Jack Leach finally gets his first bowl of the match after being a spectator in the first Hampshire innings.
He begins with a maiden, including half an appeal for a bat-pad catch against Tom Alsop.
Hampshire with more digging in to do for the last 14 overs of the day.
Lancashire v Glamorgan 344
Timm van der Gugten's swashbuckling innings of 23 comes to an end at the hands of Saqib Mahmood and that's Glamorgan's first innings done.
344 is a pretty solid effort from the visitors. Above par I'd say.
Leicestershire 496 v Surrey 111-0
Surrey openers Mark Stoneman and Rory Burns both go to fifty in the same over.
Batting continues to look nice and easy at the Uptonsteel County Ground.
Middlesex 210 v Gloucs 273

They get a handy lead of 63 but at 191-4 it seemed they were on course for a much bigger advantage.
Middlesex 210 v Gloucs 264-9
One to go for Middlesex.
Ethan Bamber gets Tom Smith caught behind.
The lead is 54 and you'd have to say this game is still nip and tuck.
Higgins lbw b Murtagh 49 (Middlesex 210 v Gloucs 260-8)
Middlesex are fighting back after tea!
Tim Murtagh gets Ryan Higgins lbw one short of his half-century. It was a rapid 43-ball innings.
Gloucestershire's lead is exactly fifty. How many more can their last couple of wickets stretch it to?
Lancashire v Glamorgan 314-9
Lancashire have picked up a couple of quick wickets at Old Trafford.
First Matt Parkinson removed Glamorgan debutant Michael Neser for 17 and Saqib Mahmood has just dismissed Callum Taylor lbw for a fine 58.
Lawrence b Paterson 11 (Essex 99 & 89-3 v Nottinghamshire 323)
Image source, Rex FeaturesStump cartwheeling and bails flying everywhere!
Dan Lawrence is bowled by Dane Paterson for 11 and Essex are in all sorts of bother now.
Lawrence on the walk is beaten on the outside and his off stump is reeling.
Notts have Essex three wickets down now and they're still 135 runs behind.
Holland lbw b Overton 19 (Hampshire 79 & 31-1 v Somerset 336)
Hampshire's rearguard defence against Somerset in their second innings is finally breached after 24 overs.
Craig Overton pins Ian Holland leg before to bag his 350th first-class wicket.
Hampshire still 226 runs adrift.
Libby c Hain b Stone 74 (Warwickshire 343 v Worcestershire 125-3)
Jake Libby denied another ton as Olly Stone has him caught at forward short leg for 74.
Nice bit of bowling around the wicket from the England seamer and Hain clung on well to the chance off the face of Libby's bat.
Northants 491-9 v Sussex 106 & 68-4
It's the Ben Sanderson and Gareth Berg show once again.
Sanderson has just picked up his second wicket of the innings, removing Tom Clark for 13.
All 14 wickets that Northants have taken in this game have gone to the two pacemen. Seven each.
Yorkshire 143-3 v Kent 305
Gary Ballance brings up his half-century at Headingley.
It's come in good time too - off 89 balls with eight fours and a six.
Still very much in the balance this one.
Image source, Rex FeaturesLancashire v Glamorgan 302-7
Callum Taylor becomes the third Glamorgan batsman to go to a half-century in this innings.
And he's helped take his side past 300 and to three batting bonus points.
With a poor forecast for the rest of the game in Manchester, it may all be about how many bonus points the two sides can earn.
Essex (99 & 86-2) trail Nottinghamshire (323) by 138 runs
Dan Lawrence is wrapped on the pads by Luke Fletcher and Notts are convinced the England batsman is plumb.
Not out is Steve O'Shaunessy's reply and Fletcher looks a touch puzzled by that.
Northants 441-9 dec v Sussex 106 & 66-3
Sussex's batting woes are continuing in Northampton.
Australian debutant Travis Head has just been dismissed for eight by Gareth Berg.
There are still 27 overs remaining today - can Northants wrap up a two-day victory?
