Bopara 5, Wheater 5
Another quiet over from Karl Carver is matched by the virtual silence in the crowd.
They know their side are in trouble here. The required run-rate continues to hover at just under 6.5.
Essex need 178 off 28 overs.
Bopara 4, Wheater 2
Adam Wheater is the new batsman in for Essex.
This innings has followed a very similar pattern to Yorkshire's - the hosts will need a Ballance/Leaning style recovery from these two for sure.
Lawrence lbw b Patterson 15 (Essex 74-4)
Essex are in big bother now.
Steven Patterson gets Dan Lawrence lbw with his second ball.
Lawrence tried to clip a full ball through the leg side but misses and up goes the dreaded finger.
The hosts are four down for not that many.
Lawrence 15, Bopara 3
Image source, Rex FeaturesWhen I strolled out this morning, a 600mph wind smashed into my face. It was dreadful.
Look at it out there now.
Meanwhile, Dan Lawrence plays a wonderful late cut off Karl Carver for his second boundary. Seven come off the spinner's fourth over.
Lawrence 10, Bopara 1
Dreamy from Dan Lawrence.
The 20-year-old takes a step down the wicket and punches Tim Bresnan straight down the ground for four.
Clean as a whistle.
Lawrence 5, Bopara 0
Ravi Bopara is the new man in.
The experienced all-rounder and his younger counterpart Dan Lawrence have plenty of re-building to do.
Chopra c Leaning b Carver 37 (Essex 59-3)
HUGE wicket for Yorkshire. Varun Chopra is caught in the deep.
The Essex opener sweeps Karl Carver straight into the hands of Jack Leaning who takes it easily about 15 metres inside the rope.
It's a big boundary down there - he simply didn't get enough on it. The hosts are in trouble.
Chopra 32, Lawrence 4
The batsmen cannot get Tim Bresnan away.
A couple of singles and two leg byes are all they can muster.
The required run-rate is pushing up towards 6.5 now.
Chopra 32, Lawrence 3
It's easier pickings for Essex off the spin of Karl Carver.
They're still struggling to find the boundary, but collect a comfortable three singles.
Chopra 31, Lawrence 1
Great over again from Tim Bresnan, with only a couple conceded.
Varun Chopra now has 522 runs in this competition - only 15 behind the leading scorer - Kent's hero earlier today, Heino Kuhn.
Essex will still be hopeful while Chops is in the middle.
Chopra 29, Lawrence 1
Image source, Rex FeaturesYorkshire introduce spin for the first time as Karl Carver replaces Ben Coad.
Varun Chopra and Dan Lawrence are able to pick him off for three singles and a couple of runs to keep things ticking along.
Chopra 25, Lawrence 0
Brilliant from big Tim Bresnan. A maiden.
It's turned into a glorious evening in mid-Essex - hardly a cloud in the sky. It doesn't get much better than this folks!
Chopra 25, Lawrence 0
Varun Chopra will have to forget about that run out quickly - he's still got a mammoth job on his hands.
The opener punches Ben Coad through the covers for four.
Dan Lawrence is his new partner, fresh from a hundred in the last game.
Image source, Rex FeaturesWestley run out 2 (Essex 35-2)
Oh dear, Tom Westley has been run out backing up...
Varun Chopra biffs Ben Coad back down the pitch, Coad gets a finger tip on the ball and it clatters into the stumps.
Westley is an inch out of his ground. It's unlucky, but Yorkshire won't care a jot.
Chopra 18, Westley 1
Tim Bresnan enters the attack and Tom Westley gets off the mark from his ninth delivery with a clip behind square.
Two off the over, and things remain tight.

The football's done now - it's all about the action from Chelmsford.
Chopra 17, Westley 0
That's the best shot of this innings so far.
Varun Chopra simply eases the ball from Ben Coad over mid-wicket and it skips to the rope.
The other five deliveries are on the money though and just the four come from the over. Powerplay one is done - it's been Yorkshire's.
Chopra 13, Westley 0
Another excellent over from Matt Fisher as just the single comes from it.
Yorkshire have really turned the screw early on here as they defend what is usually a below-par total at Chelmsford.
Chopra 12, Westley 0
Tom Westley clips his first ball straight to mid-wicket.
That's the end of a wicket-taking over for Ben Coad.
Cook c Patterson b Coad 11 (Essex 26-1)
The pressure told - that's not an Alastair Cook shot.
The former England captain goes for a huge mow, but can only sky Ben Coad to Steven Patterson at mid-off.
He slumps off, frustrated. Stand-in skipper Tom Westley is the new man in.
