Smith's fifty coming off 77 balls.
Surrey have also brought up maximum batting points and now lead Leicestershire by 57 runs.
Hampshire 319 & 290-4 v Middlesex 79 & 41-3
Having started really steadily and safely negotiated the first 11 overs, Middlesex have suffered a mini-collapse.
Max Holden was trapped in front by Kyle Abbott, before Mohammad Abbas took his eighth wicket in the match by dismissing Stevie Eskinazi.
The visitors, still trailing by 490, face a really tough task.
Lancashire 305 & 185-5 v Northamptonshire 177
A well-deserved 50 for Lancashire's Steven Croft comes off 99 balls with five fours.
The hosts' lead now stands at 313. Dane Villas may be thinking about declaring soon.
Essex 96 & 302-8 v Durham 259
It's 300 up for Essex in this sensational game at Chelmsford.
Number nine Ben Allison is unbeaten on 43 while number 10 Sam Cook is 21 not out.
Essex's lead is now 139 runs. Durham will want to get these last two wickets as soon as possible. Batting last on this surface won't be easy.
Kent 265-9 v Yorkshire 379 & 139-2
Root watch. England skipper Joe Root is looking steady on 16.
Adam Lyth is hunting down his first century of the season. He's on 90 not out at the other end.
Yorkshire's lead has just passed 250.
Somerset 312 & 71-6 v Gloucestershire 309
This match could be over and done with today at this rate.
Ryan Higgins is back into the attack and back among the wickets, bowling Craig Overton for two to leave Somerset seven down.
This would be a memorable win for Gloucestershire if they can see it through.
Surrey 379-4 v Leicestershire 375
Image source, Rex FeaturesOllie Pope is still flying along at The Oval, moving to 168 not out - and at a decent strike rate of 81.55.
He'll definitely be eyeing 200 from here and, possibly, even his first-class best score of 251.
He's helped his side past Leicestershire's first-innings 375.
Nottinghamshire 273 & 198-5 v Warwickshire 201-9
Olly Stone also picks up his third wicket as the England man moves to figures of 3-43 trapping youngster Lyndon James for 31.
Nottinghamshire's lead is 271. The Bears still have plenty more work to do, but Stone looks in fine form.
Glamorgan 285 & 95-4 v Sussex 481
Wicket number three in the innings and a seventh in the game for Ollie Robinson.
Andrew Balbirnie is trapped leg before by the Englishman and goes for 29.
Glamorgan still trail by 101 runs with six wickets left to save this game.
Somerset 312 & 68-5 v Gloucestershire 309
The momentum at Taunton remains very much with Gloucestershire, who have taken their first wicket after lunch.
Steven Davies, who scored 87 in the first innings, is the man to fall, caught by George Hankins off the bowling of David Payne.
Somerset's lead is just 71 with only five wickets in hand.
Lancashire 305 & 172-5 v Northamptonshire 177
Another run out, what's happening at Old Trafford?
Rob Jones is left stranded and goes for eight.
Lancashire's lead has now hit 300. Maybe they're playing for a declaration?
Kent 265-9 v Yorkshire 379 & 116-2
Image source, Rex FeaturesSlow and steady so far from Joe Root who has seven from his first 15 deliveries.
Partner Adam Lyth is onto 75 not out. Lyth of course fell for 97 in the first innings.
Lancashire 305 & 163-4 v Northamptonshire 177
Mix up and Dane Villas is run out by Tom Taylor. That's Taylor's second run out of the game having removed Alex Davies in the first innings.
Villas goes for 24. Rob Jones joins Steven Croft (43 not out) in the middle.
Hampshire 319 & 290-4 v Middlesex 79 & 30-1
One down, nine to go. Sam Robson falls for 19 as Mohammad Abbas strikes at last, bowling the former England opener.
Abbas dismissed every one of Middlesex's top six in the first innings.
Derbyshire 390 & 26-0 v Worcestershire 305
Play resumes in Derby with Luis Reece (two not out) and Leus du Plooy (15 not out) at the crease.
A reminder that opener Billy Godleman has retired hurt.
Off we go.
Slowly but surely players are returning to the field. The afternoon session in all of our games is about to get going.
