Rampaul has also featured for CPL outfits Barbados Tridents and Trinbago Knight Riders along with English County cricket teams Surrey and Derbyshire.

Rampaul played youth cricket for West Indies and Trinidad and Tobago, playing at the World Under-15 Challenge in England in 2000, and at the 2002 Under-19 World Cup, before breaking the record wicket tally in the regional youth tournament in West Indies after taking 45 wickets in five matches during the 2002 tournament.

By that time, however, he had also made his first-class debut, playing three Busta Cup matches for Trinidad and Tobago during the 2001–02 season and taking six wickets.

However, after taking two wickets, including opener Dion Ebrahim, in the one-day warm-up match against Zimbabwe A,[6] Rampaul played in four of the five ODIs.

He failed to take a wicket in the series, which West Indies eventually claimed 3–2 with a win in the final game, and Rampaul was the most expensive West Indian bowler among those bowling more than four overs per game,[7] Rampaul also went to the South African leg of the tour, and recorded his first five-wicket-haul in first-class cricket, taking five of the first six wickets in a tour match against Free State.

Rampaul's figures of 2-56 from his 10 overs, was lauded as a "marvellous late effort"[10] After once again playing in the Under-19 World Cup, taking nine wickets as West Indies reached the final but ultimately lost to Pakistan, Rampaul played in all five ODIs against England at home, taking four wickets but once again being the most expensive of the regular bowlers.

[17] However, Rampaul sustained a leg injury,[18] and did not play any games during the first-class Carib Beer Series, which his team won.

In July 2006, Rampaul was awarded a cricket scholarship by the Australian High Commissioner to Trinidad and Tobago, and attended coaching sessions in Australia.

[29] He began club cricket towards the end of the month and hoped to represent Trinidad and Tobago to prove his fitness to the national selectors.
