LV=CC, May 1: As it happened
6:30pm - We have reached the close of play at all seven games, most notably at Chelmsford where Essex recovered from 31 for six to chase 143 without further loss.
Several batsmen round the country are unbeaten on impressive scores, including Trott on 87 and Lumb on 77.
@EssexCricket on Twitter: Paul Grayson "It was nice to get a win... it was a good cricket wicket... as a bowling unit we were excellent..
On day three at Trent Bridge, Nottinghamshire are 145 for five in their second innings, trailing by six runs.
Yorkshire are 597 for five on the third day at Headingley, replying to Derbyshire’s 475 all out.
Warwickshire are 276 for four at the BrightonandHoveJobs.com County Ground after choosing to bat on the opening day of their match with Sussex.
Essex beat Hampshire by four wickets at Chelmsford.
Leicestershire are 32 for two in their second innings, leading Gloucestershire by two runs at Grace Road.
Glamorgan are 110 for four on the first day at Colwyn Bay, replying to Lancashire’s 123.
Kent were 271 all out after opting to bat against Northamptonshire at Canterbury.
6:24pm - RESULT! Hampshire (197 & 199) have lost by four wickets to Essex (254 & 143/6) at Chelmsford: Napier and Pettini, who were unbeaten on 78 and 35 respectively, have seen Essex to their first championship win of the year. Napier’s innings occupied 88 balls with 10 fours and three maximums.
6:15pm - Copeland, having bowled Charlie Shreck for nought, has a five-for as Kent are dismissed for 271.
@HantsCricket on Twitter: 100 partnership is up for Pettini (28*) and Napier (68*) and it looks bleak. Essex, 130-6, require 13 to win and have an extra half hour.
6:05pm - Copeland removes Mark Davies as Kent slip to 271 for nine.
Stumps are being drawn around the grounds, but not at Chelmsford where Essex need 22 to win with four wickets left.
Bairstow, the ball after hitting his fourth six, falls to Wes Durston for 186 from 193 deliveries, featuring 21 fours. He added 117 for the fifth wicket with Gary Ballance, who ended unbeaten on 50.
5:59pm - Warwickshire’s decision to send out Chris Wright as a nightwatchman has backfired with Jordan snaring him in the same fashion as Bell for his second wicket in two overs. Tim Ambrose is the new man alongside Trott.
Napier goes to a fifty and then smacks James Tomlinson for the batsman’s second six of the innings followed by a four.
5:49pm - Bell is out for 56, caught behind off Chris Jordan but Warwickshire are still well placed on 272 for three.
Having surprisingly replaced Kerrigan, Anderson has his third wicket of the day - pinning Marcus North in front for 22. Lancashire could keep Glamorgan to a similarly low first-innings score as their 123.
Gareth Breese has Steven Mullaney held at slip, making Notts 136 for five and still 15 behind Durham.
@HantsCricket on Twitter: Essex reach 100-6 so only 43 more are required for a win. A wicket for Hampshire feels pretty vital now! (Pettini 22*, Napier 48*)
5:40pm - Leicestershire are in further trouble as Gidman gets his second wicket, trapping Niall O’Brien in front. Glamorgan are 88 for three with Simon Kerrigan having Will Bragg lbw in his first over.
Kent have lost two wickets in two overs to be 250 for eight, Trent Copeland snaring Matt Coles for nought and catching James Tredwell off David Willey for 19.
@HantsCricket on Twitter: Napier (45*) is starting to turn it on, hitting the second six of the match (he also hit the first in 1st ins!) Essex 91-6 (52 reqd to win)
5:32pm - Ian Bell, captain of Warwickshire this week, follows Trott to a half-century. It really has been a good day for the reigning LV= County Champions, who have moved on to 258 for two.
@EssexCricket on Twitter: 10 in an over from Balcombe that brings up the 50 partnership in 14 overs. Pettini 17, Napier 36. Essex 82-6 need a further 61 runs to win
5:23pm - Leicestershire's second innings starts woefully as Michael Thornely follows yesterday's second-ball duck with a first-baller! Gidman is his nemesis once again.
