"Derbyshire's bid for a first County Championship win of the season was put on hold by the Worcestershire batsmen this morning.
"Brett D'Oliveira was out in the first over, but an unbroken third wicket stand of 101 between nightwatchman Ed Barnard, who was on a career-best 53 not out, and Joe Clarke (44).
Following on, Worcestershire are 125-2 at lunch, still 178 runs behind, with a minimum of 64 overs remaining in the game."

Today is very much about in or out, which puts me in mind of the hokey cokey. So, I'd like some suggestions from you for a cricket-themed dance XI - it could be types of dance or dancers, whichever you prefer. Jake Ballet, Charleston Dagnall, Dimitri Macarena that's the kind of thing - but I'm certain you can do better.

"At lunch Yorkshire are 38-0 and have 66 overs to try and get them."

“Ben Duckett has played some marvellous innings so far this season - a mighty 282 not out last time he met Sussex - but his latest fifty has perhaps come in the most challenging circumstances.
“It’s gloomy at Arundel with the threat of drizzle in the air, the ball still fresh and a fine Sussex attack. But Duckett has played steadily for a fifty in 85 balls and seven fours.
“If they bat well here, Northants have a great chance to take control of a Championship match for the first time this season."
Sussex 178 v Northamptonshire 78-1
Ben Duckett hits two fours in three balls off paceman Steve Magoffin to reach an 85-ball half-century at Arundel. He only needs three more runs to reach 700 for the season as Sussex strive for their first breakthrough of the day.

Derbyshire 467-5 dec v Worcestershire 164 & 120-2
Well played, Ed Barnard, who hits off-spinner Wayne Madsen for four to reach a 103-ball fifty for Worcestershire. His partnership with Joe Clarke (41*) is worth 96, but they still trail by 182, having been asked to follow-on.

Warwickshire's Rikki Clarke became the fifth different bowler to find himself on a hat-trick at Old Trafford this week.
After removing centurion Haseeb Hameed and Arron Lilley in successive balls, Clarke was denied by Neil Wagner. He then bowled the Kiwi for a second ball duck!
The other bowlers to have taken two in two during this match are Lancashire's Kyle Jarvis, Tom Smith and debutant Matt Parkinson and Bears' seamer Keith Barker.

It's his second in the County Championship and he is unbeaten on 106 as Lancashire declare on 266-8, leaving Warwickshire a target of 312.

I think that's what you call an 'eventful over'! Rikki Clarke wins an lbw decision against Lancashire centurion Haseeb Hameed, then has Arron Lilley caught behind with his next delivery. Neil Wagner denies him a hat-trick but is then bowled by the all-rounder, who now has figures of 3-34.
Lancashire are 287 ahead with two wickets remaining - but one of them is Liam Livingstone, who is still there with 87 to his name.
