Rain, at 22:40hrs, had the final say in the truncated final practice match under lights at the National Stadium on Friday evening as the National cricket team, which wings out on Tuesday for Trinidad to participate in the 2014 regional Super50, wrapped up their preparations for the eight-team event.
Narsingh Deonarine and Royston Crandon added 73 for the sixth wicket to lift the Guyana side, chasing the 194-8 in 50 made by the Rest Team, from 80-5 off 23 overs to 153-5 in 42 overs when rain stopped the contest for the final time giving Guyana victory by five runs on the Duckworth/Lewis system.
Deonarine hit four fours from 84 balls in his undefeated 56 while fellow Berbician Crandon was 22 not out from 44 balls after Robin Bacchus (8), Leon Johnson (1) and Skipper and in form batsmen Christopher Barnwell (7) all struggled to maintain any momentum under overcast skies.
Pacer Raun Johnson had 3-30 from 10 impressive overs, while off-spinner Zaheer Mohamed and Keon Joseph, who bowled with some pace, had a wicket each.
Earlier, Assad Fudadin (46) and Sewnarine Chattergoon (74) provided a solid 117-run foundation for their team but none of the other batsmen reached 30 with Rajendra Chandrika (29) and Vishal Singh (26) being the next best scores.
Ronsford Beaton took 3-30 while Barnwell supported with 2-29. (Sean Devers)