Geraint Jones has been sent packing for 20 at Canterbury, a second scalp for Trent Copeland.
Bairstow now has 150 to his name. How many will Yorkshire end up with?
@CricketingBears on Twitter: Hundred partnership between Bell and Trott Bears 246-2
5:09pm - MCC have announced a 'masterplan' for the development of Lord's, which will see the Warner, Tavern & Allen, Compton and Edrich Stands rebuilt and an increase in capacity to 32,000. The Nursery Ground will also be resited and the pavilion extended.
Gloucestershire are all out for 280, with Taylor adding 61 not out to 52s from Benny Howell and Will Gidman.
It is rapidly turning into the Mark Wood Show at Trent Bridge. The youngster has dismissed Samit Patel to strengthen Durham's position.
Yorkshire have moved beyond 500...
5:01pm - Hang on a minute, Root is out! His wonderful innings of 236 came to an end when he was bowled round his legs looking to sweep Redfern.
Wood has another for Durham; James Taylor made 97 in his first knock at Trent Bridge but has fallen for one second time around to leave Notts in big trouble, 62 behind on 89 for three.
In case you're wondering, there have been no further wickets at Chelmsford, with Essex belatedly steadying the ship. They are 53 for six in pursuit of 143.
5pm - Yorkshire have overhauled Derbyshire's 475 at Headingley and, with only three wickets down, now have the opportunity to pile the pressure on their visitors heading into the final day.
Gloucestershire continue to extend their first innings, moving 25 ahead of Leicestershire as Craig Miles offers good support to half-centurion Taylor.
@LancsCCC on Twitter: Just had an interesting one here at Colwyn Bay. Stumps thrown down with Bragg out of his ground. Given not out because he was evading ball
4:45pm - With Yorkshire continuing to attack, Bairstow has been given a life by part-time spinner Dan Redfern, who put down a return chance. Root, meanwhile, has a new career-best score after moving past 222.
Mark Wood follows up his lower-order runs for Durham with the wicket of Cowan, who is caught behind for 35.
Gloucestershire have crept into the lead at Grace Road, overhauling Leicestershire's 250 for the loss of nine wickets. Jack Taylor is one shy of 50 and it has been quite a recovery from the visitors' lower order.
@derbyshireccc on Twitter: Root (215*) and Bairstow (111*) complete the 200-run partnership. Yorkshire 446-3 (121.2 overs) trail Derbyshire by 29 runs
4:39pm - Crook claims another big wicket for Northants, accounting for Kent's other half-centurion, Daniel Bell-Drummond. With the second new ball not too far away, the Canterbury hosts are 216 for five.
Anderson has also picked up another, bowling Stewart Walters for 15 to herald the arrival of former Lancashire overseas player Marcus North.
4:30pm - Bairstow has put his foot down, finding the rope from three successive Wes Durston deliveries. Root then picks up back-to-back boundaries off David Wainwright before his partner moves into three figures with four off the same bowler. Well batted Jonny lad!
Amazingly, Essex have lost another wicket to a run-out, with Foster falling victim to George Bailey's direct hit. That makes it 31 for six at Chelmsford!
Nottinghamshire have recovered well from the early loss of Alex Hales, moving to 71 for one through Ed Cowan and Michael Lumb. However, they still trail Durham by 80.
@HomeofCricket on Twitter: MCC Head Coach Mark Alleyne has just stepped out to bat against his MCC Young Cricketers team at Lord's. This could be fun!
4:20pm - Essex fans may wish to stop reading. Two more wickets have gone down at Chelmsford! Tomlinson had Rob Quiney caught behind for his second scalp before trapping Ben Foakes lbw for a golden duck. The hat-trick delivery is seen off by James Foster, but his side find themselves 24 for five chasing 143.
Northants have struck again at Canterbury, Steven Crook ousting Mike Powell for 70.
