Essex aren't happy with the ball. Tom Westley's led the appeal to the umpires, who've agreed to find another one after the original one fails to pass convincingly through the gauge.

Interesting it's not a box of spares. It's more like a bowling bag. Looks navy and white leather. Nice.

Anyway, they've found a decent enough replacement and Shane Snater's back bowling.

Four off the over. New old ball behaving itself.

It had been a very good 35 minutes for Worcestershire until that moment but Essex badly needed that wicket.

They needed to make inroads because Worcestershire will be trying to get a first innings lead which they are very capable of meanwhile Essex they need wickets.

It's been a tidy start from Brett Hutton, he's gone for a slightly straighter channel than Josh Tongue, just looking to attack those stumps.

It looks like he's getting a little movement too as to be expected.

At last we get some play in Birmingham as Warwickshire resume and, after a tight start from Josh Tongue and Brett Hutton, we've seen the first runs of the day.

Sam Hain has just caressed the 15th delivery to the cover boundary off Tongue.

Lovely shot.

Australia all-rounder Cameron Green is out for 112 for Gloucestershire, pinned lbw by Kent seamer Nathan Gilchrist. Gilchrist now has 7-79 and the visitors are 410-9 at Canterbury.

Play has resumed at Old Trafford between Lancashire and Leicestershire. Lancashire start on 61-3.

Derbyshire batter Brooke Guest missed out on a century against Northants. He was out for 91. The game is in the balance with Derbyshire on 233-5.

Middlesex have lost their first wicket at Lord's against Glamorgan. Stephen Eskinazi was the batter to go for 39. The hosts are 75-1, trailing by 124.

The early rain has cleared, there are some blue sky overhead as well as some cloud.

I think the forecast is pretty good for the day which will come as a mixed blessing I suspect to Somerset supporters.

Somerset reeling, a very disappointing batting performance after a very good start.

Durham took little time to end the Yorkshire first innings this morning, with Ben Raine taking the first wicket of the day on his second delivery, havig taken two in two with the first over of the new ball last night.

He bowled debutant Ben Sears for one, with the bail nearly making its way off the field! Dom Bess was then the last man out for 66, caught on the mid-wicket boundary by Graham Clark off Matthew Potts.

Yorkshire lost four wickets for 12 runs in just six overs after the new ball was introduced. They ended up with two batting points and Durham took three bowling points.

The hosts will now be hoping the likes of Emilio Gay, Will Rhodes and Ollie Robinson can get some runs on the board following poor starts to the season.

Covers are off at the Utilita Bowl, the sun is shining through broken clouds and the umpires and players are in the middle as we are ready to get underway after a half hour delay.

Craig Overton is on strike for Somerset and Brad Wheal is set for the final ball of his interrupted ninth over.

It was hard graft for Surrey yesterday, it's a good pitch to bat and I thought Sussex batted very well.

I think it's going to be hard work for the bowlers in this game.

Surrey know that this is good pitch to bat on and it's a good toss for Sussex to win but I think they'll try and slow the whole thing down in terms of run scoring, of course wickets will help.

An effortless lean into Jordan Clark's delivery brings a single and a raise of the bat for Tom Haines who moves to 100 from 156 deliveries.

That is back-to-back centuries for the Sussex left-handed opener following his second-innings 141 against Somerset in round two and continues a very decent start to the season.

Essex are feeling their way into it a bit so far. Jamie Porter's trying to get to grips with Adam Hose's regular shuffle down the track and is trying to find that right length.

He's been driven a couple of times through the covers but not timed enough to reach the boundary.

Porter almost had Brett D'Oliveira earlier with one that reared sharply from a good length and almost grazed it.

Charlie Allison has just been tack-sharp at short-leg. He stopped a full-blooded leg-glance from Hose and has tried to throw down the stumps in one movement as he's gathered it.

His throw missed and Hose is grateful as his momentum had toppled him over and was short of his ground.

I think the first hour will be crucial, no question about that.

The pitch hasn't changed really, it's still very hard and very green with a little wear at either end.

I don't think it's going to flatten out and I think batting is going to remain a difficult exercise.

It's a rather odd looking scorecard for Gloucestershire at Kent.

The early wicket of Josh Shaw means Australia all-rounder Cameron Green has resumed his innings on 100 after retiring hurt yesterday.

James Bracey is in the middle with him - so we've got five and six batting with Gloucestershire eight down.

Two unbeaten batters on centuries - 371-8 - it could get messy for Kent.

Ben Sears might have got a little inside tickle on it but it's clipped the top of the bails.

Either way Sears has gone.

A bit more on Colchester-born Simon Fernandes, who's keeping for Essex today with Michael Pepper and Jordan Cox unavailable.

He's been a regular in the Essex second XI and made eight appearances in the One-Day Cup least season - so he knows his way around first-team cricket.

He's up to the stumps for Shane Snater and has made a very tidy start.

A maiden from Snater.
