Not a great ball from Kasey Aldridge, but it's a lovely shot from Tom Curran.

The England white-ball all-rounder times it beautifully and dissects the gap between deep cover and deep backward point for his third four. To go with his SIX sixes.

A single takes him to 57 off only 49 balls and cuts the gap to 30 runs.

Colin Ackermann gets a single on the back foot through cover off Tom Hartley.

David Bedingham facing on 247.

He gets a single to keep the strike turned to the on side. 248 now.

Luke Wells bowls a big full toss outside off but Bedingham misses a drive.

Bedingham scoops the third ball to leg for a single.

Single to Ackermann.

Driven down the ground for one and there's the 250! It's actually his second 250 for the club having also reached the landmark three years ago against Derbyshire.

324 balls with 26 fours and a six.

How's your luck?

A Kemar Roach edge flies between Ben Green and leg slip, much to the chagrin of bower Kasey Aldridge.

It brings up the 50 stand off just 53 balls. Roach has five of them!

Four more runs to David Bedingham, carving Luke Wells away through third man.

That's the 400 partnership for the fifth wicket with Colin Ackermann in 553 balls.

He gets a single off the fifth ball to move to 246.

Just a reminder that lunch is a little later today at !2:40 at Worcester, with 104 overs due to be squeezed in today following yesterday's dampness.

After all Worcestershire's early wicket-taking antics, things have settled down a bit.

Bears skipper Alex Davies has really got his head down. Just nine runs in 38 balls, while Will Rhodes is a little more fluent, having hit four fours so far in his 24 - the last of which went way too close to midwicket's hands for comfort.

At least their efforts have given the visitors a little more stomach to face their lunch.

Luke Hollman is having a bowl and starts with a maiden over.

Zafar Gohar is across to sweep Josh de Caires and misses.

Close to LBW but just sliding down.

The fourth ball is worked to mid wicket for one.

Zaman Akhter gets a wide ball and misses with a flashing drive.

No footwork there.

It's worth remembering the calibre of batters that Archie Vaughan has removed this morning and yesterday.

The 18-year-old's six first-innings victims include England trio Rory Burns, Dom Sibley and Ben Foakes no less. No wonder his team-mates have been all over him.

Dad will be proud.

Meanwhile, Somerset decide not to give Lewis Goldsworthy a second over after his first went for 18 runs.

The pace of Kasey Aldridge replaces him.

David Bedingham sweeps Tom Hartley behind square for two.

Colin Ackermann keeps the strike with one through point on the back foot.

Now Luke Wells is going to have a bowl.

Ackermann and Bedingham trade singles until the fourth ball, which is tossed right up and hammered through cover by Bedingham for four.

Nine runs off the over in total. The lead is 258.

Liam Dawson slow it down to squirrel a way between Charlie Stobo's bat and pad and knock back his stumps.

It might be about time for openers Ben Compton and Tawanda Muyeye to dig out their pads again.

Kent are 257 in arrears still and running out of batters

That begs the question, will Michael and Archie Vaughan become England's greatest father and son duo? The Broads, Stewarts, and Bairstows might have something to say about that, but what do you reckon?

Henry Brookes continues from the Pavilion End with two cover fielders in place.

The third ball is pushed through backward point on the back foot for a single.

Single to Zaman Akhter, glancing to leg and Zafar saves the follow on tickling a leg side ball fine for four.

Can't keep up with it at Chelmsford!

Half joking a little while ago when we said Notts might not make it to lunch - but could turn out to be bang-on.

Lyndon James, Luke Fletcher and Liam Patterson-White all depart in the space of 11 Essex balls, all to Jamie Porter who has fantastic figures of 5-35. Just missed out on a hat-trick too.

Somerset 317 v Surrey 271-8

Wow, wow, wow!

Lewis Goldsworthy comes into the attack for his first bowl and perhaps wishes he hadn't bothered.

Tom Curran welcomes him by smacking a knee-high full toss for a big six.

He then plonks his fourth ball for another six and two balls later, brings up a remarkable 33-ball half-century by smashing another monstrous blow into the Marcus Trescothick Pavilion.

It's just his sixth first-class fifty and is quickly changing the tone of this game.

Billy Root takes strike as Glamorgan look to fare better in their second knock.

Asa Tribe watches on from the non-strikers as Ollie Robinson steams in.

Another Michelle for Kyle Abbott.

No.26 in the County Championship, all for Hampshire, and third of the season.

Harry Finch chases a very wide one and it is simple for Ben Brown to get hold of with the gloves. 44 off 91 balls for the Kent batter.

Pressure is right back on Kent now.

Tom Curran continues to take the attack to Somerset as he takes a third six off Archie Vaughan.

He then crashes a lovely cover drive off the spinner to move Surrey past 250 for a first batting point.

Curran skips along to 32 and the deficit is 64.