Robbie Williams has a third wicket for Leicestershire, who have the chance to claim a slender first-innings lead with Gloucestershire 230 for nine in reply to 250.
4:14pm - Joe Root will not be shifted. We`ve already had an unbeaten 270 at Headingley this week from Chesney Hughes and Root now has 200 to his name! Yorkshire are 399 for three with Jonny Bairstow closing on a century of his own.
If England team director Andy Flower is pleased by that, he will also be happy to see that Jonathan Trott has passed 50 for Warwickshire, who remain well placed on 198 for two against Sussex.
4:06pm - Things go from bad to worse for Essex as Ravi Bopara is caught at second slip off David Balcombe for a duck! That makes it 16 for three. My oh my!
James Anderson has struck an early post-tea blow at Colwyn Bay, Ben Wright edging through to Gareth Cross with the score on 12.
@hantscricket on Twitter: WICKET: A misfield creates confusion in the batters and Westley (8) is run out! Bailey takes the credit / blame?! Essex 16-2 - still 127 reqd
3:58pm - There has been an early wicket in Essex’s run-chase and it’s a big one. Cook is bowled through the gate by Balcombe for four in the second over. Nervy moments for the hosts.
Tea is being taken at all the other grounds. Here are the scores as they stand.
On day three at Trent Bridge, Nottinghamshire are 45 for one in their second innings, trailing by 106 runs.
Yorkshire are 385 for three on the third day at Headingley, replying to Derbyshire`s 475 all out.
Warwickshire are 190 for two at the BrightonandHoveJobs.com County Ground after choosing to bat on the opening day of their match with Sussex.
Essex are 12 for one needing a further 131 runs for victory against Hampshire at Chelmsford on day three of their fixture.
Gloucestershire are 219 for eight on day two at Grace Road, replying to Leicestershire’s 250.
Glamorgan are seven for none on the first day at Colwyn Bay, replying to Lancashire’s 123.
Kent are 195 for three after opting to bat against Northamptonshire at Canterbury.
3:46pm - Yorkshire will be pleased with their work as they take tea with Bairstow unbeaten on 74 and Root just nine runs short of a double-century. The hosts are 385 for three, still 90 runs behind Derbyshire, but have missed out on their fifth bonus batting point.
Tom Westley and Alastair Cook have emerged from the pavilion as Essex hope to secure their first victory of the season, while Howell has gone for 52 at Grace Road, lbw to Claude Henderson. Howell struck just three boundaries in 160 deliveries and over three hours at the crease but his team-mates won’t mind, as the visitors edge closer to Leicestershire’s 250 having been 46 for five earlier in the day.
No early wicket for Lancashire meanwhile...
3:35pm - Bopara finished with figures of 4-41 but Masters is the man to take most credit for a fine Essex bowling effort, ending with magnificent match figures of 9-70. Essex will need 143 to win when they return from tea.
3:31pm - Buoyed by their late flourish with the bat, Durham are already among the wickets at Trent Bridge with Alex Hales bowled by Chris Rushworth for none in the second over.
Hampshire have lost their final five wickets for 11 runs. First, Masters claimed his fifth wicket of the innings and ninth of the game with Wheater edging behind for 14. Bopara then took two wickets in four balls to wrap up the innings. David Balcombe was caught by Rob Quiney at gully for two before James Tomlinson was snapped up by Foster for a duck. A clinical bowling effort to dismiss the tail means tea is now being taken at Chelmsford.
Benny Howell’s patient Gloucestershire innings has earned rewards as he remains unbeaten on 51; Bell-Drummond has his fifty as Kent make good progress.
Yorkshire are moving on in similarly serene fashion on a flat track at Headingley where Root and Bairstow are enjoying an unbeaten century partnership.
3:15pm - The end of Durham’s innings has coincided with the final wicket of Lancashire's first innings falling at Colwyn Bay. Marcus North took just two deliveries to have Kerrigan caught by Allenby at slip for seven, leaving Anderson unbeaten on 11 as the visitors are made to settle for a paltry 123. A great effort from the Glamorgan attack who have completed their business inside 53 overs.
