CHENNAI (Agencies) - Ireland's dramatic giant-killing World Cup win over England could be repeated in future despite a decision to reduce the event to 10 teams, world cricket's top administrator said on Saturday. As there are only 10 Test-playing countries, many second-tier or associate nations such as Ireland fear they could be frozen out by the move. Ireland created one of the great WC shocks by beating England by three wickets in Bangalore on Wednesday, with Kevin O'Brien scoring the fastest hundred in the events history.
