Ryan Sidebottom replaces Olly Stone from the Pavilion End and starts with a jaffa that keeps low and scuttles just past the off stump of Sam Billings.
The next ball is clipped away to fine leg for four.
Big appeal for caught behind!
Did Billings hit that?
Not out. The umpires aren't sure it carried.
Gloucestershire are proceeding with caution towards their victory target against Derbyshire. They are 88-3, with Miles Hammond and Benny Howell together, and need another 91 to win.
Middlesex are on the verge of a three-figure lead against Durham, but they only have four wickets standing in their second innings, with the score 288-6.
Tom Taylor has four wickets for Leicestershire in Cardiff but Glamorgan's score of 153-8 means they are 380 runs ahead.

Sam Billings is off to a positive start with six runs off as many balls so far.

He shuffles across to try and pull a short ball and the ball thuds into the thigh pad.
Big appeal for lbw next ball and the umpire says not out.
Crawley is looking decidedly fidgety here but crucially for Kent he's still there.
Worcs 340 & 63-2 v Yorks 428 (trail by 25)
Shot! Moeen Ali gets a leg stump half-volley from Tim Bresnan and lifts the ball effortlessly over square leg for a maximum.
He's happy to leave Bresnan outside the off stump thereafter as the bowler tightens his line.

Hampshire 187 & 198 v Lancashire 273 & 50-2
Surely we are not going to see another hat-trick.....
Fidel Edwards has Lancashire's Alex Davies caught in the slips for 12 and then bowls debutant Brooke Guest with his next delivery, knocking the off stump back several yards.
...no, we are not. With a treble in his sights, Edwards gives away two no balls before Liam Livingstone hits him for four.
Four leg byes end a busy over and Lancashire need another 67 to win.
Somerset 463 v Nottinghamshire 133 & 155-7
Somerset are closing in on victory at Trent Bridge, where Ben Duckett pays the price for playing all around a full-length straight one from Lewis Gregory. Having been on loan from Northants for the past few weeks, Duckett will be a fully fledged Notts player next summer.
They need another 175 to avoid an innings defeat.
Warwks 380 v Kent 167 & 90-5 (trail by 123)
A viscous toe-crunching yorker at pace from Olly Stone who spears it straight through Oliver Robinson, leaving only one stump standing.
He's doing the business for the Bears after news that Keith Barker is off the field with an injury.

100 balls and seven fours.
Worcs 340 & 45-2 v Yorks 428 (trail by 43)
Agony for Jack Brooks as a nick by Moeen Ali disappears down to third man for four.
An innings lead feels a long way off here.
Surrey 67 & 165-1 v Essex 477-8 dec
Still no joy for Essex at The Oval where Jason Roy takes a single off Matt Coles to bring up a hundred partnership with Mark Stoneman.
Roy - playing only his second Championship game of the summer - is 71 not out and his left-handed partner has 68.
Surrey need another 245 to avoid an innings defeat.
Warwks 380 v Kent 167 & 76-4 (trail by 137)
Olly Stone is building up a head of steam here as he pings one outside off stump and the ball takes off on the way to the keeper.
The next ball thuds into Oliver Robinson's thigh pad and the batsman gratefully accepts a leg bye.
Crawley scrambles a single off the last ball to keep the strike.
Middlesex 121 & 277-6 v Durham 310
Martin Emmerson
BBC Newcastle
We weren't sure if Chris Rushworth would bowl today because of a stiff back. He didn't join in the bowling warm-up, but did have the ball in his hand for the second over of the day and soon had the two wickets needed to reach 400 in the Championship for Durham.
Paul Collingwood, playing in his last match before retirement, got a wicket with his third delivery yesterday and today claimed his second as Middlesex skipper Dawid Malan pulled him to mid-wicket to depart on 43.
At that point Middlesex had lost 4-11 in the morning session, but with the new ball taken it looks like we may have seen the last of Collingwood as a bowler.

The pitch is playing tricks here.
That's another ball that rises off a length.
The ball balloons off the shoulder of Tom Fell's bat and Ben Coad celebrates as Adam Lyth holds on to it above his head at second slip.
Warwks 380 v Kent 167 & 72-4 (trail by 141)
Jeetan Patel is into the attack and Zak Crawley unleashes the sweep off his 6th ball for four.
Stone continues at the other end. Oliver Robinson defends.
Hampshire 187 & 198 v Lancashire 273 & 20-0
England opener Keaton Jennings must be in a hurry to get back to the north west.
After a dot ball by Kyle Abbott, he hits five - repeat FIVE - successive fours from the opening over of Lancashire's run-chase at the Ageas Bowl. No wonder his nickname is Jet.
The Red Rose county need another 93 for victory.

Moeen Ali is in block mode for now against Ben Coad after the early loss of Daryl Mitchell.
He gets a single off the third ball and Tom Fell uses his feet well to drive through the covers for four.
Coad beats the outside edge of the bat to end the over.
Earlier on we described how Somerset's Craig Overton followed team-mate Tom Abell's lead by taking a hat-trick against Nottinghamshire at Trent Bridge 9see 10:40 entry).
There are many instances of two hat-tricks being taken in the same first-class match, including eight players who have achieved the feat individually.
The most recent of those was in November 2017, when Australia paceman Mitchell Starc took a hat-trick in each innings of New South Wales' Sheffield Shield game against Western Australia.
