Scotland, ranked 15th in the world, started their Men's T20 World Cup campaign in brilliant fashion by shocking two-time winners West Indies.
Chasing 161 to win, a mixture of woeful batting and disciplined bowling saw the Windies bowled out for 118, to lose by 42 runs in Group B.
Scotland made 160-5, with opener George Munsey striking an unbeaten 66 from 53 balls.
Ireland start their campaign against Zimbabwe in the other Group B game.
"It is a special win for us," said Scotland captain Richard Berrington, whose side beat Bangladesh in last year's World Cup. "A lot of hard work has gone into getting us to this point in the last 12 months.
"I'm extremely proud of the boys for going out there tonight and showing off our skills."
The result means West Indies, who are ranked seventh in the world, will likely need to win both of their remaining games to progress.
They face Zimbabwe on Wednesday (09:00 BST), while Scotland face Ireland (05:00) knowing a victory will likely see them qualify.
The top two sides from each group will qualify for the Super 12s, which start on 22 October. The winner of Group A and runner-up from Group B will face England.
