Another good over from Keogh, bowling a tight line to Robson who defends.

Maiden.

Textbook defence from Robson, facing Broad - head right over the ball and a straight bat.

The fifth ball is a massive bumper that flies over Robson's head - and that's a no ball for height.

A single to Robson, turning the next ball to square leg.

That's tea. Middlesex need another 176 off a minimum of 35 overs after the break.

Less devil in the pitch with the older ball and Middlesex must fancy their chances with Robson and Simpson at the crease and Higgins yet to come.

Lovely shot from Madsen, driving McAndrew on the front foot through cover to bring up the Derby 100 in the 21st over.

37 overs left.

Well, here we go. Justin Broad is going to have his first bowl in first class cricket.

Military medium pace. The third ball is nudged away behind square off the back foot by Simpson for one to take the keeper-batsman to 35 - on the day of his 35th birthday.

Robson works the fifth ball away to fine leg for a single.

Rob Keogh will replace Saif Zaib from the Lake End.

A Doug Bracewell no-ball runs away for four byes - handy runs for Lancashire.

Tea is approaching and it is crucial for the Red Rose that Rob Jones and Phil Salt are still together at the start of the final session.

Nathan McAndrew is in the attack replacing Shipley and his fourth ball is driven through mid wicket off a thick edge for four.

The target looks a long way off but Derbyshire are looking comfortable here.

What do you call that, nature? Barely a sprinkle. These hardy chaps are back out and playing again.

Seemingly 36 overs remaining now.

Haseeb Hameed tucks Sean Abbott through mid-wicket and the ball just reaches the rope to take the Notts total to 50.

Hameed is 17 not out, Ben Slater has 34 and Notts need another 245 from 38 overs (6.45 per over).

Zaib bowls on leg stump and Robson works the ball away to the on side for a single.

Simpson goes down the pitch and drives straight down the ground, just past Zaib for four runs.

Du Plooy picks up his first boundary, driving Shipley through mid off for four runs.

Madsen flicks Coles away through the leg side for one.

Du Plooy uses his feet well, going down the track and lofting Coles down to long on for four more.

Lovel on drive by Simpson off Zaib and that's a good sliding stop by Jack White at long on to keep it to one.

It looks like those pesky rain clouds are gathering around the ground again.

Zaib bowls round the wicket to Robson, who shuffles back and across to block.

The last ball is pulled to mid-wicket - and stopped by Northants captain Luke Procter.

Just two singles in six overs for Hampshire. Liam Dawson and Nick Gubbins doing their best to thwart the Somerset attack.

Simpson gets away with a top-edged pull off Taylor which lands in front of backward square for one.

Another short ball and Robson is down on one knee, swaying out of the way.

An early opportunity for off-spinner Will Jacks.

Just two runs and a single for Haseeb Hameed from it.

No alarms for the Notts skipper.

Worcs 242 & 75-2 v Yorkshire 407

Jake Libby has 25, Gareth Roderick has 17, the deficit is down to 90, but the weather doesn't care about any of that.

Shower time. The only big, dark cloud for miles around, according to the radar.

Lovely shot from Guest, who cuts Coles through point off the back foot for four runs.

Successive boundaries for Madsen at the other end off Shipley.

The first is a bit streaky, edged wide of the slip cordon and through third man but the second is a superbly timed cover drive off the back foot.

A single off the fourth ball - and Guest drives to long on for four more.

A testing over from Sean Abbott, but Ben Slater drives the Australian through extra cover for four when he overpitches.

Ten overs completed, 42 left - the Notts target is 297.

A nervy moment for Robson, who gets thick outside edge off Taylor and the ball flies wide of second slip and through to third man for a single.

The partnership is now worth 47 with Simpson.

Lancs 145 & 253-4 v Essex 282 & 292-8 dec

Simon Harmer tries his luck from round the wicket, but that is too short and Rob Jones cuts it away for four.

Jones is 38 not out, Phil Salt has 32 and Lancashire need another 177 from 38 overs.
