It's all going wrong for Somerset at Edgbaston.

He works Umesh Yadav for his 10th four to raise a half-century in 62 balls.

Nottinghamshire v Middlesex 10-0
It is easy to spot Middlesex's problem this season:
4-4 v Essex
11-4 v Northants
31-4 v Warwickshire
25-4 v Essex
19-5 v Lancashire
It is impossible to mount good totals from these positions.
Middlesex have only recorded two batting points all summer and they can ill afford to slip into another situation like this at Trent Bridge if they want to avoid relegation.
Openers Mark Stoneman and Sam Robson have seen off the first two overs, with Stoneman collecting two boundaries off Jake Ball's first crack.
Durham 250-4 v Leicestershire

James Rew has joined captain Tom Abell in the middle - two batters more than capable of launching some sort of recovery.
Yorkshire v Worcestershire 117-4
Kashif Ali tucks a single into the legside to collect one more run and reach a half-century stand between him and captain Brett D'Oliveira.
It is a comeback of sorts from 67-4.
Kent v Lancashire 217-5
Josh Bohannon's excellent innings is brought to a close!
The part-time spin of Kent captain Jack Leaning does the trick, as coming round the wicket, Bohannon comes down the track, but the ball carries on the angle past his bat and Harry Finch completes the stumping.
A welcome wicket for Kent after a difficult afternoon and the end of a partnership worth 121.
Bohannon's innings lasted 167 balls and has helped his team away from the perilous position of 18-3.
