Durham 113-5 v Sussex
Adrian Harms
Sports reporter, BBC Sussex
Cold days are not the best to be fielding in the slips, but that doesn’t seem to matter to Chris Jordan, who must be one of the best fielders in the County Championship.
A magnificent low catch accounted for Cameron Bancroft, as the new Durham Captain departed for 33 made in 159 balls.
The hosts have struggled on a slow pitch against accurate Sussex bowling, on a day which has seen just six boundaries.
Notts 237-8 v Somerset
Dave Bracegirdle
BBC Radio Nottingham commentator
Lewis Gregory continued his fine start to the season on the first afternoon of Somerset’s Specsavers County Championship match against Nottinghamshire at Trent Bridge.
The seamer, who had taken three wickets in the morning session, took the first one to fall afterwards to speed Notts towards 237 for eight at tea.
Tom Moores and Samit Patel had dragged the home county back towards parity in a stand of 58 before Gregory sent two of Patel’s stumps sprawling for 33.
Moores got to within three of a half century before nicking Craig Overton to slip and the same bowler then bowled Stuart Broad, off his pads, for five.
Middx 175-3 v Lancs
Stevie Eskinazi will be fuming at his dismissal, a strangle down the leg side, but this has been a good session for Middlesex - who are up against a very strong bowling attack here.
Malan is unbeaten on 18 and Max Holden is on 19.
And that dismissal of Stuart Broad at Trent Bridge has brought about the tea interval.
It's also not far away in all our other games and we'll bring you up to date with the latest scores very soon...

Craig Overton bowls round the wicket...
Stuart Broad makes a mess of a leg glance and somehow guides the ball into his middle stump.
This innings could end in a hurry.
Notts 237-7 v Somerset
Wood has no intention of reining it in here and pulls a short one from Jack Brooks through mid wicket for four.
Four more is off a flayed drive from a thick edge, which scuttles to third man.
Warwks v Kent 204-4
There's the prize wicket...
A beautifully flighted ball from Jeetan Patel that dips late and Zak Crawley gets an inside edge through to the keeper.
Warwickshire right back in the game now.
Ollie Robinson is in the middle with Heino Kuhn.
Warwks v Kent 198-3
Breakthrough!
Daniel Bell-Drummond is slightly late on a defensive jab off Henry Brookes and edges low to the keeper.
Warwickshire having a much better time of it this afternoon.
The new batsman is Heino Kuhn.
Surrey 196-4 v Essex
Stand and deliver from Surrey's Will Jacks!

Notts 223-7 v Somerset
Seven down!
Craig Overton angles one across Tom Moores, who fences to second slip. A sharp chance but Trescothick hangs on.
Time for Stuart Broad to have a bat.
Warwks v Kent 194-2
Image source, Getty ImagesThere it is! Off 165 balls with 17 fours.
That's his second century in first class cricket.
Yorkshire 194-2 v Hampshire

Glamorgan 209-3 v Northamptonshire
Alex Winter
BBC Radio Northampton sport
Marnus Labuschagne - we've plumped for Lab-u-shane as a pronunciation - has proved an immediate success here for Glamorgan.
Conditions are very docile, batsmen have been able to trust the pitch and punch at balls nowhere near a half-volley, and the Australian has bided his time well to take full advantage on Championship debut.
I've been impressed with his leg side play - using any angle available to turn off his legs. Some of his timing has been exceptional.
He and Billy Root have quickly picked Glamorgan up after losing a wicket half and hour after lunch to their first point of the summer.
Warwks v Kent 187-2
Jeetan Patel teases him with flighted deliveries outside off and Crawley defends.
Middx 151-3 v Lancs
Ugh, Stevie Eskinazi is strangled down the leg side as he looks to glance Tom Bailey to fine leg and feathers it to Brooke Guest.
The new batsman is Max Holden.
Warwks v Kent 187-2
Jeetan Patel bowls to Zak Crawley, now on 95.
His first ball ricochets off the pads for four leg-side byes and the fourth is driven through the covers for four. 99.
He looks for a single to square leg off the last but there's no run there.
Surrey 181-4 v Essex
Image source, Rex FeaturesAnd the old commentator's curse strikes again.
Ben Foakes gets a fine edge on a Simon Harmer delivery that ricochets off wicketkeeper Robbie White and into the hands of Sir Alastair Cook at first slip.
Welcome breakthrough for Essex. Will Jacks in at six.
Surrey 181-3 v Essex
Image source, Rex FeaturesAll Surrey in this afternoon session. Little to shout about for Essex with the ball.
Ryan Patel and Ben Foakes have now added 95 for the fourth wicket without too much alarm.
