Alastair Cook in but Kevin Pietersen out of England's provisional 30-man World Twenty20 squad Cook is a player who generally achieves his aims and he has been open in the past about playing in the World Twenty20. He was a late addition to England's Twenty20 squad for the series against Pakistan earlier this year although he did not play a game. It was also felt that Hales had to make runs against the West Indies recently or Cook would take his place for Twenty20s against South Africa later this summer. Those matches will be useful practice for the World Twenty20 which starts for England against Afghanistan on Sept 21. It was no surprise Kevin Pietersen was not part of the squad named today, a sign that his retirement from one-day cricket is set to continue for the foreseeable future. His game of brinkmanship with the ECB last week - which culminated in him offering to play in all forms of the game in return for playing the whole IPL - was easily dismissed by Andy Flower, the team director. What would have been harder to overlook is Pietersen's talent as a Twenty20 batsman. Instead there are squad places for Michael Lumb, who opened in the last World Twenty20, and Ian Bell. Also included is Yorkshire's Joe Root. Michael Vaughan believes he could be the next Geoffrey Boycott. Boycott believes he will be the new Vaughan. It's finding the new Pietersen that could be tricky. England's provisional 30-man squad: Stuart Broad (Nottinghamshire) (Capt), James Anderson (Lancashire), Jonathan Bairstow (Yorkshire), Gareth Batty (Surrey), Ian Bell (Warwickshire), Ravi Bopara (Essex), Scott Borthwick (Durham), Tim Bresnan (Yorkshire), Danny Briggs (Hampshire), Jos Buttler (Somerset), Alastair Cook (Essex), Steven Croft (Lancashire), Steven Davies (Surrey), Jade Dernbach (Surrey), Steven Finn (Middlesex), Alex Hales (Nottinghamshire), Craig Kieswetter (Somerset), Michael Lumb (Nottinghamshire), Stuart Meaker (Surrey), Eoin Morgan (Middlesex), Graham Onions (Durham), Samit Patel (Nottinghamshire), Matt Prior (Sussex), Joe Root (Yorkshire), Ben Stokes (Durham), Graeme Swann (Nottinghamshire), James Taylor (Nottinghamshire), James Tredwell (Kent), Chris Woakes (Warwickshire), Luke Wright (Sussex).
