LONDON - England have added wicketkeeper Sam Billings to their provisional squad for next year's World Cup in place of the injured Craig Kieswetter. Billings, 23, is a tidy keeper and innovative middle-order batsman who was in sparkling form for his county Kent last season. Kieswetter, a member of England's victorious World Twenty20 team in 2010, is suffering from problems with his vision after being hit by a ball while batting in a match in July.