Chris Nash has made an important breakthrough for Sussex with Chopra caught behind by Matt Prior for 87. Chopra’s departure means Trott is joined by England colleague Ian Bell.
The new ball is paying dividends at Chelmsford where Vince and Chris Wood have both been dismissed. Vince made 67 before edging Masters through to James Foster before Bopara trapped Wood lbw for two. The hosts require just three more wickets.
Moments after celebrating his half-century, Gidman was returning to the pavilion after he fell lbw to Jigar Naik at Grace Road.
Plenty of great action across the country...
3:06pm - There has been a flurry of fifties as bat begins to dominate ball in a number of today’s encounters.
Wood hits a six off Steven Mullaney to bring up his half-century before the Nottinghamshire all-rounder has Onions caught by Samit Patel for 26, bringing to an end an enjoyable wag of Durham’s tail. The visitors made 471, a 151-run first-innings advantage.
Jonny Bairstow is acknowledging the applause at Headingley. There have been four fours and a six in a timely knock for the England international as he tries to find form ahead of the Lions game against New Zealand next week.
Will Gidman took just 53 balls to notch his fifty in a sprightly innings which has featured eight fours.
At Canterbury, Powell reached his half-century before shaking hands with Bell-Drummond on a century partnership.
@Yorkshireccc on Twitter: Derbys seamer Tony Palladino has suffered a side strain and is not on the field. Yorks 339-3, Root 173, Bairstow 48
2:44pm - An unbeaten 44-run 10th-wicket stand between Mark Wood and Graham Onions has given Durham a 125-run lead at Trent Bridge.
The final wicket is also proving difficult for Glamorgan to capture with Simon Kerrigan and James Anderson offering late resistance for Lancashire.
2:34pm - David Masters has the new ball in his hand at Chelmsford with the hosts looking to make inroads into Hampshire’s lower order. Vince and Adam Wheater have moved their lead onto 119 with five wickets remaining.
Derbyshire have also taken the new ball at Headingley where Root and Bairstow have taken the score comfortably beyond 300.
Trott is digging in against Sussex with 10 from 47 balls, exchanging a few words with Chris Jordan after a spell of short-pitched bowling. Ed Joyce has brought Monty Panesar into the attack as the home side attempt to break the unbeaten fifty partnership for the second wicket.
2:22pm - Durham passed 400 against Nottinghamshire at Trent Bridge before Gareth Breese fell lbw to Stuart Broad for 44. Those were really useful runs from the West Indian, helping the visitors move towards a handy first-innings lead.
Bairstow executes a neat reverse sweep off Wes Durston to notch his 4,000th first-class run before planting David Wainwright into the stands. Yorkshire seemingly trying to up the tempo after lunch.
Wickets continue to tumble at Colwyn Bay where Glover has three wickets in nine balls. This time it’s Kyle Hogg trudging back to the pavilion, lbw for two. The following over, skipper Glen Chapple goes for five, caught by Jim Allenby off Michael Hogan, leaving the visitors in real trouble.
@Yorkshireccc on Twitter: Root has reached his 150, off 219 balls and including 17 fours. Yorks 285-3 in 87 overs with Bairstow unbeaten on 16
2:11pm - Things have gone from bad to worse for Lancashire with Katich caught behind by Mark Wallace for 19 as Glover prises his second wicket of the innings. Luke Procter’s 26 remains the visitors’ highest score today with Glamorgan enjoying life on the North Wales coast.
Kent are beginning to shake off their poor start to the day against Northamptonshire at Canterbury with Mike Powell and Daniel Bell-Drummond accumulating a welcome fifty partnership for the fourth wicket.
Joe Root has 150 at Headingley giving the 22-year-old 381 runs from three championship knocks so far this summer. Impressive stuff.
