Northamptonshire 343 v Gloucestershire 19-2
Alex Winter
BBC Radio Northampton sport
Cloudier morning at Wantage Road - we've already had a brief rain delay - and a better day to bowl than yesterday. It's a great chance for Northamptonshire to get on top in the game after putting up 343, a solid score but one which everyone here felt may be a little light.
Will Tavare has been struck a nasty blow on the elbow - a sign that this wicket is not playing true and is expected to become trickier as the game goes on. Both sides are playing specialist spinners as a result.
Northants may need an outstanding session to have a chance of winning this game with the forecast so poor for the next two days of this game.

Andy Umeed to going a tad slower, having just hit his fourth four off the 42nd ball of his innings.

Lancashire 149 v Hampshire 169-6
After losing Ian Holland inside the first ten minutes of the morning session, Hampshire have steadily built a lead over the past 30 minutes.
Liam Dawson has 31 runs from 59 deliveries, with Gareth berg alongside him scoring cautiously with four from 23 balls.
You get the sense that a lead of anywhere close to 100 could be curtains for Lancs unless the track settles down as it gets older.

Derbsyhire 220 v Nottinghamshire 105-3
Dave Bracegirdle
BBC Radio Nottingham commentator
Samit Patel must hate batting at Derby as he has been unfortunately run out in the early stages of the second morning.
Four years ago, on Nottinghamshire’s last County Championship visit, he badly slipped over on a greasy surface and was run out, the video of which went viral.
This morning, backing up, he was stranded after Steven Mullaney’s straight drive brushed the fingertips of bowler Tony Palladino and ricocheted onto the stumps.
Patel made 25 and Alex Hales is the new man at the crease, looking to emulate his white ball form in the longer format.

Warwickshire 126 & 12-0 v Middlesex 161
20 wickets tumbled on day one of Middlesex and Warwickshire's match at Lord's on Sunday as spectators were treated to three innings.
Steven Finn's three wickets in 18 minutes after lunch helped the Division One title holders to bundle bottom-of-the-table visitors out for just 126.
However, Ryan Sidebottom - Australia's answer and namesake to the former England seamer - took 4-29 to restrict the hosts to 161 and leave Warwickshire with four overs to see out to the close of play.
