Lancs 92 & 220-6 v Kent 261 - lead by 51
If Lancashire are still batting in the final session of play today, we might be in for quite a dramatic final day chase.
Jack Leaning is out of the attack for now and Joe Denly is called upon to bowl his leg spin from the Brian Statham End.
George Bell tries to drive through extra cover but can't find the gap.
The final ball of the over is full outside off and driven square for no run.
Maiden over.
Yorkshire 453-4 v Glamorgan 221
Jonathan Tattersall comes to the party and takes back-to-back fours off Mason Crane to move Yorkshire to their fifth batting point before lunch on day two.
Middlesex 153-2 v Leics 306
While Sam Robson has played a very Sam Robson-like innings, watchful when required and punishing when the bad ball is offered.
Leus du Plooy is happy to play the attacking role and moves to fifty for the third time this season.
He thumps a four off Rehan Ahmed to move to 48 and then almost goes next ball to a ball which got some unexpected bounce.
It's a false shot but brings three.
He saw off some excellent disciplined bowling from Leicestershire attack this morning and then accelerated to his 35th first-class half-century off 89 balls.
Derbys 246 & 11-0 v Sussex 479 - trail by 222
Derbyshire captain David Lloyd gets his first boundary with a leg side ball from Jayden Seales, scooped behind square for four.
Four more with a front foot glance through mid wicket.
Solid start for Derbyshire, who need to bat well into Day Four.
Lancs 91 & 214-6 v Kent 261 - lead by 45
Matt Parkinson is round the wicket to George Bell, who has a short leg fielder to look out for.
Bell taps the fourth ball away safely into the off side for one.
Lancs 91 & 212-6 v Kent 261 - lead by 43
Matty Hurst will keep the strike, working Matt Parkinson to square leg for one.
Hurst is back and across to Jack Leaning but can't clear the field on the on side for runs.
The last ball is turned away to the on side for one more run.
Yorkshire 435-4 v Glamorgan 221

Up goes the finger and Glamorgan were keen on that one for obvious reasons and Joe Root's superb innings comes to an end for 156, including 21 fours.
What a superb knock, showing his class, a class of a seasoned England international in the county game.
He has just played nicely all round the wicket as well as the elegance of his drives.
Derbys 246 & 2-0 v Sussex 479 - trail by 233
A mountain to climb for openers Luis Reece and David Lloyd.
Reece will take first strike, facing Ollie Robinson, who starts with a no ball.
Yorkshire 431-4 v Glamorgan 221
Glamorgan breathe a sigh of relief.
Joe Root misses a straight one from Jamie Harris which hits him on the knee roll of his front pad and an 165-ball epic stay is over.
A knock full of trademark composure and fine strokeplay which brought 21 fours.
Follow that Jonathan Tattersall.
Lancs 91 & 207-6 v Kent 261 - lead by 39
Jack Leaning is wider of the crease this time and a shorter ball is pulled away by Matty Hurst for a single.
George Bell defends into the on side.
Lancs 91 & 200-6 v Kent 261 - lead by 28

Jack Leaning sometimes has that golden touch.
And so it has proven.
Yorkshire 426-3 v Glamorgan 221
What can you say about this guy?
Joe Root plays a rare false shot and bottom edges a Jamie Harris ball which kept low.
He almost chops on but it whistles past off-stump and the dive of wicketkeeper Chris Cooke and it brings up his 150 off 158 balls.
He's made it look pretty effortlessly, in all honesty, in a way only Joe Root can.
Bring on the Test summer.
Hudson-Prentice c Madsen b Morley 34
Jack Morley does it again and he finishes with 3-117.
He's taken a fair bit of tap in this innings, but one ball after Fynn Hudson-Prentice is down the track to loft the ball straight for four.
He's caught at long off by Wayne Madsen trying to repeat the stroke.
A mammoth total nonetheless and a very handy lead of 233.
The last four Sussex wickets added 95 runs in less than 22 overs.
Lancs 91 & 200-6 v Kent 261 - lead by 31
Now then, how long can Lancashire keep Kent in the field?
Spin from both ends for Kent now, with Jack Leaning and Matt Parkinson bowling in tandem.
George Bell tucks a ball from Parkinson leg side and sprints a single to take the Red Rose county to 200 in the 55th over.
Yorkshire 421-3 v Glamorgan 221
Harry Brook is ticking after a watchful start and takes back-to-back boundaries off Thomas Bevan's spin.
It took 28 balls to see his first four. Mind you he had already smacked a couple of sixes by then.
He's up to 32 off 30.
Mason Crane then strays down leg and runs through for four byes and the Yorkshire lead is 200.
Lancs 91 & 197-6 v Kent 261 - lead by 28
Jack Leaning is in the attack and George Balderson misses out on dispatching a full toss. He remains on 48.
Out! That's a brilliant catch from Daniel Bell-Drummond at gully off a ball that may have deflected off the keeper.
Very sharp, low chance.
Crucial breakthrough for Kent and Matty Hurst is in next.
Middlesex 122-2 v Leics 306
Leus du Plooy has seen enough and frees his shoulders to Ben Green.
He steps down and swats a huge six over point.
Green almost exacts swift revenge when he finds the inside edge of du Plooy's bat, but it somehow evades both wicketkeeper and stumps. He's up to 33.
Lancs 91 & 196-5 v Kent 261 - lead by 27
George Balderson moves to 44 with a thick edge down to third man off Wes Agar.
This stand is becoming more than a little frustrating for Kent after the early dismissal of Tom Bruce this morning.
George Bell is nearly undone on 27 tryng to cut a shorter ball from Matt Parkinson but Zak Crawley can't hang on at first slip.
Sharp chance but catchable.
Yorkshire 405-3 v Glamorgan 221
Joe Root takes yet another single off Thomas Bevan and takes Yorkshire to a fourth batting point.
You'd be mightily surprised if they don't get maximum five points with the blade.
We're still nine overs shy from the new ball.
Middlesex 115-2 v Leics 306
Well, batted Sam Robson.
He takes two off Tom Scriven and goes to a well-made half-century.
That's a 47th first-class fifty for Robson and it's brought up off 107 deliveries.
It also brings up the 50 partnership between he and Leus du Plooy.
Middlesex trail by 191.
