Notts v Essex 50-1
A single for Tom Westley off Lyndon James takes the visitors' total to 50 at Trent Bridge.
Notts have at least seven bowling options at their disposal in this game, with leg-spinner Calvin Harrison making his first appearance of the season.
Perhaps also worth mentioning that Adam Rossington is in the Essex side after recovering from injury. He had been out since mid-April.
Middlesex v Somerset 52-2
Tom Abell and George Bartlett are bringing a bit of reassurance to the Somerset batting.
Ethan Bamber and Ryan Higgins have replaced the Middlesex opening pair as they look to make inroads into the visitors' middle order.
Worcs v Leics 56-2
No big score for Rishi Patel today as he tries to hook a short ball from Adam Finch but gets underneath it and skies a catch to keeper Gareth Roderick. He does, though advance his seasonal runs tally to 539.
Sussex v Glamorgan 41-4
The Glamorgan batting is being blown away.
Tom Haines is the fourth Sussex bowler in the wickets with his medium-pacers as he brings Zain ul-Hassan forward and gets the edge.
Oli Carter takes it standing up to the stumps and Sussex are jubilant.
The debutant lasts 46 balls on his maiden first-class knock.
Hampshire 80-1 v Northamptonshire
Fletcha Middleton has cruised along to 36 from 37 balls in 14 overs.
The 21-year-old has fallen for 48 and 49 in his last two appearances, after registering two half-centuries in the first match of the campaign.
He looks some prospect. Can he see this one through?
Notts v Essex 45-1
Notts tighten things up at Trent Bridge as Brett Hutton and Dane Paterson send down successive maidens.
The spell is broken by a single for Tom Westley, who has three from 29 balls so far, with Alastair Cook on 30 not out at the other end.
Surrey v Kent 51-2
First bowling change in the 14th over as Sean Abbott replaces Jordan Clark.
He's on the money straight away, but Tawanda Muyeye squirts a thick edge away for four through deep backward point from his second delivery, which was also a no-ball.
Muyeye punches another glorious four through the covers from the fifth ball but gets lucky trying another from the final ball, edging to the vacant fourth slip space and away for four.
14 off the over and the fifty is up for the visitors.
Sussex v Glamorgan 31-3
Nick Webb
BBC Radio Wales
England fast bowler Ollie Robinson won the Ashes rehearsal as he trapped Glamorgan’s Australia star Marnus Labuschagne lbw with the first ball he bowled to him.
Robinson produced a delivery which appeared to nip back and strike Labuschagne fairly low down, sending him on his way for a quick single he’d pinched second ball off Ari Karvelas.
Karvelas had already produced one which lifted on Eddie Byrom and caught the edge, dismissing the opener for five. Then first-change bowler Fynn Hudson-Prentice had Sam Northeast edging to slip, also for five, with Steve Smith left to enjoy his colleagues’ success on his home debut.
The absence of Glamorgan captain David Lloyd with a hamstring injury means Kiran Carlson leads them for the first time, while all-rounder Zain Ul Hassan is doing emergency duty opening the batting.
In-form Rishi Patel is 14 not out for Leicestershire, who are 47-1 after 13 overs against Worcestershire at New Road.
Incidentally, you can listen to an excellent BBC Radio Leicester interview (see below) with Patel - who has three hundreds already this season - about the work he did on his game over the winter by clicking here.
Scott Borthwick has just flicked Josh Shaw away fine for four and is 16 not out in Durham's 41-1 against Gloucestershire at Bristol.
Sussex v Glamorgan 31-3
From a Sussex point of view, Ollie Robinson has done his job in removing Glamorgan's gun batter in Marnus Labuschagne.
That is his last over as Fynn Hudson-Prentice replaces him.
And it is the right move by Cheteswar Pujara as Hudson-Prentice strikes third ball!
Sam Northeast had hit the first one for four, but is then brought forward and edges it straight to James Coles at third slip.
Hampshire 67-1 v Northamptonshire
Nick Gubbins saw an edge drop short of the corden in Jordan Buckingham's last over, this time around he's far more assured and cracks a straight one back past the bowler for a gorgeous driven four.
The run-rate continues to hover around six an over on what looks a lovely day to bat and a frustrating one on which to bowl. Another good toss to win.
Middlesex v Somerset 39-2
That is a shot of real intent from George Bartlett as he pulls a Toby Roland-Jones delivery down to the long boundary.
He and Abell are doing a useful job after the loss of both openers early.
The thing about Lord's is that you do get value for your shots as the surface is usually very true.
Notts v Essex 39-1
Image source, Rex FeaturesStuart Broad is now out of the Notts attack after taking 1-18 from five overs with the new ball.
Dane Paterson is on as first change, but Alastair Cook drives the South African through the covers for four.
Cook is 24 not out - is he in the mood for a 'biggie' today?
Surrey v Kent 35-2
Dan Worrall is in the zone again. He draws a textbook play and miss from Jack Leaning with a ripsnorter. This is going to be another test of Kent's resilience.
Hint of green on the track, a bit of movement from the bowlers, a few silvery clouds hanging about over London on a warm spring day. Good toss to win, you'd think.
Sussex v Glamorgan 25-2
Outstanding over from Ollie Robinson.
He starts with the wicket of Marnus Labuschagne and then almost has Sam Northeast off the last ball as it cuts the Glamorgan batter in half.
The wicketkeeper and five slips certainly enjoyed it!
A wicket maiden.
Sussex v Glamorgan 25-2
England 1 Australia 0!!!!
First ball from Ollie Robinson to Marnus Labuschagne. And that is OUT!!!!
Robinson is right on the money, as he squares up the Australia number three. Robinson and the four slips had not doubts about that one.
What a psychological blow for Robinson to strike over such a key Aussie batter.
Sussex v Glamorgan 25-1
Marnus Labuschagne dabs down his second ball and sets off for a quick single.
Zain ul-Hassan has to get moving and dives in to the danger end as the ball is hurled into the stumps.
Labuschagne will face Ollie Robinson immediately.
Surrey v Kent 30-2
After clipping two sublime boundaries off his pads in the previous over, Zak Crawley has gone two balls into this one.
Jordan Clark slams one in which spits up at the England opener who is a tall man. He cannot avoid an outside edge as he tries to pull his bat away and Will Jacks takes a fine tumbling catch at third slip, diving to his left infront of second slip.
Jack Leaning strides out to join Tawanda Muyeye. Kent are up against it already.
Sussex v Glamorgan 24-1
Eddie Byrom had a life in Aristides Karvelas' first over, but not this time.
Karvelas gets a bit of extra bounce to surprise Byrom and this is a comfortable take for Oli Carter behind the stumps.
In comes Marnus Labuschagne.
