Worcestershire have shown plenty of spirit since tea and achieve their second reward as Tom Westley edges to keeper Ben Cox, who breaks the stumps for a potential stumping just in case the catch isn't given.

Sussex v Warwks 264-2

Glamorgan 186 v Kent 32-1
Promotion-chasing Kent lose their first wicket at Canterbury as Timm van der Gugten produces a delivery which bounces a little more than Sean Dickson expected and he can only edge to first slip.
The new batsman is Joe Denly, who is being talked about in terms of a place in England's squad for Sri Lanka. Based on recent newspaper quotes, head coach Trevor Bayliss knows who he is - so that's a good start.
Worcestershire 94 v Essex 165-3
Image source, Rex FeaturesSince making 96 and 178 not out in a second XI game last month, Tom Westley has been back to something like his old self for Essex.

Yorks 160-9 v Hants
The end is nigh for the Yorkshire innings as Steven Patterson becomes the sixth batsman to be castled.

Sussex v Warwks 258-2
Jofra Archer takes the new ball at the other end and bowls a maiden.
Good ball from Robinson who really hits the deck and gets one to seam and bounce away from Trott sharply.
He loses the radar a bit with the next ball and Trott tucks him round the corner for four.
Trott is beaten twice more off successive balls from Robinson and the batsman is staring ruefully at the pitch.
Surrey 305-3 v Somerset
Two runs off Tom Abell and there is a 74-ball half-century for Dean Elgar, the fourth Surrey batsman to reach 50 in the innings - but will he be the first to convert it into a ton?
The new ball is only five overs away and Somerset need to make good use of it if they are to deny the new champions maximum batting points.
Yorks 155-8 v Hants
Jack Brooks gets a couple of runs off Fidel Edwards and the bowler responds with a quicker ball that goes straight through him, but the stumps are intact.
Edwards pushes the ball out wider and Brooks slashes the ball through the covers for two more.
Surrey 300-3 v Somerset

Sussex v Warwks 254-2
We've just had a drinks break at Hove and Ollie Robinson takes the new ball after one loosener. Can Sussex strike now?
This partnership is worth 150.
Trott gets right behind the line and plays watchfully to mid on.
The next ball seams away and beats Trott outside off stump.
Another play and miss but Trott survives the over.
That's about the only time he's looked in trouble in this innings.
Glamorgan 186 v Kent 19-0
Kent opener Zak Crawley is certainly in a hurry at Canterbury. He's made 18 off nine balls so far with four boundaries, including three in the same over from Michael Hogan. Sean Dickson has a sedate two not out from 10 at the other end.
Yorks 149-8 v Hants
Edwards is testing Bresnan with the short ball here - with two men out on the hook and two slips.
There's the double bluff!
Fidel Edwards fires in a yorker and Tim Bresnan can't dig it out.
Jack Brooks is the Yorkshire number ten.
Away from Hove and Canterbury, here's the latest in Division Two:
Northamptonshire continue to be frustrated by bad light after reducing Gloucestershire to 91-8 this afternoon.
Craig Miles (17) and David Payne (4) will return to the crease when the light improves. Brett Hutton has 4-47 to date.
Middlesex have lost a third wicket against Derbyshire with Dawid Malan caught by Luis Reece off the bowling of Hardus Viljoen for 16.
Sam Robson is still there on 120 not out and Max Holden has an unbeaten 38 as the home side have reached 249-3.
Durham have taken their 6th Leicestershire wicket, with the hosts struggling on 227-6 after a promising stand of 77 between Harry Dearden and Neil Dexter.
Harry Dearden was the last man out, caught behind off the bowling of Mark Wood for 32. Neil Dexter was dislodged one over beforehand, lbw to Gareth Harte for 43.
Surrey 285-3 v Somerset
No major alarms for Surrey in the early overs after tea at Taunton. Dean Elgar is 36 not out and England's Ollie Pope has just reached double figures with an extravagant cut shot for four off Jamie Overton. Could those two be team-mates in Sri Lanka next month?

Sussex v Warwks 244-2
Luke Wells is operating from the Sea End as Sussex look to keep it tight before the second new ball.
Trott cuts him away to point for a comfortable single.
Bell is well forward in defense.
A rare loose ball from Wells is pulled through mid wicket for four and Bell keeps the strike with a single off the 6th ball on the leg side.
Glamorgan 186 v Kent
Kent claim their third bowling point as Joe Denly twirls one up, Timm van der Gugten pushes forward, gets an edge, and Sean Dickson manages to cling onto the catch despite moving slightly too far right and having to snatch it low to his left.
The Glamorgan innings comes to an end in the next over as Jack Murphy, having batted for over four and a quarter hours for his 80, smashes Matt Henry back over his head and is taken by Heino Kuhn at long-off.
Henry now has 70 wickets this season at a cost of just 14.75 runs each.
First job done for Kent, who will now look to build a sizeable lead. Promotion could be theirs this week.
Yorks 136-7 v Hants
Waite looks to be in the mood as he crunches Edwards off the back foot through the covers for four - and he's gone!
An entertaining cameo from Matthew Waite is ended by Fidel Edwards, who has him caught behind off a loose defensive prod.

Middlesex and England seamer Steven Finn says a benign tumour caused "complications" in his recovery from a knee injury.
