Trescothick, Schofield and Kirtley recalled by England

The 31-year-old Somerset left-hander was named in the squad for the event in South Africa in September subject to him successfully proving he has overcome the stress-related illness which has forced him to fly home early from his last two England tours.

He is joined in the squad by two players who are yet to feature at international level - Essex batsman Mark Pettini and Sussex all-rounder Luke Wright - while there are shock recalls for Surrey leg spinner Chris Schofield and Sussex seamer James Kirtley.

England are required to trim down this list to 15 names by August 11, giving Trescothick time to consider his situation before committing himself to the two-week tournament.

"Marcus is a contracted player and was named in the England performance squad earlier this summer," explained chairman of selectors David Graveney.

"We've decided to name him in this provisional squad in order to give us more flexibility should it be decided that Marcus is ready to return to international cricket before the tournament takes place.

"We're pleased that Marcus has made a successful return to county cricket this summer and he remains a world-class opening batsman but we will not be placing undue pressure on him to make a return to international cricket without first carefully considering all the issues involved.

"Ultimately, we will be guided by Marcus and the ECB medical staff as to his availability and I would anticipate that further discussions will take place with him before the squad is narrowed down to 15 in mid-August."

Trescothick's return is bound to capture most of the attention, but the recalls of several other players also indicates the selectors' decision to take note of the performances in the domestic Twenty20 Cup.

Among the many players handed recalls is 34-year-old Leicestershire all-rounder Jeremy Snape, whose last one-day international appearance for England was five years ago, while Warwickshire captain Darren Maddy has also been recalled - seven years after his last one-day appearance.

That pair have earned their call-ups for their consistent displays for Leicestershire, who have been the dominant force in Twenty20 cricket for the last few years until being knocked out at the group stage this summer.

Sussex seamer Kirtley also returns three years after the last of his 11 one-day caps following a long battle to cure problems with his action while Lancashire pair Glen Chapple and Mal Loye have also earned recalls having featured in recent years.

But perhaps the biggest comeback is that of Schofield, who was one of the first beneficiaries of the central contract system in 2000 and played two Tests against Zimbabwe as a promising leg spinner.

His career failed to take off after that and after an acrimonious departure from Lancashire three years ago - when he won a claim of unfair dismissal against them - he faded into minor counties cricket until Surrey rescued him with a one-year deal last year.

He has excelled at Twenty20 cricket this season and is the leading wicket-taker in the group stages, claiming 17 victims from his eight matches, in addition to being a useful batsman and fielder.

Several players have missed out despite featuring in the recent one-day campaigns in Australia and during the World Cup in West Indies.

The most high-profile casualties are former captain Michael Vaughan and Andrew Strauss, who both struggled to make an impact in the Caribbean, while Sajid Mahmood, James Dalrymple and Ed Joyce have also been overlooked.

"We've chosen this squad specifically for the ICC World Twenty20 and included a number of players who have an excellent record in this form of the game at domestic level," confirmed Graveney.

"Several players who were in our World Cup squad and featured in the recent Test series against West Indies have not been included but 50-over cricket is a different format and they will remain in our thoughts when we select the squad for the the NatWest Series against India and the forthcoming tour of Sri Lanka."
