England pick Michael Lumb & drop Matt Prior for T20
Left-handed Lumb, 30, is in form for the Rajasthan Royals
England have picked uncapped batsman Michael Lumb for their World Twenty20 squad, with Matt Prior dropped and Craig Kieswetter the only wicketkeeper.
Batsmen Ravi Bopara and Michael Yardy return to the squad while Yorkshire seamer Ajmal Shahzad is also named in a 15 to be captained by Paul Collingwood.
James Tredwell is one of three spinners named for the tournament from 30 April.
Those to miss out include batsmen Owais Shah, Jonathan Trott, Joe Denly and Somerset all-rounder Peter Trego.
Ryan Sidebottom is passed fit despite being forced to fly home early from the tour of Bangladesh with a thigh injury at the start of March.
He is one of just nine survivors from the 15 who represented England in last June's World Twenty20 played at The Oval, Lord's and Trent Bridge.
The six who have been replaced are the injured Dimitri Mascarenhas, Yorkshire spinner Adil Rashid as well as Essex pair James Foster and Graham Napier, Kent's Rob Key and Middlesex's Shah.
Since that tournament England have only played four completed Twenty20 internationals, but it was the unofficial warm-up against their second string Lions team which produced the strongest form guide to the squad selection for the Caribbean.
In that match in Abu Dhabi in February, Johannesburg-born duo Kieswetter (81 off 66 balls) and Lumb (58 not out of 35) produced a match-winning opening partnership after England's own openers, Trott and Denly, had been less convincing.
Lumb, aged 30 and the son of former Yorkshire opener Richard Lumb, is a left-hander who is regarded as a late developer. He has taken his form into the Indian Premier League, with some encouraging showings for the Rajasthan Royals.
Kieswetter, 22, scored a century in his third one-day international after being rushed into England's squad for the tour to Bangladesh.
Bopara, whose technique was exposed in last summer's Ashes, can put his return to England colours down to some promising form for the King's XI Punjab in the same tournament.
Perhaps more of a surprise is the inclusion of Yardy, the 29-year-old Sussex captain who has been out of the England reckoning for three years.
But his ability to provide tidy left-arm spin in addition to his primary batting role on West Indian wickets which tend to lack pace has swayed the selectors.
Revealing the squad, national selector Geoff Miller said: "We believe we've picked a balanced squad that can meet the needs of the Twenty20 format - aggressive batting with variation and strength in depth and various bowling options that accommodate the conditions and surfaces in the West Indies.

"Our fielding, which is such a vital aspect of limited-overs cricket, has improved markedly and there's no reason we can't perform well in what will be a challenging global tournament."
Miller later told BBC Radio 5 live that Kieswetter would invigorate England's batting line-up.
"He has performed really well for Somerset, shown a lot of potential there and performed really well for the Lions as well and then scored a terrific 100 in the 50-over game against the Bangladesh," he said.
"We see him as a very aggressive, inventive, positive opening batsman which gives us options down the order with the wicketkeeper batting up the order.
"Ravi Bopara went away, he had problems - obviously that was why he was left out - and he disciplined his game in New Zealand. He has performed well there and now is getting good experience in the IPL."
He also insisted that Lumb's inclusion, one of four members of the squad born outside England, was the right decision for the team.
He has shown us how good a player he is, he gives us variation up the order being left-handed and he has merited and deserved his inclusion
Geoff Miller on Michael Lumb
"Michael lives here now, his career is here, he is passionate about playing for England," he said.
"He has shown us how good a player he is, he gives us variation up the order being left-handed and he has merited and deserved his inclusion.
"This is nothing new. People have registered for England over the years so we are not setting a precedent here. They have passed all the criteria asked of them so they deserve inclusion for their performances for their counties."
