Worcestershire will have their second taste of floodlit pink-ball Specsavers County Championship cricket later this month – but their bowlers will have a different sort of ball to work with.

The County will take on Nottinghamshire at Trent Bridge from Monday, June 25.

Pink Dukes balls will again be used for Division Two fixtures but pink Kookaburras will be used for the first time for the Division One games.

Another difference this year is that the floodlit matches will be spread across four rounds of fixtures stretching from June until August.

Last year a full pink-ball round was held in late June ahead of England’s first home day-night Test against West Indies at Edgbaston.

Alan Fordham, the ECB’s Head of Cricket Operations, explained: “The view of the ECB Cricket Committee when the first round of day-night matches was reviewed last autumn was that as pink-ball cricket looks likely to continue at international level, it is important for us to continue to provide competitive experience of those different playing conditions for county players.

“This year we’ll be able to compare the performance of the pink Dukes in Division Two with the pink Kookaburras in the Division One fixtures.

“The spread of matches across a handful of rounds provides us with the opportunity to assess different conditions at different stages of the summer.

“We weren’t blessed with great weather for the pink-ball round in 2017, so hopefully with matches in June, July and August, we might even get some warm summer evenings for Championship cricket at some stage this year.”
