Shivnarine Chanderpaul, the game's only centurion, set up Guyana's 10-wicket win over Trinidad & Tobago in Providence. His 143, coupled with left-arm spinner Veerasammy Permaul's match haul of nine wickets arrested Guyana's three-match winless streak, taking them close to the top spot.
T&T managed only 162 in the first innings after winning the toss - courtesy Permaul's 4 for 30 and Raymon Reifer's 3 for 34 - before Chanderpaul struck his second century in as many games. He came in when Guyana were 94 for 3 and added 141 runs for the fourth wicket with captain Leon Johnson, whose 69 was the second-highest score of the match. Chanderpaul followed that up with an 89-run partnership for the sixth wicket with Reifer (38) as Guyana posted 378. Imran Khan's legbreak fetched him four wickets.
Trailing by 216, T&T's batsmen showed little resistance in their second innings against Permaul after a brief second-wicket stand of 93 between opener Kyle Hope (40) and Isaiah Rajah (63). Permaul troubled the lower order and T&T soon slipped from 208 for 5 to 235 all out, to set Guyana a target of only 20 runs.
Openers Shimron Hetmyer (17*) and Rajendra Chandrika (4*) took just 16 balls to complete the win. The 42-year old Chanderpaul was named the Player of the Match.
Only 74.4 overs were bowled in Dominica as persistent rain breaks meant the fixture between third-placed Barbados and fourth-placed Windward Islands ended in a draw.
Barbados captain Kevin Stoute was the match's only half-centurion after they were asked to bat. He scored an unbeaten 50 after they were reduced to 118 for 6. His knock came on the fourth day after only 82.4 overs were bowled in the game's first three days. Barbados declared on 200 for 8 while Windward Islands' Mervin Matthew took four wickets.
Windward Islands batted for 11 overs, which saw openers Devon Smith (14*) and Tyrone Theophile (27*) remain unbeaten, scoring 42 together before play ended.
