Ali c Clark b Lamb 9 (Warks 436-9 v Sussex 528)
Taz Ali dangles the bat at a wide one from Danny Lamb and Tom Clark dives away to his right and clings to a very good catch at first slip.
Maximum bowling points for Sussex.
Warwickshire have lost three wickets for nine runs.

Kai Smith entertained us but he's perished going for one attacking shot too many, he's gone for 27.
Gubbins lbw 5 (Hants 54-2 - target 148)
Hello - is this about to get interesting?
Nick Gubbins tries to turn Jack White away towards square leg, but is slightly late on the shot and umpire says that's hitting.
Gubbins doesn't seem convinced but it makes no difference. His fate is well and truly sealed.
Notts 513-8 v Durham 378
Brilliant fielding on the boundary from Graham Clark keeps Lyndon James down to a single.
But there’s no stopping that as Josh Tongue steps down the wicket to George Drissell and smashes it through point for four.
He nudges a single off the next ball which takes him to 46 and that’s his highest first-class score.

Ed Barnard might have been thinking about his tea. He will be annoyed with himself, he'll feel there was 100 there for the taking.
It was a very stylish innings from him.
Hants 53-1 - target 148
That is too short and straight from Jack White and Nick Gubbins puts it away through mid-wicket for four.
Easy runs for Hampshire as their total passes 50.
Warks 428-8 v Sussex 528
Twenty-two runs needed for Warwickshire to get maximum batting points, one more wicket for Sussex to pick up the max for bowling.
Four overs in which to do either...or both!
Lloyd c O Price b T Price 7 (Derbys 19-1 - target 91)
No reason for alarm but Derbyshire lose their first wicket as David Lloyd falls victims to the Prices tandem, edging into the slips.
Harry Came is in at three for the home side - 72 more needed.
Smith c Robinson b Carson 27 (Warks 427-8 v Sussex 528)
Kai Smith goes for one adventurous shot too many and perishes in the deep.
A third wicket for Jack Carson but Ollie Robinson may have hurt himself taking the catch and goes off - not good!
Somerset 670-7 dec v Worcs 154 & 166-4
Adam Hose gets down on one knee and pulls Archie Vaughan all the way over the rope for the first Pears six of the match.
A single takes him to 39.
We have spin at both ends now, and next over Brett D'Oliveira pushes a single off Jack Leach to bring up the 50 partnership, off 67 balls.

If Somerset can break this partnership they'll be through to the Worcestershire all-rounders, with Matthew Waite next in.
Jack Leach is so persistent, he's just putting the ball in the right areas time after time and sooner or later either the ball is going to misbehave or the batsman is going to make a mistake.
He's not the best spin bowler in the world on a flat pitch but on a pitch that's giving him any reasonable measure of assistance, he can be deadly.
Essex 582-6d v Surrey 272-7
Matthew Fisher edges between wicketkeeper Michael Pepper and Jordan Cox at slip and it races away for four precious Surrey runs.
Barnard LBW b Lamb 82 (Warks 427-7 v Sussex 528)
That might have kept a bit low on Ed Barnard but he has to go.
Michael Booth is the next man in.
Stoneman b Bess 11 (Hants 47-1 - target 148)
The brain does funny things sometimes.
Absolutely no reason for Mark Stoneman to try and hit Dom Bess over mid-wicket, the ball turns just a little, he makes no contact and is bowled.
Hampshire need another 101 as Nick Gubbins joins Fletcha Middleton.
Hants 45-0 - target 148
Yorkshire spill a second chance as Fletcha Middleton edges Jack White to first slip.
"That was regulation," says BBC Radio Solent commentator Kevan James.
Spinner Dom Bess will bowl the next over.
Warks 425-5 v Sussex 528
A 50 partnership between Ed Barnard and the very exciting looking Kai Smith who has 26 from 29 balls.
Notts 504-8 v Durham 378
More frustration for Ben Raine as he swings one down the legside and again beyond the gloves of the diving Ollie Robinson.
Four leg byes and that brings up 500 and a appreciative ripple of applause from the home faithful.
Derbys 2-0 - target 91
A single each for David Lloyd and Caleb Jewell as Derbyshire begin their run-chase.
If the latter approaches this innings like he did his first, this could be over in very short order.
Somerset 670-7 dec v Worcs 154 & 155-4
Archie Vaughan drops short and Brett D'Oliveira looks to whip it square for four, but picks out the man in the deep.
He punches his bat in frustration as he jogs through for a single.
A better ball next up but Adam Hose cuts it for four to bring up the Worcestershire 150.
Hose punches the next through extra cover for back-to-back boundaries to take the Pears past their first innings total.
Hants 44-0 - target 148
Two boundaries in the latest George Hill over for Fletcha Middleton - the second thumped powerfully though the covers.
Middleton is 26 not out, while partner Mark Stoneman has nine - and is beaten by a beauty from Jack White at the beginning of the next.
White is convinced he has Stoneman lbw with his third ball, but it may have been a fraction too high.
