'A pleasure to watch'
Sussex 468-5 v Derbyshire 191
Despite only scoring six with the bat himself for Sussex, the New Zealand international still seems to have enjoyed himself at Derby.
Time for Root to get a double ton?
Yorkshire 475-5 v Surrey 330
Joe Root is 12 away from 200 with four overs left in the day at Headingley. Can he get there tonight?
Close of play at Derby
Sussex 468-5 v Derbyshire 191
Sussex finish day two in a commanding position thanks to Ed Joyce (250) and Luke Wells (116) who put on 310 for the second wicket.
The 250 from Joyce is his highest in first-class score and the innings included five consecutive fours in one Luke Fletcher over.
Derbyshire fought back slightly after tea with Wes Durston taking two wickets and Shiv Thakor taking the other, but the Midlands side have their backs against the wall for the next couple of days.
WICKET Trego (c Hain b Patel 51)
Somerset 295 & 151-8 v Warwickshire 152
BBC WM's Mike Taylor with the details from Edgbaston:
"With the lead climbing towards 300, Peter Trego finally falls, top-edging a sweep at Jeetan Patel, and falling to a catch by Sam Hain, running round to square leg.
"Trego's 94 and 51 are significant contributions in what has turned out to be a relatively low-scoring match. Two wickets to go, but Warwickshire are going to have to make the highest total of the match to win."

Wickets falling at Edgbaston
Warwickshire 152 v Somerset 295 & 136-7
BBC WM's Mike Taylor has more from the ground:
"Short-pitched bowling has featured strongly since tea, and another short ball picked up the seventh Somerset wicket.
"Ryan Davies, keen to counter-attack, hit three fours before pulling Keith Barker to deep backward square leg. The ball has to be hit high to fly out of Boyd Rankin's reach, and it didn't.
"Peter Trego remains steadfast for Somerset though. His 94 in the first innings was vital to keeping Somerset in the game - his second innings, currently worth 48, may turn out to vital in winning it."