2:01pm - James Vince’s excellent start to the season shows no sign of stalling. A big century against Leicestershire was followed by a fifty against Worcestershire, and the 22-year-old is in the runs once more against Essex. He’s 51 not out with the visitors leading by 107 runs with five wickets remaining at Chelmsford.
Gloucestershire have been dealt a blow in their attempts to reach parity with Leicestershire’s 250 as Hamish Marshall falls lbw for 47. The New Zealand international is Ollie Freckingham’s fourth victim of the innings with the visitors 107 for six.
Lancashire are limping to three figures with Cross now gone, lbw to John Glover, for nine.
1:53pm - Hampshire have suffered an early setback against Essex with Sean Ervine gone for two, bowled by Graham Napier.
Chopra has followed up last week’s century against Somerset with an unbeaten fifty. The former Essex man brought up his half-century with the eighth four of his 119-ball innings.

@CricketingBears on Twitter: Trott dropped off Anyon by Joyce but Bears lunch on 83-1 Chopra 46 Trott 2
12:52pm - Not content with a five-wicket opening-day haul, Benny Howell is now playing his part in a restorative sixth-wicket stand for Gloucestershire at Grace Road. He and Hamish Marshall have shared a fifty partnership to take their team into three figures after a trio of cheap wickets this morning.
12:42pm - Smith's fine innings has come to an end. Samit Patel has got rid of the Durham batsman, whose 153 spanned 393 balls and 505 minutes.
Steven Croft is the fifth Lancashire batsman to depart prior to lunch at Colwyn Bay, caught by a diving Murray Goodwin at midwicket to become Michael Reed`s second victim.
Once again we see a flurry of wickets all at once. Yorkshire skipper Andrew Gale has gone cheaply to David Wainwright, while Hampshire's Dawson has fallen to a fine catch at short-leg from Essex's Ben Foakes. That leaves Hampshire on 144 for four.
@SussexCCC on Twitter: WICKET..Anyon gets one to shape away from Porterfield who edges to Jordan at first slip. Gone for 33. Warwickshire 67/1
12:35pm - Durham's Smith may have struggled on his previous returns to Trent Bridge, but he now has 150 to his name against his former club. The visitors' lead is up to 34 and they still have three first-innings wickets in hand.
@Yorkshireccc on Twitter: Gale offers a slight chance, edging Wainwright between wicketkeeper and slip on 1. Yorks 242-2 off 70 overs, Gale 3, Root 125
@LancsCCC on Twitter: OUT! Now Prince goes lbw and Lancs are in a bit of bother. Reed with the wicket, and are 54-4.
12:20pm - Luke Procter looked good this morning, but has now fallen for 26, lbw to Jim Allenby. Both Division Two sides who chose to bat this morning are therefore three down for not much more than 50.

12:04pm - New Zealand have arrived on English soil for their tour ... and Kane Williamson looks delighted to be here.
11:58am - It is fair to say Joe Root is in decent nick at present. The England batsman, who will captain the Lions against New Zealand next week, made a match-winning 182 at the Emirates Durham ICG last time out and has now moved to three figures against Derbyshire. With Phil Jaques also going well, Yorkshire have passed 200 for the loss of one wicket in reply to their opponents' 475.

Yorkshire continue to tick along nicely at Headingley. Joe Root is 12 shy of a century in a home total of 190 for one.
@CricketingBears on Twitter: Andy Miller bowling at one end and James Anyon at the other....where have I seen that before??
11:24am - Stuart Broad has ousted Phil Mustard at Trent Bridge, which means Durham are 313 for seven in reply to Nottinghamshire`s 320 all out. Mustard put on exactly 50 with Will Smith, who remains unbeaten on 129.
The first wicket of the day has arrived at Canterbury as well, with David Willey, one of the form bowlers on the county circuit, bowling Sam Northeast for 10.
Hogan has claimed a second scalp at Colwyn Bay, cleaning up Karl Brown to put Lancashire in a pickle.
And the wickets keep on coming for Gloucestershire, Freckingham enjoying success again with the removal of Alex Gidman. Gloucestershire are now 46 for five.
