Jon Culley at Notts 14-1 v Derbyshire
It is already a momentous day for Conor McKerr, the South African-born fast bowler who has signed for Derbyshire from Surrey on a 28-day loan following injuries to Will Davis and Hardus Viljoen. The 19-year-old, who has a UK passport, is tall and solidly built and clearly has some pace and now has his maiden first-class wicket, striking with his fourth delivery at this level when Jake Libby obligingly edged one to Wayne Madsen at first slip, the batsman no doubt reflecting as he walked back to the pavilion that he might have been better advised to leave well alone. McKerr and Luis Reece are the two changes for Derbyshire, replacing Ben Slater and Rob Hemmings. Notts have made one change, forced on them by the ECB, as Stuart Broad is rested and Luke Wood steps up for his first Championship match of the season.
Paul Edwards at Lancashire v Yorkshire
This will be the 269th Roses Match and the second in a fortnight. As if in disapproval of such haste, rain has delayed the start of Lancashire innings. The visitors won the toss and opted to bat. Yorkshire are unchanged from the last game whereas the Lancashire team shows three changes, Saqib Mahmood, Luke Procter and Jordan Clark replacing Liam Livingstone (whom is with the Lions, we presume), James Anderson (torn groin) and Simon Kerrigan (omitted). Neither team has played a first-class fixture since they last met and all the players might think the world a better place if they had spent four days in Tunbridge Wells.
