Rain ruined West Indies Women's chances of levelling their five-match series with South Africa Women when it washed out the fourth One-Day International at Windsor Park in Dominica yesterday.
Chasing a 140 for victory, West Indies were eight without loss off two overs when rain ended the contest for good.
The target was revised to 141 off 43 overs, but ground-staff then ran out of time to get the playing area ready by the 3.55 p.m. cut off time.
Earlier, South Africa had struggled to 139 all out off 43 overs after the bad weather resulted in a delayed start, and forced the game to be reduced to 48 overs per side.
Cri-zelda Brits top scored with 36, while 19-year-old Dane van Niekerk stroked 25, the two sharing a 56-run, sixth wicket stand to pull their side around from 45 for five in the 22nd over.
Both fell via the run out route as West Indies regained control of the contest, snaring the last five wickets for 38 runs.
Left-arm seamer Shanel Daley finished with three for 19 while medium pacer Shakera Selman claimed two for 24.
History was made when the Knight sisters, Kycia and Kyshona were included in the final XI.
The final and decisive is scheduled for tomorrow, also at Windsor Park.
