Nottinghamshire 322-9 v Yorks 264
Hang on, looks like Tom Moores is doing a Jordan Thomas. Hunting down a century alongside the tail.
He's on 87, with eight fours and three sixes.
Moores is farming the strike well. Can he make it to 100?
These are useful runs for Nottinghamshire.
Melton lbw b Parkinson 0 (Leicestershire 199 v Derbyshire 408)
That's the innings. Dustin Melton is trapped lbw for a golden duck and Derbyshire finish with 408 and a lead of 209.

Jordan Cox (165*) and Jack Leaning's (109*) second-wicket stand is worth 228. Mammoth effort.
Middlesex 252 v Hamps 269-6
More on Liam Dawson's injury.
Our friends at BBC Radio Solent seem to think it's a twisted ankle.
Whatever the injury we wish him well, hopefully it's not too serious and we'll see him take to the field tomorrow morning.
