Northeast b Balderson 10 (Lancashire v Kent 24-2)
Lancashire's pressure has paid off. It has been consistent line and length and now George Balderson has his reward.
It moves in the air a little and Sam Northeast ends up playing all around it, with Joe Moores stood up to the stumps, which trapped the Kent number three in the crease a little.
Balderson manages to clip the bail on the top of off stump and that's pretty much the perfect delivery.
Durham 109-2 v Derbys
Not as he intended - a full-toss no-ball well outside off stump from Martin Andersson, which Will Rhodes clatters through the covers for four.
Another boundary follows in the next over as David Bedingham steers Nick Potts through point to move to 25 not out.
Lancashire v Kent 23-1
We're into the 15th over at Stanley Park in Blackpool and Kent are yet to hit a boundary.
Very tight bowling by Lancashire so far and the visitors are slightly under the cosh.
Leicestershire v Essex 8-2

Sussex v Glamorgan 100-5
Chance? No.
Chris Cooke fails to get on top of a forcing back-foot shot off Henry Crocombe but the ball eludes the backward point fielder and speeds away for four runs.
Durham 100-2 v Derbys
False shot by David Bedingham - he was aiming for mid-wicket off Nick Potts but the ball skewed away off the leading edge into the covers. He trots through for a single as Durham's total reaches 100.
Elgar b Green 3 (Leics v Essex 8-2)
Ben Green strikes again!
The stand-in captain is certainly leading by example - he's now dismissed both Essex openers, coming around the wicket to send Dean Elgar's off stump flying.
Jordan Cox is back in the Essex side for a bit of red-ball match practice before he links up with England's Test squad and this situation is certainly a good challenge for him as he strides to the middle.
Nottinghamshire v Somerset 87-3
Thomas Rew's confidence is growing with every boundary here for Somerset.
It's too short outside off from Fergus O'Neill and Rew punches with power to the boundary once more.
That's Rew's fifth four, and they all seem to be coming through the offside.
Northants 145-3 v Glos
Nathan McSweeney's crunching on-drive off Matt Taylor races for four and that brings his partnership with Saif Zaib into three figures.
The Australian follows it up with another boundary to take him to 36, while Zaib has advanced to 57.
Good recovery by this Northamptonshire pair.

Greetings from Sydney where I’m following the Championship during a slightly chilly Aussie winter. Just wondering why Olly Stone isn’t turning out for Notts v Somerset today. He’s been in good form, hopefully he’s not injured?
Alastair, Sydney, Australia
Anyone at Trent Bridge able to ease Alastair's worries?
Nottinghamshire v Somerset 82-3
Easy pickings, this, for Thomas Rew.
Brett Hutton's last ball of the over is inviting outside off and Rew makes no mistake, slotting away through the covers for another four and he's moving along nicely for Somerset.
Rew is onto 25 and Hermann is 29* at the other end.
Yorkshire 132-1 v Warwickshire
After a frustrating morning Warwickshire's bowlers have looked more threatening since lunch.
Ethan Bamber in particular has beaten the bat a few times although Will Luxton has responded with consecutive boundaries.
Lancashire v Kent 21-1
It's slow going with the bat for Kent at the moment.
Sam Northeast tickles a single to backward square off George Balderson and that's just the second run in the past 15 minutes or so.
Middx 72-1 v Worcs
It's 12 years since Sam Robson played his seven Test matches but at the age of 36 he's still accumulating runs for Middlesex.
This has been a carefully measured innings and shortly after reaching 50 for the 93rd time in his career he produced one of the best shots of the day, clipping one off his toes through long-on for four.
Nottinghamshire v Somerset 76-3
Nottinghamshire are convinced they've got Jordan Hermann, but the Somerset opener and umpire are both unmoved.
Hermann attempts the straight drive from Fergus O'Neill and it flicks something on the way through to wicketkeeper Joe Clarke.
But it looks like it was bat flicking pad, rather than bat feathering ball.
Kellaway c and b Crocombe 33 (Sussex v Glamorgan 94-5)
One word - sensational!
Ben Kellaway tries to turn a ball from Henry Crocombe to leg but gets a leading edge and the Sussex paceman leaps to take a one-handed return catch in the very tips of his fingers.
The wickets ends stand of 51 between Kellaway and Sean Dickson, who has now been joined by Chris Cooke.
"That really was quite spectacular," says BBC Sussex's Adrian Harms.
Nottinghamshire v Somerset 73-3
Thomas Rew... just starting to get into the groove now?
Rew leans back and it's all wrists as he crashes a short one for four through backward point off Fergus O'Neill.
Another fine shot from Rew and a second boundary in as many overs for the Somerset number five.
Walter lbw b Green 2 (Leics v Essex 5-1)
Early breakthrough for Leicestershire!
Paul Walter gets stuck in his crease somewhat and is trapped plumb in front by Ben Green.
Green and Josh Davey have begun well for the home side, with the latter producing one delivery that swung back and almost cut Dean Elgar in half.
That wicket brings Essex skipper Tom Westley to the middle.
Yorkshire 124-1 v Warwickshire
After a good morning session for Yorkshire Sam Whiteman gets them going again, turning a Keith Barker ball neatly round his pads to the square leg boundary.
Warwickshire are still striving for wickets and have two slips and a gulley in place but Ed Barnard may be regretting his decision to put the home side in.
Nottinghamshire v Somerset 69-3
Notts opening bowler Brett Hutton finds the outside edge of Somerset opener Jordan Hermann's bat but it doesn't carry and drops well short of the slip cordon with one bounce.
