Psychological barrier No1 breached, as Dean Elgar and Tom Westley have chipped the deficit down to below 300.

Still slow-going at Chelmsford.

Middlesex have lost a second wicket with Luke Hollman caught off Zak Chappell, but Josh de Caires is now 43 not out in their 83-2 against Derbyshire.

Lancashire have progressed to 85-2 at Canterbury, replying to Kent's 293 all out, with Luke Wells on 39 not out.

Glamorgan just miss out on the fifth batting bonus point but are still in a near impregnable position.

The landmark arrives in the 117th over as Mason Crane pulls a short ball from Ben Whitehouse through mid wicket.

Two overs later Crane is celebrating a 50 partnership in 81 balls with James Harris, who drives Whitehouse to cover off the back foot for one.

Will Young times a back-foot cut nicely past backward point to the rope to move to 62* and then tries to glove one down the leg side, not quite getting contact, but the ball flies to the rope for four byes.

Expensive over from Jordan Clark as Michael Booth flashes the final ball through the covers for another boundary, 13 off the over, 200 up for Warwickshire, the deficit is down to 46. 50 runs from a batting bonus point.

A short ball from Matthew Revis is pulled in the air by Lewis Goldsworthy but the backward square leg fielder doesn't spot it and four runs take the Somerset total past 200.

A couple of anxious moments already for the Leicestershire openers.

Rishi Patel edges the final ball of Matt Taylor's opening over, but it doesn't quite carry to Miles Hammond at third slip, who can only parry and concedes two runs.

Ajeet Singh Dale has the new ball at the other end and whistles his last delivery past the edge of Sol Budinger's bat.

Shot! Jack Carson nails a slog sweep over square leg for four runs off Bjorn Fortuin and that brings up the innings 100 in the 44th over.

Carson tries to get the ball away off the back foot and through the off side but doesn't clear the field.

He gets away with a very tight single into the off side from the fifth ball after a fumble in the field from James Fuller.

At one stage both batters were stuck halfway down the pitch.

Just signs that Dean Elgar and Tom Westley are starting to play more expansively in the past couple of overs.

Elgar picks up a couple of boundaries to move to 17*, though Sam Conners comes close to finding the outside edge of his bat with one which moves in the air to end his latest over.

Tom Taylor is back in the attack for the Pears and immediately draws Joe Clarke forward with a play and miss outside off stump.

Clarke is beaten again and squared up by the third ball but recovers to drive the fifth through mid on for two and that gets Notts to 100 in the 35th over.

It also brings up a 50 partnership with Freddie McCann in 94 balls.

It didn't go their way in the field - how will the Division Two leaders fare with the bat? We are about to find out.

Rishi Patel and Sol Budinger are the two openers and Matt Taylor will open the bowling for Gloucestershire.

Michael Booth faces five balls without scoring but decides to cut loose to one from Jordan Clark which is short of a length just outside off.

He flashes a drive which flies past the diving fielder at backward point and all the way to the rope.

Will Young runs three after getting up on his toes to cut Tom Lawes square to the deep to start the next over and the deficit is down to 65.

Tom Alsop is back on to his stumps to defend as late as possible against the left arm spin of Bjorn Fortuin.

He goes for a reverse sweep and gets four to reach 33.

The next ball is pushed into the off side but Jack Carson turns down the single - which was not there anyway.

Good flight and dip from Bjorn Fortuin and Jack Carson blocks from the crease.

Keith Barker continues from the other end, conceding just one and bowling a good line, just back of a length.

Sussex have been pegged back by some excellent Hampshire bowling which has seldom been loose.

Dan Mousley did have to play at that one. There was quite a variety of lines in that over from Jordan Clark coming quite wide on the crease.

Again a wicket that brings the game back seemingly towards about level.

Will Young is going to need some help from the Warwickshire lower order.

We thought Somerset had freed themselves with those two Lewis Goldsworthy boundaries but no - Yorkshire have slammed down the shutters again.

There have been 17 overs bowled this morning and only 29 runs added.

Oof. Big shout from Sam Conners as Tom Westley plays across the line to a quick delivery and misses, the ball thumping him infront high on the pads... too high? Umpire James Middlebrook thinks so.

Westley survives.

Durham turning up the pressure at Chelmsford, however.

10 overs gone and Essex are 19-1.

Dean Elgar had four scoring shots in his first 33 deliveries but punches Matt Potts to the boundary to move to 9* with skipper Tom Westley 6* from 10 balls.
