Paul took his second first-class five-wicket haul, while Joseph took three wickets as Barbados posted 294 after electing to bat. They then returned to take four wickets each in Barbados' second innings before half-centuries from Tagenarine Chanderpaul and Leon Johnson helped them run down a 178-run target with eight wickets to spare.
Having lost the toss, Guyana won the early exchanges, with Joseph snaring three wickets in a new-ball burst that reduced Barbados to 32 for 3. A 78-run fourth-wicket stand between Kevin Stoute followed, which ended with a run out of Moseley. Stoute fell for 47 to left-arm spinner Gudakesh Motie as Barbados lost half their side for 123. Then came the substantial partnership of the match, between Kenroy Williams (68) and Justin Greaves, who top-scored with 72. The duo's sixth-wicket stand of 121 hauled Barbados close to the 250 mark before Paul wiped out the lower order as Barbados lost five wickets for 50 runs to be bowled out for 294.
Tagenarine (52) and Chandrapaul Hemraj (79) kickstarted Guyana's replay with half-centuries and a 115-run first-wicket partnership. Barbados chipped away at the wickets thereafter, but Gudakesh Motie's unbeaten 72 steered them to 314 all out. Ashley Nurse and Jomel Warrican took three wickets each.
Joseph and Paul quickly reduced Barbados to 109 for 7 in the second innings. Jonathan Carter prolonged the innings with 53 and a ninth-wicket stand of 86 with Mario Rampersaud, before Barbados folded for 197.
Chanderpaul and Johnson, the Guyana captain, took their team close to the target with a second-wicket partnership of 117 after Hemraj's dismissal for 21. Johnson was bowled by Harding for 61 with Guyana 25 away from the target, but Tagenarine (62*) and Vishaul Singh (22*) sealed Guyana their fourth win in five matches.
