Sam Cook into a seventh over.

Scott Read
BBC Radio Lancashire

Good over for the Bears.

Beau Webster is off the mark immediately with a couple off Sam Cook and Warwicks are finally in front.

Hants 238 & 311-8 v Somerset 288
Charlie Harden
BBC Radio Solent commentator
He's [Gregory] getting the ball to move in late and quite a similar dismissal to that of Ben Brown.
Just swinging back in and the ball beating the bat of Kyle Abbott, making its way onto off-stump.
Gloucs 200-4 v Lancs - lead by 96 runs
A single for James Bracey (70 not out) sees Gloucestershire edge up to 200-4.
Their lead is getting close to three figures now.
Hain c Harmer b Cook 0 (Warks 14-3 v Essex - trail by 1)
Essex are right on top!
Warwickshire have lost three wickets without adding a run as first-innings hero Sam Hain goes for a five-ball duck.
It's a familiar combo as Sam Cook draws the edge and Sam Harmer takes a super catch at second slip.
Beau Webster is in.
Abbott b Gregory 5 (Hants 311-8 v Somerset - lead by 261 runs)
Two in the over for Lewis Gregory!
A bit of a carbon copy of the wicket he just got a few minutes earlier.
This time, though, there is no hint of an inside edge as Kyle Abbott goes for a big slog and sees his off and middle stumps dislodged.
Somerset on a roll - this match has turned on it's head once more after lunch.
Northants 345-8 v Middlesex 341
Liam Guthrie hammers Naavya Sharma through the legside to collect his second boundary of the over.
It takes him to 30 off just 25 balls and takes Northants into the lead.
Brown b Gregory 66 (Hants 310-7 v Somerset - lead by 260)
Big celebrations from Somerset captain Lewis Gregory who gets the danger man Ben Brown!
A hint of in-swing from Gregory who finds the gap as Brown goes for a big slap into the off side - there may be a small inside edge here and Brown's off-stump tumbles.
Gregory knows how big that wicket is - his side's third in the first hour after lunch.
