Glamorgan 424 v Northants 185 & 304
Northants are all out and Glamorgan have a total of 66 to chase.
They will have a short break at Sophia Gardens and Glamorgan will have about 14 overs left in the day.
Durham 664 v Notts 407 & 33-0 - trail by 253
Brydon Carse steams in for his second over and so nearly makes the breakthrough.
He finds the inside edge of Ben Slater's bat and it misses the timbers by a whisker. Down to the fine leg boundary for four.
A wide and no-ball from an eight-ball over.
Somerset 102-4 - target 150
Image source, Getty ImagesLewis Gregory gets a thick edge on it from Nathan McAndrew and it runs down for four.
That takes Somerset past 100 and they're two thirds of the way there to the target now.
Lancs 458 & 116-3 v Derbys 314
Lancashire are picking up the momentum as they look for quick runs and set up a declaration,
No easy feat on a pitch not easy to play your attacking shots.
Luke Wells looks to smack Jack Morley back over his head but doesn't time it and settles for a single. He moves within six of reaching fifty for the second time in the match.
Matty Hurst goes across the stumps and flicks the ball down to fine leg for four. He moves to 30.
The lead climbs to 260. Eight overs remain today.
Somerset 98-4 - target 150
Anthony Gibson
BBC Radio Somerset
He'd been batting really nicely but pushed with firm hands, it took the outside edge and carried.
He will be bitterly disappointed not to see his team over the line.
Sussex have given a good account of themselves.
Abell c Haines b Coles 27 (Somerset 98-4 - target 150)
Commentator's curse strikes again. Sorry, Tom Abell...
James Coles gets one to spin away from Abell on the drive and he edges it to Tom Haines in the slips, who takes the catch for Sussex.
Nine overs minimum of the day remaining. Somerset need 52 to win, Sussex need six wickets. It's not over just yet.
Somerset 98-3 - target 150
Tom Abell took a fair while to get going in this run chase for Somerset but he's going along nicely now, moving onto 27 from 59 balls.
This has been a vital partnership between Abell and Lewis Gregory for the hosts to stem the flow from Sussex following their three early wickets.
The partnership is now worth 68 runs.
Warwicks 194 & 220 v Hants 300 & 203
Richard Wilford
BBC Radio WM commentator
A really competitive game of cricket.
Kyle Abbott was the major difference, Hampshire did get the better bowling conditions overall.
After getting humbled at Notts, Hampshire responded really well.
Surrey 512 v Yorkshire 255 & 163-3 - trail by 94 runs
Well batted indeed, Jonny Bairstow. He nudges one into the covers for an easy single to claim his second 50 of the match.
The ex-England man has taken just 39 balls to get there. More of the same needed for Yorkshire.
Hannon-Dalby b Turner 8 (Warwicks 194 & 220 v Hants 300 & 203)
Lovely stroke from Olly Hannon-Dalby as he pulls John Turner to the square leg boundary for four, bisecting the fielders.
But then he's gone and it's all over!
OHD plays down the wrong line and Turner rocks back the off stump to seal an 89-run win.
Their first win since the opening round of the season and a first defeat of the campaign for the Bears.
Surrey 512 v Yorkshire 255 & 162-3 - trail by 95 runs
And just like that, Surrey's lead over Yorkshire is now below 100.
James Wharton edges one down to third man for four from Nathan Smith.
These two have put on 79 together already. Remarkable stand in just 12 overs.
Surrey 512 v Yorkshire 255 & 158-3 - trail by 99 runs
Jonny Bairstow flies onto 49 from 38 balls as he unconventionally hooks one for four down towards long leg before playing a similar shot to smash Matt Fisher into the stands for six.
Next ball? Bairstow plays the same shot AGAIN to send it over the rope for two maximums on the bounce.
Warwicks 216-9 - target 310
Just what you want to see as a tail-ender - Kyle Abbott is brought back into the attack.
Tazeem Ali (11) negotiates the six balls. Maiden.
Surrey 512 v Yorkshire 255 & 142-3 - trail by 115 runs
James Wharton plays a lovely shot down the ground off Matt Fisher and he picks up another three to move onto 61.
Yorkshire have done well to dig in and frustrate Surrey this evening.
They'll hope to keep plodding along and eventually put themselves in a position to get a result from this match.
Surrey need a wicket or two to start making some in-roads if they want to win this.
Warwicks 216-9 - target 310
Tazeem Ali edges Brad Wheal but it's wide of first slip and brings Warwickshire within 100 of the target.
Unfortunately for home hopes, it's the last pair at the wicket.
A single brings the deficit down to 97.
Olly Hannon-Dalby gets the faintest touch to a legside ball which beats the diving Ben Brown and runs for four.
Somerset 81-3 - target 150
A captain's performance so far from Lewis Gregory in this run chase for Somerset as he brings up his 50 with a couple through the leg side.
His fourth half-century of the campaign and what a time to do it when his team were under pressure early doors in this second innings.
Somerset 79-3 - target 150
Mark Davis
Former Somerset seamer on BBC Radio Somerset
Somerset are edging into a strong position here.
Abell is looking strong and confident now.
It's important this partnership grows.
