Farhan Ahmed moves across to flick Jayden Seales leg side for his first run past short leg off his 11th delivery.

Josh Tongue leans back to evade a bouncer and then ducks under a shorter bouncer next ball.

Ahmed will face Ollie Robinson.

Codi Yusuf is dismissed for one, caught behind off Jacob Duffy, and the session is over.

Worcestershire lead by 26 after the first innings.

Fascinating afternoon session to come in 40 minutes or so.

Jake Ball batted nicely for his 13* but will be back with the ball in hand, aiming to follow up his first-innings fivefer on debut.

Ian Holland made it to 50* from 135 balls on the stroke of lunch at Bristol as Leicestershire reached 189-5, still trailing Gloucestershire by 63. Holland has added 70 for the sixth wicket with Ben Cox (27*).

Luis Reece also has a half-century for Derbyshire, joining Martin Andersson (65*) to add 120 for their sixth wicket against Andersson's former side Middlesex, reaching 369-5 at lunch at Derby.

Notts 284-9 v Sussex 169

With Notts nine down we are going to play on past 1pm.

Josh tongue misses an attempted drive off Ollie Robinson and the ball just misses the outside dege.

He steps away to the last ball and misses an attempted heave to leg and that ball thuds into his shoulder.

Lewis Gregory brings himself back on, this time from the Vauxhall End and Dom Sibley is forward to the Somerset captain to defend.

Sibley deflects a ball off his thigh pad for a leg bye.

Rory Burns sees out the over and that's lunch.

A very satisfying passage of play for Surrey, who have seldom looked troubled this morning.

Just a hint of the swing and uneven bounce we saw yesterday for Somerset's attack but no more than that.

The innings gap is 184.

Another bowling change for Somerset, who bring on their left-arm spinner, Jack Leach.

Dom Sibley pushes the ball through the off side for one.

Just three runs off the over.

Somerset on the defensive with three fielders on the boundary.

Rory Burns top-edges a sweep and the ball lands safely at long leg for two more runs.

Nonchalantly taken, another excellent slip-catch.

It's a great take from Tom Clark, another wicket for Ollie Robinson.

Martin Emmerson
BBC Radio Newcastle

288 runs in this game for 19 wickets... a crazy old game. A low scoring epic.

With the last pair in they'll play on so we might have a later lunch.

Burns has played really nicely today.

A very typical Rory Burns innings, some nice shots.

It's his 76th 50 of his first-class career.

Surrey 89-0 v Somerset 283

Rory Burns faces Somerset captain Lewis Gregory on 48 not out.

Just outside off stump and stroked through backward point for two.

His second half century of the season, having made 73 in the season opener v Essex.

77 balls with six fours.

An unbroken century partnership between Martin Andersson and Luis Reece has taken Derbyshire to 350-5 against Middlesex, though not quickly enough for another batting point.

Andersson has his second half-century in three games - the last time he made 101, he has 47 runs to find for another. Reece is 47* at the other end.

At Bristol Ian Holland (38*) and Ben Cox (24*) are slowly ticking off the deficit, moving Leicestershire onto 173-5, still 79 behind Gloucestershire's first innings total.

The Notts lead passes 100 as Josh Tongue strokes Jayden Seales for four neatly down the ground.

Worrying times for Sussex after they got off to a great start this morning.

Sussex are trying to wrap this up before lunch with Jayden Seales and Ollie Robinson both returning to the attack.

The last ball of the latest Seales over is short and pulled away by Liam Patterson-White to take the 9th wicket partnership with Josh Tongue to 50 in 61 balls.

This has changed the whole tone of the session after Sussex were all over Notts in the first hour of play this morning.

Josh Tongue gets away with four off an inside edge via a loose defensive prod off Robinson that runs away fine.

Ben Raine gets off the mark with a clip off his pads over mid-wicket off Ben Allison which would have been a one-bounce four on most grounds, but this time plugs 10 yards shy of the rope and dribbles its way agonisingly to the boundary, just beating the chasing fielder.

The deficit is under 50.

Dave Bracegirdle
BBC Radio Nottingham commentator

The lead of 89 is significant now, given where they were.

It always sounds more if you can get the lead into three figures.

Sussex will have to bat better than they did in the first innings.

Somerset have brought the occasional medium pace of Tom Lammonby into the attack and Surrey add eight runs to the total with minimal risk, including a deft tap into cover point by Rory Burns for two of them.

Burns moves to 46 in the next over, driving Lewis Gregory through the off side.
