A lively morning at Edgbaston where six wickets fell in the first 70 minutes of play.

Four-wicket hauls from Beau Webster and the excellent Ethan Bamber helped dismiss Hampshire for 203, despite Toby Albert's 43 - to keep the visitors in sight.

Chasing 310 to win, the Bears lost out-of-sorts opener Rob Yates for two and New Zealand international Tom Latham to a six-ball duck - both to Kyle Abbott - and were tottering on 10-2.

But Sam Hain and skipper Alex Davies have batted the remaining overs sensibly to put on an unbroken 46 runs.

Warwickshire need 254 more for victory, Hampshire eight wickets.

A brilliant morning session for Leicestershire.

Things were ticking along nicely for Middlesex but they've been dropping like flies since Sam Robson was trapped lbw by Ben Green.

The hosts have lost four wickets for just 28 runs.

Surrey 505-9 v Yorkshire 255

It's a huge score by Surrey in this first innings and they've racked up almost double the number of runs Yorkshire managed.

A no-ball and a boundary as Matt Fisher swats one down to third man for four off Matthew Revis.

A fine 76-run stand from Jack Morley and Brooke Guest has helped Derbyshire fight back on the third morning of this match.

James Anderson went wicketless from his five-over spell to open the morning and the ball seemed to be doing little until George Balderson took two wickets in an over.

He removed Morley for a career-best 41 and Martin Andersson for a four-ball duck.

Guest (53 not out) and Anuj Dal (16 not out) need plenty more runs yet, with the deficit at 253 at lunch.

Another tough session for the Championship leaders as they continue to toil on a flat pitch.

Liam Patterson-White finally snared Emilio Gay for a well-made 104, but that was the only wicket to fall as Ollie Robinson (82 not out) moved Durham into the lead.

Graham Clark has added 24 quick runs and the hosts lead by 29.

Somerset are absolutely dominating this County Championship contest.

It was Sussex who inflicted a heavy 260-run defeat on Somerset in the reverse fixture at Hove in April, but Somerset seem keen to get their revenge.

The hosts have picked up another three valuable wickets in the morning session and Sussex's lead is just 38 as we head for lunch.

Serious work to do for the visitors if they're to set any sort of challenging target.

Jamie Porter has a third as he traps Ethan Brookes lbw for 38.

Brookes was the Pears' top scorer and they have set Essex 336 to win.

That feels like a lot on a pitch that has seen plenty of wickets fall - but you never know.

Harmer took 4-37, Porter 3-30 and Snater 3-45.

Sam Hain and Alex Davies are doing a good job of steadying the shop after those two quick wickets.

They've seen off opening bowlers Kyle Abbott and Brad Wheal - for now.

Hain turns James Fuller down to third man for his fourth boundary to go to 19 off 33 balls.

Alex Davies has picked up five boundaries in a 32-ball 26.

Ben Geddes survives Logan van Beek's hat-trick ball with a solid block.

But that's four wickets lost for just 22 runs for Middlesex and the advantage is now very much for Division Two leaders Leicestershire.

It's been a very calm and well put-together display from Brooke Guest.

He's batted nicely here, he's swept well, he would have enjoyed batting here, completely unflustered.

Lancs 458 v Derbys 186-6

Super stuff from the Derbyshire wicketkeeper.

Brooke Guest turns Luke Wells square into the legside and the ball beats the chase of the fielders to the rope. And that's fifty.

A 13th career red-ball half-century - and third of the season - and it's come in tricky circumstances.

Surrey are racking up a commanding lead. Tom Lawes picks up three fours in a row off the first three balls of Matthew Revis' over.

Lawes moves onto 28 from just 23 balls.

Very frustrating for Yorkshire.

Surrey seem determined to frustrate Yorkshire for a little longer...

Tom Lawes steps onto it beautifully from Jordan Thompson and clips it through the leg side for four.

Lawes then clubs one up in the air but it has enough to fly over Jonny Bairstow at mid-on and they can pick up another two.

The lead is now 220 for the hosts.
