The Windies women came up against the powerful South Africa women team on Wednesday night and managed to walk away with a crucial one point, after heavy rains, forced an abandonment of the encounter.
This means that South Africa goes through to the semifinals and moves the Windies team to 7 points, getting them to third on the points table.
If either England or India loses a game, the Windies women will sneak into the semifinals, so the one point at least keeps hope alive in the camp.
South Africa was on 61 for 4 after 10.5 overs, when the heavens opened up.
Mignon du Preez was 38 not out and Chinelle Henry had bagged 3 wickets.
