Age 20, left-handed batsman, right-arm seamer, occasional wicket-keeper

Played six matches in the English county Championship for Middlesex in 2006, averaging only 13 with a top score of 13.
Hit seven fours and a six in his 99 against Scotland in the European Championships before he was run out, which prompted an irate reaction from the flame-haired Dubliner that saw him warned about his future conduct by the ICC.
Age 22, left-handed batsman
An opening batsman who cemented his place in the team with successive unbeaten centuries in the recent World Cricket League in Nairobi, having only made his debut in August 2006.

After a relative failure against Canada, he finished the competition on a high with eight fours in his 84 against the Netherlands.
Age 32, right-arm seamer, right-handed batsman
Australian-born paceman who played for New South Wales before he fell out of favour in the 1999-00 season.
Claimed 3-45 against the United Arab Emirates in the ICC Trophy in 2005, a match in which he also fired four fours and a six in 67 from 68 balls.

Johnston took 4-38 as the Irish rattled South Africa, the world's top-ranked side, in a World Cup warm-up match.
