The Windward Islands defeated Trinidad and Tobago by two wickets in the fifth round of the West Indies Cricket Board Regional Under-19 50 over championships at Enmore in Guyana on Sunday.
The loss was T&T’s third straight defeat in the competition and it also ended any chance of T&T lifting the trophy.
Batting first, T&T were restricted to 149 for eight aoff 50 overs with opener Jeremy Solozano top-scoring with 28, and off-spinner Gidron Pope snaring four for 23.
In reply, the Windwards achieved their target with just seven balls left in the contest, with Ryan John getting 29 and tail-ender Sherman Lewis scoring an invaluable unbeaten 26.
Fast bowler Akeel Seetal (three for 31) and off-spinner Samuel Roopnarine (three for 36) finished with three wickets apiece for T&T.
At the Demerara Cricket Club, the game between ICC Americas and Barbados finished in a no-result after rain allowed just 26.3 overs, with ICC Americas reaching 55 for four.
Elsewhere, Jamaica suffered a batting meltdown and crashed to a 68-run defeat against hosts Guyana.
Chasing a demanding revised target of 175 off 30 overs under the Duckworth/Lewis Method, Jamaica were bundled out for 107 off 29.3 overs at Bourda.
