The England and Wales Cricket Board have announced the performance squad for this year's international campaign.
The 30-man squad includes the likes of Test and one-day captain Alastair Cook, injured Kevin Pietersen and Stuart Broad, who were all involved in England's Test series draw with New Zealand.
"The players included in this squad reflect the progress they have made with senior England teams and the England Lions over the last 12 months," said ECB selector Geoff Miller.
"All of the players named in the EPS squad have been involved with one or more of the England squads during the winter, with the exception of Chris Tremlett who has been going through a rehabilitation process."
The squad allows selectors to monitor the performances of the international players.
England performance squad:
A Cook, S Broad, J Anderson, J Bairstow, I Bell, R Bopara, T Bresnan, D Briggs, J Buttler, N Compton, J Dernbach, S Finn, A Hales, J Harris, C Kieswetter, M Lumb, S Meaker, E Morgan, G Onions, M Panesar, S Patel, K Pietersen, M Prior, J Root, G Swann, J Tredwell, C Tremlett, J Trott, C Woakes, L Wright
