ST JOHN'S, Antigua (CMC):

Jamaica are looking to continue their dominance when they face Guyana in a top-of-the-table clash in the fourth round of the Regional Four-Day Tournament, starting today.

At the same time, third-place hosts Trinidad and Tobago are looking to do the same against Windward Islands in Port of Spain, and Barbados are looking to forge ahead at the expense of the Combined Campuses & Colleges in Bridgetown.

At the Vivian Richards Cricket Ground, front-runners and four-time defending champions Jamaica have been unstoppable in this year's tournament, quite like they have been over the last four seasons.

The Jamaicans top the standings with a maximum 36 points following a 91-run victory over Windwards, a 120-run win over Barbados, and an innings and 201-run triumph over Leeward Islands, all on home soil, where they are traditionally very tough to beat.

The nomadic Guyanese are second in the tournament with 24 points, with a 234-run victory over Leewards and a four-wicket victory over CCC either side of a five-wicket loss against Windwards.

Jamaica will have to overcome their travel jitters, the lights and the pink ball to take control against a Guyana side boosted by the return of West Indies batsman Ramnaresh Sarwan.

winning five

The substantive visitors have dominated the Guyanese in this form of the game since the turn of the century, winning five of their last six matches.

The Jamaicans last lost to the Guyanese six years ago when they were beaten by 51 runs at Chedwin Park on home soil.

At Queen's Park Oval, T&T will be looking to rebound from defeat and Windwards will be looking to get back on track after a week of inactivity..

T&T are third in the tournament on 16 points following a 172-run victory over CCC before they took their bye week and returned to lose against long-standing arch-rivals Barbados by five wickets, although they gained first-innings points, last time out.

Windwards rebounded after their defeat against the Jamaicans to overcome the Guyanese, but they will have to work doubly hard to overcome the layoff, which might have broken their momentum.

T&T have been stricken with a number of injuries, creating room for former captain Daren Ganga to make his return, and offering uncapped duo Emile Rajah and Teshawn Castro hope that they may make their first-class debut.

Both sides need a win to keep their chances alive, but T&T are highly favoured, since they have dominated the Windwards since the turn of the century.

The Red Fury have won six of their last seven matches against the Windwards, a spell broken only by a draw two years ago in St Vincent, where they gained first-innings points.

At Kensington Oval, most people have been unkind and have referred to this contest as a matchup between Barbados and Barbados-A, considering the high number of Barbadians in the CCC side.

Both sides are locked on 12 points and this will add to the competitiveness of the match which will also be contested under lights with a pink ball.
