David Bedingham makes 79-ball 100 for Durham against Worcestershire
Hampshire's Liam Dawson takes five-for against Warwickshire
Surrey reach 185-1 at the close against Kent, with Dom Sibley 87 not out
England's Harry Brook out first ball for Yorkshire at Lord's
Marcus Harris scores 214 for Leicestershire at Derby
Ricardo Vasconcelos hits unbeaten 166 for Northants v Glamorgan
Worcs 110-5 v Durham 244
Apologies, Pears fans for tempting fate about how well Worcestershire had started.
Jason Holder and Jake Libby's partnership had been looking good, they were hitting a few boundaries and looked set for a good session.
But Ben Raine upsets the applecart by bowling the West Indies man and all of a sudden there is a different complexion on the game.
Northants v Glamorgan 236-8
You won't see many better catches than that.
Ben Sanderson finds the edge of Colin Ingram's bat and Karun Nair dives to his right at first slip to take it one-handed.
Fabulous effort by the Indian and it ends a stand of 65 for Glamorgan's eight wicket. Ingram faced 125 balls and hit a six and nine fours.
Essex 100-1 v Lancashire 146
Dean Elgar pushes a Tom Bailey delivery through the legside and those couple of runs pick up the 100 for the home county.
They are just 46 runs behind and hold all the aces in this match.
Middx 115-5 v Yorks 159
A double blow for Middlesex at Lord's.
Ryan Higgins is bowled for nine by an absolute jaffa from Ben Coad and in the next over Stevie Eskinazi edges Jordan Thompson and Adam Lyth takes his second good catch of the morning - he's surely one of the safest slip fielders around.
Yorkshire have now taken three wickets for 17 runs, but Leus du Plooy is still there on 41 not out.

Worcs 104-4 v Durham 244
Big shot from Jason Holder as he frees his arm to pull the last ball of a Ben Raine over for six.
That also takes Worcestershire over the threshold of 100 runs.
Jake Libby has moved on to 45 and the Pears have started well in Kidderminster.
Kent 144-4 v Surrey
Another boundary for George Garrett as he runs Kemar Roach down to third man off a thick edge. No chance there, it was all along the ground.
Garrett adds two off the next ball but rain has now arrived and they are heading off the field.
Essex 91-1 v Lancashire 146
A good punch down the wicket brings Dean Elgar four runs and he is now on 30.
South Africa's lack of Test cricket is Essex's gain as they have got him for two whole seasons.
An excellent replacement for the retired Sir Alastair Cook.
Leicestershire have lost their first wicket of the day at Derby with Lewis Hill caught at second slip off Sam Conners for 47, leaving them on 184-3.
Glamorgan's overnight pair are still together against Northants, with Colin Ingram 78 not out and Mason Crane on 35, in their score of 232-7.
Zafar Gohar has reached a 79-ball 50 for Gloucestershire at Hove with a cover drive for two off Ollie Robinson. They are 358-8 and Gohar and Zaman Akhter have reached a 50 partnership.
Hampshire v Warwickshire 356-4
After 26 overs yesterday, Liam Dawson is thrown the ball early today by Hampshire captain James Vince.
His first over gives up two singles off the first five balls, before Danny Briggs sweeps the last one for the first four of the day.
Somerset 127-2 v Nottinghamshire 193

Getting a wicket relatively will give Notts a boost
That was Luke Fletcher's 449th first class wicket and he'll be grateful to Jack Haynes for taking the catch.
Kent 133-4 v Surrey
Well, well, well.
Tom Lawes tests George Garrett out with a bouncer and the left-hander swivels to pull it away for four.
Lawes repeats the tactic next ball with the same result and kicks the ground in frustration. The Surrey paceman's dander is now up.
Somerset 126-2 v Notts 193
A wicket, and a much-needed one for Notts as Luke Fletcher removes Sean Dickson.
The Somerset opener only adds two to his overnight total as he swings at an outswinger from Fletcher and catches it very well but sends it straight to Jack Haynes.
It's still a good take from the fielder as that was travelling.
Hampshire v Warwickshire 350-4
It is a day for coats at the Utilita Bowl, although we can spot a spectator in shorts. Klaxon!!
However, the man's decision to dig in his bag and put a woolly hat on probably tells us more about the Southampton weather.
On the field, night-watchman Danny Briggs squirts out to deep point and the single brings up the 350 for Warwickshire and their third batting point.
Middx 97-3 v Yorks 159
Mark Stoneman, beaten outside off stump the ball before, pushes at an angled delivery from Jordan Thompson and Adam Lyth swoops at second slip to take the catch just millimetres above the turf.
Yorkshire have the breakthrough and that ends a stand of exactly 60 with Leus du Plooy, who has now been joined by Ryan Higgins.
Kent 117-4 v Surrey
A nighthawk he isn't.
Kent badly need George Garrett to stick around and he is doing his best to keep Surrey at bay in these initial overs.
Tom Lawes temps him outside off stump with a full length delivery, but the left-hander makes no contact with a tentative prod.
Essex 83-1 v Lancashire 146
George Balderson, coming round the wicket, hits Dean Elgar on the pads. It's a half-hearted appeal as Elgar is probably outside the line.
Next ball, he digs it in and the ex-South Africa opener pulls it through leg to the boundary, the first of the day.
Then when Balderson offers a bit of width, Elgar guides it low past gully for another four.
Hampshire v Warwickshire 345-4

I wouldn't say it's warm but it is a pleasant day for cricket.
Warwickshire batted well yesterday but they haven't completed the job.
Gloucestershire have added 22 to their overnight total at Hove and are 341-8 in the 93rd over, with Zafar Gohar now 39 not out.
Glamorgan's overnight are also still together at Wantage Road, with their total 209-7 in the 59th over. Colin Ingram is 75 not out.
Tight bowling by the home side in the opening overs at Derby, where Leicestershire are 172-2 with Marcus Harris on 77.
Worcs 87-4 v Durham 244
Durham hands go up in appeal as they think they've got an early breakthrough against the hosts by taking the wicket of opener Jake Libby.
Matthew Potts tries his luck with an lbw appeal alongside his team-mates but the umpire remains unmoved.
It looks like it was going well down leg to be honest.
And Jason Holder gives the umpire some assistance by pointing that out with a few arm gestures!
Kent 111-4 v Surrey

We came here in the bright sunshine and the game starts at 11:00 and these filthy, dirty grey clouds have come over and the sky is a battleship grey somewhat.
