Rilee Rossouw refuses to be tied down. He absolutely leathers a ball from Duanne Olivier through the covers for four, and in the next over by Ben Coad, he holds the pose for a few moments after a more controlled stroke brings him the fifth boundary of his innings.

When faced with a batsman in this mood, it's comforting to know you have 554 runs on the board, so Yorkshire certainly won't be panicking. Rossouw is 28 not out, and Sam Northeast has 38.

Josh Davey in the attack now, bowling full and straight every time.

Ben Slater shows the bat maker's name with every block.

Stevens offers Ambrose a bit of width outside off but the keeper-batsman is happy to leave.

Probably best early on in his innings with three slips in place.

Maiden over.

Change of bowling at Trent Bridge, where Craig Overton alternatives between forcing Slater to dance to chin music and then go forward to defend.

He's equal to the task though and takes a single off the fifth.

Fletcher sees out the over.

With the scoring rate too high for their liking, Surrey switch tactics and bring on left-arm spinner Freddie van den Bergh. His first over of the morning is a maiden - no mean feat with Ryan ten Doeschate in aggressive mood. He now has 61 and Dan Lawrence is 93 not out and seemingly willing to bide his time to reach three figures.

Kolpakker to Kolpakker at the Ageas Bowl and Rilee Rossouw helps himself to back-to-back fours off Duanne Olivier.

The first is slammed through cover off the front foot and the second, a little shorter in length, is pulled away with some authority.

A third boundary follows as the over costs Olivier 14 runs. Told you Rossouw doesn't like hanging around (see 11:23 entry).

Here's the latest in the second division games, away from Chester-le-Street:

Northants continue to pile on the runs at Cardiff and will need to continue to do so after their Glamorgan hosts racked up 570-8 declared.

The visitors are 267-0 with Ricardo Vasconcelos on 144 and Rob Newton on 92.

We could be in for a close contest at Bristol, where Gloucestershire are 214-5 against Derbyshire.

They trail by 77.

Leicestershire are struggling a little at home to Worcestershire, where they're 200-5 and trailing by 353.

Lancashire continue to build their lead against Middlesex at Lord's where they're 289-4 and 24 ahead.

Ryan ten Doeschate forces the opening delivery of a new Tom Curran away off the back foot for four, and a cover drive later in the over carries him to a 54-ball half-century.

By way of celebration, he repeats the stroke, this time a little squarer, and again finds the boundary. Fine counter-attacking batting by the Essex captain, who now has 10 fours in total. Why bother running when you don't have to.

Too short from Brooks and Slater pulls him behind square for four to take Notts past 50.

No single at the end of the over this time, so Fletcher to face Gregory.

Slater pounces on a leg side ball from Gregory and guides it away through mid-wicket for four.

He takes a single off the fourth so can Fletcher see out the over?

He can. The last ball is drifting down leg and a slightly airborne but safe paddle to leg brings the nightwatchman four.

Essex skipper Ryan ten Doeschate is seemingly intent on not allowing himself to be tied down by Surrey's pace attack, and after a slightly fortuitous boundary from a thick edge in Morne Morkel's last over, he adds another with an authentic off-drive from an overpitched delivery.

He and Dan Lawrence have now posted a half-century partnership - with Lawrence now just nine runs short of a century.

A bit of a hold up at Edgbaston as a member of the ground staff is in the middle with what appears to be a bucket of sand, presumably to repair a part of the wicket.

A rare leg side ball from Stevens but Sibley can't get a bat on it.

The next ball is pushed out to point for a couple.

Shot! Sibley drives through the covers off the back foot for a couple more. That's the 150.

A slice of luck for Sam Northeast as Yorkshire fast bowler Duanne Olivier bangs one in short and he is late on an attempted hook shot, but collects four off the edge as the ball flies away over the head of the keeper.

Northeast made a big century against Essex last week, and Hampshire could do with another from him today if they are to avoid the prospect of having to follow on.

A bit of width from Jack Brooks this time and Ben Slater drives firmly to mid off for four to move to 17.

Time for Fletcher to face Gregory now.

Just the one run from a tidy Darren Stevens over but Matt Milnes loses his radar a little and Sibley dispatches him for successive fours off his second and third ball.

So far so good for the Bears.
