Guyana pushed the pace of the game, almost turning the encounter into a track meet with their style of play.
However, it was the third period that really made the difference as the Guyanese locked down the visitors with their defence, only allowing Bermuda to score five points in the third period.
Guyana continued their fast paced tempo as Travis Burnett led the Guyanese team in scoring with 16 points while Captain Akeem Kanhai had 14 points and seven rebounds. Shelroy Thomas also had 13 points in the win.
Coach of the Guyanese side, Darcel Harris will aim to utilize most of his younger players for evaluation purposes in the final game set for Saturday from 20:00h.
