In reply, Jamaica had a bad start were 61-5 in the 15th over before being bowled out for 168 in the 37th over. Left-arm spinner Larry Edward celebrated his 26th birthday in style with a match-winning spell of 3-36 off 10 overs.
When Windwards batted, Andre Fletcher made 60 from 51 balls at the top of the order with four fours and three sixes.
Cottoy was named the CG Insurance Man-of-the-Match, as he continued his good form to follow up his career-best 72 in the previous match against Trinidad & Tobago Red Force. Volcanoes were 171-5 after 40 overs but Cottoy raised the tempo with a number of breathtaking shots as and the last 10 overs yielded 89 runs.
Andre McCarthy top-scored for Jamaica with a run-a-ball 55 which included six fours and a six as he maintained good form - his previous knocks were 48 against Guyana Jaguars and 40 against Trinidad & Tobago Red Force.
Fabian Allen played a number of brave shots in 39 from 43 balls. At the end, Fletcher showed his new skill set as a leg-spinner and captured the last two wickets.
“It’s always good to perform for your team especially in victories. I’m just glad I’ve been able to put up my hand and bat deep into the innings and it paid dividends,” said Cottoy. “We have to take it one game at a time although it feels good to win two out of three.”
