Archie Vaughan picks up his fourth four with a lovely, flowing cover drive off the bowling of Gus Atkinson.

He gets a single off the third ball and Tom Lammonby is beaten outside off stump but survives the over.

Josh Tongue continues to crack it up.

The former Worcestershire quick hit the high 80s in his last over as Oli Carter did his best to keep him out.

There was a glove down to deep third for four off a rib-tickler and another thick inside edge that almost got through to his stumps from a rapid full one.

Tongue's got a leg-slip and short-leg in but Carter gets through it.

James Coles, who watched all that from the other end, enjoys a rare long-hop from Fergus O'Neill (pictured) and dismisses it through mid-wicket for four.

Archie Vaughan survives an LBW shout with a little bit of bat facing James Taylor and he runs a single to the leg side.

Tom Lammonby is beaten by a ball that bounces and leaves him outside the left-hander's off stump.

Lammonby aborts a drive at the last moment off the fifth ball while anchored to the crease.

A Taylor no ball is followed by a ball speared past off stump which Lammonby leaves alone.

Gloucestershire 39-4 v Leicestershire

A fourth wicket for the Foxes as Miles Hammond is caught at third-slip for 11 runs by Rehan Ahmed, off the bowling of Ben Green.

The fall of wickets so far are 1-1, 2-14, 3-21, 4-34 after only 17 overs.

Derbyshire 57-1 v Middlesex

The home-side pass the half-century as David Lloyd on 28 runs and Harry Came on 23 are building a partnership since the first wicket fell on just five.

There's just a little pressure building up here.

Hazy sunshine at the Oval today and the members pavilion is pretty well populated for this game.

Good control from Gus Atkinson in his second spell, getting a consistent line and length just outside off stump.

The last ball of the over is angled in and Tom Lammonby squeezes the ball away late leg side but survives a testing maiden over.

Boy oh boy that outfield is slow. 99 times out of 100 that's a boundary for Tom Nicholls. It gets three quarters of the way and then just... stops.

A four is going to feel like an eight in this match.

James Taylor bowls full and Tom Lammonby defends down the pitch.

Lammonby plays and misses a flashing cut shot as the ball bounces over the top edge.

He's a bit early on a pull shot but still gets the ball away square for a single.

No rest for the Sussex batters.

Brett Hutton is off after another mesmeric opening eight-over spell (3-17), and replaced by Fergus O'Neill, who's had a breather for six overs.

His figs? 0-10 off six overs.

It was 0-6 but James Coles has just edged him streakily through gully to the fence...

Archive Vaughan scrambles a leg bye first ball off Gus Atkinson and Tom Lammonby pulls the bat inside the line to leave a short ball.

The fifth ball is leg side and clipped fine for four, beating Jamie Smith to the rope.

He keeps the strike with a single pushed down the ground.

A double bowling change for the visitors as South African Codi Yusuf is thrown the ball for the 16th over.

Three consecutive overs sent down by bowlers signed in the past couple of days.

Some counties will be very jealous...

Adam Hose survives a shout for LBW from the final ball, might have hit the edge before the pad.

Josh Tongue has surprised me a little bit. I wasn't entirely sure of all the tricks he's got in his armory but he has got that little bit of X-factor.

That was just a rapid yorker that was just too quick for Tom Alsop.

Jack Blatherwick, on loan from Lancashire, replaces Ben Raine and Adam Hose gets off the mark as he helps a leg-side delivery on its way to the boundary for four.

Boundaries have been hard to come by in the opening hour.

The pressure is palpable as the clouds close over New Road.

James Taylor gets a ball to nibble away from a leg stump line and an appeal for caught behind against Tom Lammonby is turned down.

A definite play and miss going forward to block.

Encouraging over for Surrey and now Gus Atkinson is on for his second spell in place of Jordan Clark.

How fantastic has he bowled so far? Ian Holland could get movement off glass.

It's remarkable, even the lengths he's bowling, both opening bowlers are 34 years old, what great experience to bring in.

There seems to be a lot of debate between batters and umpires, lots of warnings.

Gloucestershire looked trapped on the crease.

Archie Vaughan aims a straight drive against Jordan Clark but is blocked by the bowler on his follow through.

There's no stopping his next scoring shot though as he smacks a shorter, wider ball through cover for four.

James Taylor comes into the attack in place of Dan Worrall at the Vauxhall End.

His first ball is turned off Tom Lammonby's hip for four and that shot takes Somerset to 50 in the 15th over.

A solid first hour for Somerset, save for the loss of Sean Dickson, who was forced to retire hurt with a hand injury early this morning.

Jake Ball is finding the edge for fun.

Ben Raine has figures of 0-10 from seven overs and must be casting jealous glances at Jake Ball, who has 3-13 from his six.

The opening duo have bowled nicely but are getting some assistance from the pitch and overhead conditions, plus some slightly nervy Pears batting too, it might be said...

Henry Nicholls has 11 from 21 deliveries after flashing an edge over the slips off Ball.

Dan Worrall continues from the Vauxhall End and Archie Vaughan nudges a single to mid on.

Worrall gets one to cut back sharply past Tom Lammonby, who offers no shot as the ball seams in and bounces over the stumps.

A straighter third ball is pushed to deep third for three.

He continues to get bounce and a bit of away movement outside off stump but Archie Vaughan leaves the ball alone.
