Joey Evison completes his fourth over ro get the afternoon session under way at Grace Road after striking before lunch.

He beats the outside edge as George Hill faces his first ball. Nice start.

Much of Yorkshire's hopes rest on the shoulders of James Wharton who resumes on 38.

A wicket on the stroke of lunch has tilted the game in favour of Sussex, Jake Lehmann falling LBW to Tom Haines, a decision he clearly didn't like swishing his bat in annoyance.

Prior to that Hampshire had made a good start having won the toss adding 54 for the first wicket against some inconsistent Sussex bowling, the exception being Jaydev Unadkat who bowled an excellent line and length without taking a wicket.

However the introduction of Tom Price who claimed the wicket of Toby Albert stemmed the flow of runs, and Hampshire were indebted to Nick Gubbins for a disciplined, unbeaten 47 at lunch

Taunton is this weekend celebrating a “Festival of Red Ball Cricket”, but a large home crowd might have been forgiven for wondering why the home team appeared to set off as if the ball was white, giving Warwickshire a head start they widened further just before the break.

Red-ball cricket broke out for a 90-minute period in which Lewis Goldsworthy set a responsible tone, with some attractive strokes added by Thomas Rew.

That recovery work was undermined by Beau Webster’s short spell before lunch, in which he persuaded Rew to pad up to a straight ball, and Archie Vaughan to jab to first slip.

Earlier, when there was cloud cover, the top order attacked the swinging ball without success. After Josh Thomas had prodded a low catch to Alex Davies, Tom Kohler-Cadmore immediately advanced to Ethan Bamber and edged a firm drive to second slip.

Bamber had already found both edges of Jordan Hermann’s bat, but Nathan Gilchrist had the South African flashing a drive to third slip in the next over, giving Warwickshire a bonus point only 20 balls into the match.

Surrey cricketers are well on top after the first session of the first day of the county championship fixture against Glamorgan at Cardiff with the hosts struggling at 71-4.

Bowling a disciplined line and length the home side found scoring difficult at Sophia Gardens which resulted in a flurry of wickets .

Billy Root in for the injured Zain ul Hassan was the first to depart as he was caught by Sam Curran off the bowling of Shaun Abbott and the Australian picked his second wicket as he clean bowled England Lions opener Asa Tribe.

Gus Atkinson, who’s hasn’t been picked by England for the 2nd test at the Oval against New Zealand due to disciplinary issues, quickly got in on the act as he took the wickets of both captain Kiran Carlson and Ben Kellaway .

Colin Ingram and Sean Dickson managed to dig in prior to lunch but a lot will depend on the pair if Glamorgan are able to post a decent first-innings total as they will resume on 71-4.

Losing the wicket of captain Tom Westley just before the lunch interval will be hugely frustrating for Essex.

He and Charlie Allison had been rebuilding and looking comfortable following the early wickets of the openers Dean Elgar and Paul Walter but the introduction of the spin of Liam Patterson-White has drawn the breakthrough.

That'll give Nottinghamshire a big boost going into the afternoon session while Essex will need to dig in.

A touching moment at Cardiff before play got underway this morning.

The National Cricket Centre at Sophia Gardens has been named after Hugh Morris.

The very-well respected former Glamorgan and England batsman and chief executive died of bowel cancer aged 62 in December.

Canterbury: Kent 69-0 v Middlesex

Worcester: Worcestershire v Gloucestershire 78-2

A strong morning for Surrey and Gus Atkinson.

The England seamer has taken two wickets. Sean Abbott has also struck twice to put Glamorgan in trouble after the hosts won the toss.

Cameron Bancroft has batted through the morning to reach 34 at lunch with Miles Hammond 26 not out to lead a recovery from 35-2.

But Worcestershire have not let them get away and the home bowlers will be reasonably satisfied with their two hours of graft.

No prizes for which team will enjoy their lunch more at Chesterfield.

Derbyshire inserted Lancashire at half 10 and have whittled out over half of the Red Rose batters with two each for Ben Aitchison and Mohammad Abbas.

Harry Singh reaches lunch not out on 26, the highest score so far, but that is a mountain of work for him and George Balderson, who has survived to make 19.

Ben Dawkins and Ben Compton do make it through unscathed to the lunch break.

Dawkins is outscoring his partner, 39-23, and while the scoring rate may not be the best, but they are doing what is required of opening batters in setting up the innings.

Plenty of food for thought for Middlesex over the next half an hour or so.

While his Test side have been struggling against New Zealand at The Oval, the England skipper Ben Stokes has had an eventful morning for Durham.

He had a catch dropped off the fourth ball of his first over, hit Luke Procter on the head with a bouncer and was pulled for six by Ricardo Vasconcelos.

Northants have enjoyed their day so far after being asked to bat with Vasconcelos (51*) and Procter (27*) playing very nicely.

The Division Two leaders need a couple of early wickets after lunch.

A decent repair job done by the Essex skipper Tom Westley (44) and Charlie Allison (13*) until the Essex skipper edged to slip just before the interval.

That was after Notts removed Dean Elgar and Paul Walter and had the home side rocking at 31-2 after they had won the toss and elected to bat first.

The defending champions have bowled with good discipline and that dismissal of Westley is a huge bonus.

Derbyshire v Lancashire 100-6

Well Lancashire are going to avoid the ignominy of being bowled out for double figures in this innings.

Brought up in a manner befitting some of the batting as George Balderson under-edges one from Ben Aitchison to fine leg for four.
