And in the top tier, in case you've just joined us:
- Former England skipper Alastair Cook made 125 before he was run out, but his fine century helped Essex reach 303-8 at the close v Kent
- Yorkshire were all out for just 181 before Hampshire reached 14-1 in reply at the close, trailing by 167 runs.
- Warwickshire's ninth-wicket partnership of Liam Norwell and Henry Brookes dug in to help them recover to 275-8 at stumps v Surrey.
So, at the close on day one in Division Two:
- Worcestershire trail Middlesex by 157 runs with 7 wickets remaining
- Sussex lead Glamorgan by 22 runs with 5 wickets remaining
- Leicestershire trail Derbyshire by 84 runs with 6 wickets remaining
- Lancashire trail Gloucestershire by 158 runs with 8 wickets remaining
Tom Fell (18) and Josh Tongue (0) will resume together in the morning for Worcestershire, as they bid to continue cutting in to Middlesex's 157-run lead.
Leicestershire reach the close on day one trailing by 84 runs, with six wickets remaining.
It's been a day for the fielders in this East Midlands clash.
Ben Coad takes a leaf out of his skipper's book and gets the ball up there. Oliver Soames misses the ball, and is hit bang in front. The umpire raises his finger and that is stumps.
A boost for Yorkshire on what turns out to be the final ball of the day. Without a doubt it's Hampshire day though after shooting the home side out for just 181.
Fidel Edwards' 5-49 was the pick of the bowlers as they caused a White Rose collapse from 131-4.
With Liam Norwell and Henry Brookes' 89-run ninth-wicket stand still intact, Warwickshire reach stumps.
This pair have significantly frustrated Surrey this evening.
Steve Patterson has brought himself on after Duane Olivier and Ben Coad had little success and very nearly gets Yorkshire a breakthrough.
Big appeals for both lbw and caught as Joe Weatherley is hit on the pad and the ball balloons straight to first slip. The umpire is unmoved.
Just one more over to survive for Hampshire.
Yet another rain delay in Leeds, but as quickly as the players are off the field, they're back on.
One of the shortest delays in history.
Three more overs for Hampshire duo Joe Weatherley and Oliver Soames to negotiate.
Moments later, Philip Salt is caught behind and he's out for 103.
With that comes the close of play for day one at Brighton.
The hosts will resume tomorrow with a 22-run advantage, with five wickets remaining. It's been a fine day for them overall.
Not only do Sussex now have a first-innings lead over Glamorgan, with six wickets remaining, they are also celebrating Philip Salt's century.
He's on 103 from 105 balls. Quite a knock!
Liam Norwell is really fighting back hard for Warwickshire here by making his maiden 50 for the county. He has Henry Brookes alongside him on 23 and the Bears are frustrating Surrey at the end of this innings.
Liam Norwell and Henry Brookes' 68-run partnership has seen Warwickshire get to 250 at Edgbaston.
That didn't look very likely, a couple of hours ago.
If you were with us earlier, you may remember that BBC London's Mark Church received some treatement from Surrey's physios after an insect bite swelled up on his elbow.
The ice and generous attention from the county's staff were backed up by a precautionary trip to A & E.
But we're pleased to report that Churchy is OK.
BBC Hereford & Worcester
After scores of eight and nought on his return to Championship action, Callum Ferguson has cuffed, punched and stroked his way back into shape and helped Worcestershire steady the ship after the early loss of Daryl Mitchell and George Rhodes.
Ferguson has hit eight fours in his knock of 34 so far as the home side look to get to stumps without further loss.
Thumbs up to opener Tom Fell too who's blunted the new ball like a hero with nine off 55 balls.
The champions will be hoping to finish the Bears off tonight.
Hampshire openers Joe Weatherley and Oliver Soames head to the crease hoping to survive to the close. They'll be playing for a while at Headingley yet because of rain delays, unless bad light intervenes.
That has probably come in to the thinking of Hampshire skipper Sam Northeast, when he decided not to send out a nightwatchman to block up an end.
BBC Radio Kent’s Ben Watts at Chelmsford:
A day that looked like Essex’s for the majority ends fairly honours even, thanks to a late flurry of wickets for the visitors.
Kent took four wickets in the space of three runs as the hosts collapsed from 275-3 to 303-8 in the final session.
Alastair Cook made a typically faultless century before he was run out for just the third time in his first-class career by Sean Dickson.
Darren Stevens, Harry Podmore and Matt Milnes then collected wickets with the new ball - including that of Ravi Bopara for 61 - to spare Joe Denly’s blushes after his decision to opt for an uncontested toss.
Bad light has stopped play at Cheltenham, so that's stumps, and Lancashire will resume tomorrow morning on 47-2, trailing by 158 runs.
England's Keaton Jennings is 26 not out.
A total collapse from Yorkshire to 181 all out in a first innings that never really looked promising.
The last man out is Dom Bess, who is caught at gully by off the bowling of James Fuller.
Excellent from Hampshire. Fidel Edwards finishes with 5-49.
