Gloucs v Warwks 249-7
Brookes plays out a maiden over, bowled by Zafar.
Ajeet Singh-Dale bowls to Dom Sibley on 98 and he leaves outside the off stump.
An awkward bumper strikes the glove and Sibley gets away for a single as the ball lands safely.
That's the closest he's been to getting out since he gloved a ball just short of sub fielder Dom Goodman at point when he was on 14.
He now has 99 from 234 balls.
It's not a sprint. It's a marathon.
Hampshire 38-4 v Kent 165
James Vince trudges off for a three-ball duck.

Essex 107 v Lancs 131
Essex are bundled out for 107. Jamie Porter can only fend a short delivery to Tom Hartley in the slips, and Tom Bailey has five-fer.
Still time for more wickets this evening...
Dan: "Smart batting here from Essex. Get Lancs in for a tricky half hour before the close... #bbccricket, external"
Hampshire 28-3 v Kent 165
Wickets aplenty at the Ageas Bowl too. It's a gorgeous delivery from Harry Podmore, angling it across the left-handed Nick Gubbins, who feathers one through to Ollie Robinson.
Gloucs v Warwks 246-7
Zafar is getting the ball to turn sharply from outside off stump but Brookes is able to leave the last ball of the over safely.

Simon Harmer shuffles onto off stump, and is adjudged LBW. Tom Bailey now has figures of 4-34.
Somerset 248-3 v Northants
Tom Abell is one of those batters - like former team-mate James Hildreth - who you feel really does deserve some sort of international recognition.
Three runs off Ben Sanderson carries him to his fourth Championship hundred of the season off 164 balls - and he has also now passed 900 runs for the season.

Breakthrough!

An end has opened up for the visitors.
Matthew Waite, newly signed from Yorkshire, joins Roderick in the middle.
Gloucs v Warwks 246-7
Seven overs into the new ball and Zafar Gohar is into the attack.
Gone! Briggs is forward to defend the last ball of the over and the Warwickshire number eight edges to a wide first slip.
A crucial counter-attacking innings is over.
The new batter is Henry Brookes.
Essex 105-8 v Lancs 131
Shane Snater clearly isn't aware he's batting on a minefield.
A Kevin Pietersen-esque shot with one leg up in the air flies to the midwicket fence.
He's brought back down to earth by the spin of Tom Hartley, who pins Snater bang in front of the stumps.
Hampshire 13-2 v Kent 165
Joe Weatherley chops on - a nothing shot really outside off.
Hampshire are in a bit of bother on the south coast, as Nick Gubbins joins Ian Holland.
Worcs 267-5 v Notts
No wickets yet for Notts, armed with a second new ball.
But the scoring rate has certainly slowed down.

Surrey 292-6 v Yorkshire
Jordan Clark hit a boundary off George Hill in the previous over but the umpires aren't satisfied with the light and off they go.

Clark is 55 not out and Jamie Overton has nine.
Gloucs v Warwks 244-6
Payne drifts into the pads and a Briggs clip pushes the ball rapidly through square wicket for four runs.
