Keith Barker takes career-best 7-46 as Hampshire bowl out Notts for 155
Tom Lammonby scores 100 as Somerset follow-on against Lancashire
Yorkshire 50-3 at close, chasing target of 224 against Warwickshire
Former England captain Alastair Cook out for 165 for Essex
Hassan Azad and Lewis Hill hits centuries for Leics against Sussex
Yorkshire 108 v Warwickshire 155 & 40-4
What. A. Session.
And what a game we've got in store. Warwickshire did the hard work, removing Yorkshire's last two wickets first thing.
But with the bat, again they've struggled, collapsing to 27-4. Dom Sibley and Michael Burgess have though added some resistance before lunch, with the Bears leading by 87.
It's all a little tense in Yorkshire.
Somerset 42-4 v Lancashire 373
Another over of tight calls as Jack Blatherwick first appeals, thinking he's got Azhar Ali caught behind and then appeals for a leg before off the very next ball.
Graham Lloyd says no to both, and both times I reckon the umpire has just about got it right.
But boy, the ex-Pakistan international is only just holding on.

Things haven't quite gone according to plan for Division One leaders Notts this morning - so how confident are their fans of winning at the Ageas Bowl?

Yorkshire 108 v Warwickshire 155 & 32-4
Dom Sibley moves to 16 with just the second four of Warwickshire's innings.
The Bears' lead now jumps to 79. I wonder what they'd consider a good total to defend on this pitch? 150? 170 maybe?
Hampshire 226 v Notts 102-5
Two runs off Liam Dawson and there is an 85-ball fifty for Ben Slater.
Hampshire call up Keith Barker for another burst - but from the opposite end to where he had all his success earlier this morning.
The deficit is 124.
Hildreth c Wells b Balderson 2 (Somerset 38-4 v Lancashire 373)
Somerset's out-of-form top order is being exposed once again.
This time James Hildreth's fidgety innings comes to an end, as he edges to the slips.
George Balderson has his second after Luke Wells takes a smart catch, low to his right.
Somerset, by the way, trail by 335.
Somerset 38-3 v Lancashire 373
Another huge shout waved away by umpire Graham Lloyd.
Jack Blatherwick tricks Azhar Ali with a fuller one and is convinced he's got the former Pakistan captain.
A quick, firm "no" from the umpire.
Lamb b Patterson 0 (Yorkshire 108 Warwickshire 155 & 27-4)
Another one!
What a start for Yorkshire. Steven Patterson has his sixth wicket of the match, bowling Matthew Lamb who falls for a nine-ball duck.
In comes Michael Burgess who managed 66 in the first innings. How Warwickshire would love him to repeat his day one heroics.
The Bears lead by just 74.
Hampshire 226 v Notts 90-5
A single to Liam Patterson-White off Brad Wheal as he and Ben Slater post a valuable 50 partnership for the Division One leaders.
Spinner Liam Dawson takes up the attack from the other end and starts with a tidy over, which costs him one run.
Simon Kerrigan has bowled Graham Clark - who earlier was dropped in the slips two balls in a row - for 42 and Durham are 167-6, replying to Northamptonshire's 183 all out.
No luck yet for Glamorgan in Cardiff, where Gloucestershire are 25-0, replying to the home side's 309 all out.
Essex are now 391-5 following the loss of Alastair Cook for 165, with new batsman Adam Wheater hitting back to back fours off Will Jacks.
In Division Three, Sussex's first innings has come to an end on 359 at Leicester with Fynn Hudson-Prentice unable to resume after retiring hurt on day one. Ben Brown finished with 133 not out.
Mark Stoneman has faced 34 balls and has yet to score but Middlesex are 21-0 in their second innings against Worcestershire, just six runs in arrears.
Derbyshire have just lost another wicket with Matt Critchley caught behind off Grant Stewart for 27 and they are 72-4, in reply to Kent's 285.
Yorkshire 108 Warwickshire 155 & 26-3
No hat-trick. Matthew Lamb survives until the end of the over.
Hain c Duke b Thompson 0 (Yorkshire 108 Warwickshire 155 & 26-3)
Two in two. Jordan Thompson's on a hat-trick.
Again he finds the edge, removing Sam Hain for a king pair.
Incredibly, 23 wickets have fallen at Headingly so far and we're not even at lunch on day two.
Now for the hat-trick delivery. New man Matthew Lamb will face...
Somerset 32-3 v Lancashire 373
Tom Bailey thinks he has Lancashire's fourth, striking the front pad of new man James Hildreth who's yet to get off the mark.
Huge appeal, but nothing given. That one looked even more plumb than Tom Lammonby's wicket.
Benjamin c Lyth b Thompson 3 (Yorkshire 108 Warwickshire 155 & 26-2)
Got him!
Another Warwickshire wicket falls as Chris Benjamin edges Jordan Thompson to Adam Lyth in the slips.
Just the start Yorkshire needed.
Abell c Davies b Balderson 0 (Somerset 32-3 v Lancashire 373)
Two in as many overs for Lancashire.
Skipper Tom Abell is caught behind off the bowling of George Balderson.
Somerset are in a whole world of trouble as the clouds role over.
Cook c Tattersall b Moriarty 165 (Surrey v Essex 379-5)
Spinner Dan Moriarty angles one across Alastair Cook, who tries to cut and wicketkeeper Jonny Tattersall claims a thin edge to bring the former England skipper's innings to an end.
Cook batted for 450 minutes, faced 330 balls and hit 20 fours.

Liam Patterson-White picks up four through the covers off Brad Wheal.
Batting is now looking a little easier for Notts and Hampshire may contemplate an over or two of spin before lunch.
Rhodes b Patterson 12 (Yorkshire 108 Warwickshire 155 & 23-1)
Breakthrough for Yorkshire just as Warwickshire begin to accelerate.
Steven Patterson - who took four wickets in the first innings - is the man who does the damage, clean bowling opener Will Rhodes for 12.
Warwickshire lead by 70.
Lammonby lbw b Bailey 6 (Somerset 31-2 v Lancashire 373)
What a delivery from Tom Bailey who grabs his, and Lancashire's second.
After serving up a flurry of out-swingers, he gets one to nip back in, pinning Tom Lammonby leg before.
That's absolutely plumb. No hesitation from the umpire to give that one.
Hampshire 226 v Notts 68-5
Image source, Rex FeaturesKeith Barker takes a breather with figures of 5-19 to his credit - 4-8 from his spell this morning. Notts will be glad to see the back of him.
Ian Holland is his replacement and Ben Slater clips his opening delivery through square leg for four.
A square drive by Slater finds the boundary to end an over which costs Holland 10 runs - the Notts opener is 36 not out.
