Vince out for a duckpublished at 12:37 British Summer Time 23 August 2016
Hampshire 70-3 v Somerset
BBC Radio Solent's Kevan James told us to expect spin today at Hampshire, and it appears he was spot on with Somerset's Roelof van de Merwe picking up the wicket of Will Smith, and Jack Leach bowling England's James Vince for a duck.
Lancashire have lost their second wicket at the Oval against Surrey, Haseeb Hameed mistiming a hook and being caught out off the bowling of Stuart Meaker.
Yorkshire six down v Nottspublished at 12:31 British Summer Time 23 August 2016
Yorkshire 51-6 v Nottinghamshire
This is woeful batting from Yorkshire, Tim Bresnan the next man out as he offers no shot to Steven Mullaney and is given out lbw as the ball raps into his pads.
Just as I'm about to hit publish, Brett Hutton finds Jack Leaning's outside edge and Samit Patel takes the catch at third slip.
Hard to believe that Notts are bottom of the table as it stands.
Viljoen strikes on debutpublished at 12:26 British Summer Time 23 August 2016

WICKET Ballance (lbw b Fletcher 1)published at 12:08 British Summer Time 23 August 2016
Yorkshire 36-4 v Nottinghamshire
Yorkshire haven't lived up to expectations for much of the season in the County Championship despite still being second in the table, but this might be their worst showing yet.
Garry Ballance is pinned in front of the stumps by Luke Fletcher, leaving them 36-4 after just over an hour's play.
The hosts usually have quite a strong lower order, but that's not the case today, with Andrew Hodd the only recognised batsman left in the dressing room as Tim Bresnan comes out to the crease.

Division Two round-uppublished at 11:51 British Summer Time 23 August 2016
Northamptonshire 38-2 v Worcestershire
Northamptonshire are playing for pride in Division Two, eighth in the table and out of promotion contention this season. Fourth-placed Worcestershire may still harbour slim hopes of a late push at the top, and they've already taken the wickets of Rob Newton and Ben Duckett at New Road.
Leicestershire have steadied the ship after losing two early wickets against Essex to move on to 29-2, while Glamorgan are now 37-2 against Sussex at Cardiff.
Kent's bowlers have had a good first hour at Gloucestershire as well, as Gareth Roderick has just been dismissed lbw by Darren Stevens to make it 41-2 at Bristol.
Interesting selection for Hantspublished at 11:45 British Summer Time 23 August 2016
Hampshire 31-1 v Somerset
Kevan James
BBC Radio SolentAll-rounder Sean Ervine is back in the side after injury, batting at number three for the first time in the championship this season. He takes the place of Tom Alsop, who has been left out despite hitting a career-best 93 last week at Notts.
Former Derbyshire spinner David Wainwright is making his Hants debut after being signed on a match-to-match deal, but Andy Carter is left out after his impressive performance last week.
The reason for both selections it seems, is that the wicket here is set to turn. Indeed after just 40 mins play, we are seeing the first spinner introduced
WICKET Lyth (run out Mullaney 12)published at 11:39 British Summer Time 23 August 2016

BBC Coventry & Warwickshire SportIt's no surprise that Warwickshire have exercised their right as the away team to bowl first at Chester-le-Street.
It's a very grey and damp looking morning and already Keith Barker has been asking questions of the batsmen.
Durham's in form opener Keaton Jennings has got them on their way, taking advantage of a couple of loose balls from Chris Wright to score successive boundaries.
