Until today Tom Haines had a highest score of 11 in first-class cricket and when he joined Phil Salt in the middle in the fourth over of the day nobody could have guessed what was to come.

By the time he departed the 19-year-old left-hander had 124 runs to his name and his second-wicket partnership with Salt was worth 244, the highest for that stand in a match between these two.

Salt also enjoys playing against Durham. His previous best was 72 in Chester-le-Street last September. Today he will be on 126 when he resumes after tea.

It’s easy to say this is a track for the batsmen but Durham’s pace attack has generally lacked potency this season in a first innings. There’s every reason to believe they will concede 400+ for the third time after putting their opponents in, just like they did at home to Leicestershire and away to Derbyshire.

Ross Taylor walks off for a bite to eat on 110.

It's been a marvelous innings so far from the New Zealander has struck 20 boundaries and found a fine partner in Billy Root (32 not out).

Essex look set to face a mammoth first-innings total.

Surrey’s session again as they add 141 for just the loss of their captain Rory Burns, lbw playing across the line to Lewis Gregory for 66.

Somerset’s Tom Abell has rung the changes, so far to little avail, and must already be ruing his decision to give Surrey first use of what looks a pretty good batting pitch.

Well batted!

New Zealand batsman Ross Taylor reaches his maiden century for Notts off just 124 balls.

It's been a dominant innings from the 34-year-old - he's hit 18 boundaries.

Notts are in command at Chelmsford.

That's all from me for now.

Gary Smee, it's over to you.

Daryl Mitchell reaches his 32nd century in first class cricket with a neat square drive off Stephen Parry.

161 balls and 17 fours.

These are still worrying times for Yorkshire, but this is a mini-recovery for the visitors after slumping to 21-3.

Gary Ballance has 22 and Harry Brook is on 15.

Ross Whiteley takes Worcestershire past the 200-mark with a neatly struck on drive off the bowling of Lancashire's Tom Bailey. He swings Jordan Clark on to the on side for his second maximum and picks up another four down the ground.

He's now unbeaten on 32 with five fours and two sixes.

His partnership with Daryl Mitchell is now worth 66 runs. Mitchell is 87 not out.

Tom Haines is finally out for 124 off 167 balls, caught by Paul Collingwood at slip off leg-spinner Cameron Steel.

The 19-year-old gets a standing ovation from the Arundel crowd.

Meanwhile Kent have been bowled out for 197 at Tunbridge Wells by Warwickshire - left-arm seamer Keith Barker starring with 5-32.

We have play in Swansea!

I'm going to check how many overs are scheduled for the day - I'm going to guess at something silly like 64...

Hurrah, they're starting in less than 10 minutes between Glamorgan and Derbyshire.

Phil Salt and Tom Haines continue on their merry way for Sussex - the pair's stand is now worth 237 and is the highest for any wicket for the county against Durham. The hosts are 246-1 at Arundel.

Kent have collapsed to 192-9 against Warwickshire at Tunbridge Wells, Leicestershire are 160-3 against Middlesex and Northants are 116-3 versus Gloucestershire in the day-night game.

Run-scoring is a tough task at Southampton at the moment, with just four runs coming from Yorkshire's Harry Brook and Gary Ballance in the last five overs.

The men out are Alex Lees, Cheteshwar Pujara and Adam Lyth. Hampshire are firmly on top.

He's not quite matching the fireworks we saw from England at Trent Bridge but this has been a fine counter-attacking cameo from Ross Whiteley so far, who has scored all 14 of his runs in boundaries, including a superb pull shot off Joe Mennie for a maximum.

Daryl Mitchell is 82 not out at the other end.

A few less names in the bowlers column...

Joe Mennie (Lancs) 4-37

Keith Barker (Warwickshire) 3-29

Rory Burns may have departed, but the runs are still flowing for Surrey via Scott Borthwick, who reaches his 50 from exactly 50 balls with nine fours.

Leicestershire 138-3 v Middlesex

BBC London's Kevin Hand reports a nasty sounding injury for Leicestershire's Colin Ackermann.

Thankfully he appears to be okay and will resume his innings on 55...
